Is Science Self-Correcting?

A long-time colleague, in response to a provocative article about the sins of scientists, characterized it as “garbage” and asserted that science is self-correcting.

I should note here that my colleague abhors “extreme” views, and would cross the street to avoid a controversy. As a quondam scientist, he thinks of a challenge to the integrity of science as “extreme.” Which strikes me as an unscientific attitude.

Science is only self-correcting on a time scale of decades, and even centuries. Wrong-headed theories can persist for a very long time. And it has become worse in the past six decades.

What has changed in the past six decades? Sputnik spurred a (relatively) massive increase in government-funded research. This created a new and compelling incentive: produce research that comports with the party line. The party line isn’t necessarily the line of the party then in power, but the line favored by the bureaucrats in charge of doling out money.

On top of that, politically incorrect research is generally frowned upon. And when it surfaces it is attacked en masse by academicians who are eager to prove their political correctness.

Thus it is that the mere coincidence of a rise in CO2 emissions and a rise in temperatures in the latter part of the 20th century became the basis for kludgey models which “prove” AGW — preferably of the “catastrophic” kind — while essentially ignoring eons of evidence to the contrary. Skeptics (i.e., scientists doing what scientists should do) are attacked viciously when they aren’t simply ignored. The attackers are, all too often, people who call themselves scientists.

And thus it is that research into the connection between race and intelligence has been discouraged and even suppressed at universities. This despite truckloads of evidence that there is such a connection.

Those two examples don’t represent all of science, to be sure, but they’re a sad commentary on the state of science — in some fields, at least.

There are many more examples in Politicizing Science: The Alchemy of Policy-Making, edited by Michael Gough. I haven’t read the book, but I’m familiar with most of the cases documented by the contributors. The cases are about scientists behaving badly, and about non-scientists misusing science and advocating policies that lack firm scientific backing.

Scientists have been behaved badly since the dawn of science, though — as discussed above — there are now more (or different) incentives to behave badly than there were in the past. But non-scientists (especially politicians) will behave badly regardless of and contrary to scientific knowledge. So I won’t blame science or scientists for that behavior, except to the extent that scientists are actively abetting the bad behavior of non-scientists.

Which brings me to the matter of science being self-correcting. I am an avid (perhaps rabid) anti-reificationist. So I must say here that there is no such thing as “science.” There’s only what scientists “do” and claim to know.

It’s possible, though not certain, that future scientists will correct the errors of their predecessors — whether those errors arose from honest mistakes or bias. But, in the meantime, the errors persist and are used to abet policies that have costly, harmful, and even fatal consequences for multitudes of people. And most of that damage can’t be undone.

So, in this age of weaponized science, I take no solace in the idea that the errors of its practitioners and abusers might, someday, be recognized. The errors of knowledge might be corrected, but the errors of application are (mostly) beyond remedy.

Here’s an analogy: The errors of the builders, owners, captain, and crew of RMS Titanic seem to have been corrected, in that there hasn’t been a repetition of the conditions and events that led to the ship’s sinking. But that doesn’t make up for the loss of 1,514 lives, the physical and emotional suffering of the 710 survivors, the loss of a majestic ship, the loss of much valuable property, or the grief of the families and friends of those who were lost.

In sum, the claim that science is self-correcting amounts to a fatuous excuse for the irreparable damage that is often done in the name of science.

AGW in Austin? (II)

AGW in Austin? (II)

I said this in “AGW in Austin?“:

There’s a rise in temperatures [in Austin] between the 1850s and the early 1890s, consistent with the gradual warming that followed the Little Ice Age. The gap between the early 1890s and mid-19naughts seems to have been marked by lower temperatures. It’s possible to find several mini-trends between the mid-19naughts and 1977, but the most obvious “trend” is a flat line for the entire period….

Following the sudden jump between 1977 and 1980, the “trend” remains almost flat through 1997, albeit at a slightly higher level….

The sharpest upward trend really began after the very strong (and naturally warming) El Niño of 1997-1998….

Oh, wait! It turns out that Austin’s sort-of hot-spell from 1998 to the present coincides with the “pause” in global warming….

The rapid increase in Austin’s population since 2000 probably has caused an acceleration of the urban heat-island (UHI) effect. This is known to inflate city temperatures above those in the surrounding countryside by several degrees.

What about drought? In Austin, the drought of recent years is far less severe than the drought of the 1950s, but temperatures have risen more in recent years than they did in the 1950s….

Why? Because Austin’s population is now six times greater than it was in the 1950s. The UHI effect has magnified the drought effect.

Conclusion: Austin’s recent hot weather has nothing to do with AGW.

Now, I’ll quantify the relationship between temperature, precipitation, and population. Here are a few notes about the analysis:

  • I have annual population estimates for Austin from 1960 to the present. However, to tilt the scale in favor of AGW, I used values for 1968-2015, because the average temperature in 1968 was the lowest recorded since 1924.
  • I reduced the official population figures for 1998-2015 to reflect a major annexation in 1998 that significantly increased Austin’s population. The statistical effect of that adjustment is to reduce the apparent effect of population on temperature — thus further tilting the scale in favor of AGW.
  • The official National Weather Service station moved from Mueller Airport (near I-35) to Camp Mabry (near Texas Loop 1) in 1999. I ran the regression for 1968-2015 with a dummy variable for location, but that variable is statistically insignificant.

Here’s the regression equation for 1968-2015:

T = -0.049R + 5.57E-06P + 67.8

Where,

T = average annual temperature (degrees Fahrenheit)

R = annual precipitation (inches)

P = mid-year population (adjusted, as discussed above)

The r-squared of the equation is 0.538, which is considerably better than the r-squared for a simple time trend (see the first graph below). Also, the standard error is 1.01 degrees; F = 2.96E-08; and the p-values on the variables and intercept are highly significant at 0.00313, 2.19E-08, and 7.34E-55, respectively.

Here’s a graph of actual vs. predicted temperatures:

Actual vs predicted average annual temperatures in Austin

The residuals are randomly distributed with respect to time and the estimated values of T, so there’s no question (in my mind) about having omitted a significant variable:

Average annual temperatures_residuals vs. year

Average annual temperaturs_residuals vs. estimates of T

Austin’s average annual temperature rose by 3.6 degrees F between 1968 and 2015, that is, from 66.2 degrees to 69.8 degrees. According to the regression equation, the rise in Austin’s population from 234,000 in 1968 to 853,000 (adjusted) in 2015 accounts for essentially all of the increase — 3.5 degrees of it, to be precise. That’s well within the range of urban heat-island effects for big cities, and it’s obvious that Austin became a big city between 1968 and 2015. It also agrees with the estimated effect of Austin’s population increase, as derived from the equation for North American cities in T.R. Oke’s “City Size and the Urban Heat Island.” The equation (simplified for ease of reproduction) is

T’ = 2.96 log P – 6.41

Where,

T’ = change in temperature, degrees C

P = population, holding area constant

The author reports r-squared = 0.92 and SE = 0.7 degrees C (1.26 degrees F).

The estimated UHI effect of Austin’s population growth from 1968 to 2015 is 2.99 degrees F. Given the standard error of the estimate, the estimate of 2.99 degrees isn’t significantly different from my estimate of 3.5 degrees or from the actual increase of 3.6 degrees.

I therefore dismiss the possibility that population is a proxy for the effects of CO2 emissions, which — if they significantly affect temperature (a big “if”) — do so because of their prevalence in the atmosphere, not because of their concentration in particular areas. And Austin’s hottest years occurred during the “pause” in global warming after 1998. There was no “pause” in Austin because its population continued to grow rapidly; thus:

12-month average temperatures in Austin_1903-2016

Bottom line: Austin’s temperature can be accounted for by precipitation and population. AGW will have to find another place in which to work its evil magic.

Victor Davis Hanson offers “The More Things Change, the More They Actually Don’t.” It echoes what I say in “The Fallacy of Human Progress.” Hanson opens with this:

In today’s technically sophisticated and globally connected world, we assume life has been completely reinvented. In truth, it has not changed all that much.
And he proceeds to illustrate his point (and mine).

In a different vein, there’s Francis Menton’s series about anthropogenic global warming. The latest installment is “The Greatest Scientific Fraud of All Time — Part VIII.” For my take on the subject, start with “AGW in Austin?” and check out the readings and posts listed at the bottom.

“And the Truth Shall Set You Free”

The truth contained in Drs. Lawrence Mayer and Paul McHugh’s “Sexuality and Gender” (The New Atlantis No. 50, Fall 2016) will fall on the same deaf ears as many other truths. The “party of science” is really the party of magical thinking — about many things, including economics, climate, race, war, and (most recently) “gender.”

“Gender” is the latest egregious example of seeing the world as one wishes it were, instead of the way it is. “Gender” smacks of Victorian prudery; it’s a euphemism for “sex.” But it’s more than that, because it connotes more than a mere biological fact of life; it connotes a state of mind that somehow transcends biology. (Very Zen, don’t you think?)

Among the subjects addressed by Drs. Mayer and McHugh is “gender identity” The executive summary of Part Three, which addresses that subject, gives these findings:

● The hypothesis that gender identity is an innate, fixed property of human beings that is independent of biological sex — that a person might be “a man trapped in a woman’s body” or “a woman trapped in a man’s body” — is not supported by scientific evidence.

● According to a recent estimate, about 0.6% of U.S. adults identify as a gender that does not correspond to their biological sex.

● Studies comparing the brain structures of transgender and non-transgender individuals have demonstrated weak correlations between brain structure and cross-gender identification. These correlations do not provide any evidence for a neurobiological basis for cross-gender identification.

● Compared to the general population, adults who have undergone sex-reassignment surgery continue to have a higher risk of experiencing poor mental health outcomes. One study found that, compared to controls, sex-reassigned individuals were about 5 times more likely to attempt suicide and about 19 times more likely to die by suicide.

● Children are a special case when addressing transgender issues. Only a minority of children who experience cross-gender identification will continue to do so into adolescence or adulthood.

● There is little scientific evidence for the therapeutic value of interventions that delay puberty or modify the secondary sex characteristics of adolescents, although some children may have improved psychological well-being if they are encouraged and supported in their cross-gender identification. There is no evidence that all children who express gender-atypical thoughts or behavior should be encouraged to become transgender.

Don’t get me wrong, I bear no animus toward those few persons who are truly conflicted about their sexuality. But I have no sympathy for juvenile faddishness and the unseemly (and temporarily halted) eradication of privacy in the name of “gender equality.” It’s as if time-honored codes of conduct have somehow become unnecessary and unduly discriminatory. (Where have we heard that before?)

And, as usual, the rush to remake the world in a new, trendy image won’t stop with “equality.” It will become (and has become, in some places) verboten to refer to anyone by anything but an approved label, just as it has become verboten in some places to refuse to bake a wedding cake or provide flowers for a homosexual “marriage.”

It’s easy enough for a black, a woman, or any one of a long list of “protected groups” to march into an EEOC office and file a baseless discrimination claim. It’s unsurprising that the list of protected groups now encompasses anyone who identifies as LGB or T. (What’s wrong with Q?)

What I want to know is why the EEOC and all of the other equality-enforcing agencies of government are still in business. Given the relatively small number of persons who aren’t in a protected group — namely straight, white, non-Hispanic males under the age of 40 who are neither disabled (a broad category) or veterans — it seems to me that equality has already been achieved. Except for the unprotected, of course, but only their mothers give two hoots about them (maybe).

Multiplicative Hogwash

The Economist offers an almost-balanced view of the Keynesian multiplier, starting with its inception in Keynes’s General Theory, its theoretical refinement by Alvin Hansen and Paul Samuelson, and subsequent theoretical and empirical work. This sums it up: “Decades after its conception, Keynes’s multiplier remains as relevant, and as controversial, as ever.” It’s relevant only in the sense that a lot of economists and policy-makers still believe in it. What it is is hogwash:

Further Pretensions of Knowledge

The Economist‘s second article in its series on “seminal economic ideas” is about Hyman Minsky’s theory that “booms sow the seeds of busts”:

Having grown up during the Depression, Minsky was minded to dwell on disaster. Over the years he came back to the same fundamental problem again and again. He wanted to understand why financial crises occurred. . . .

Minsky . . . developed his “financial-instability hypothesis”. It is an examination of how long stretches of prosperity sow the seeds of the next crisis, an important lens for understanding the tumult of the past decade. . . .

Minsky started with an explanation of investment. It is, in essence, an exchange of money today for money tomorrow. A firm pays now for the construction of a factory; profits from running the facility will, all going well, translate into money for it in coming years. Put crudely, money today can come from one of two sources: the firm’s own cash or that of others (for example, if the firm borrows from a bank). The balance between the two is the key question for the financial system.

Minsky distinguished between three kinds of financing. The first, which he called “hedge financing”, is the safest: firms rely on their future cashflow to repay all their borrowings. For this to work, they need to have very limited borrowings and healthy profits. The second, speculative financing, is a bit riskier: firms rely on their cashflow to repay the interest on their borrowings but must roll over their debt to repay the principal. This should be manageable as long as the economy functions smoothly, but a downturn could cause distress. The third, Ponzi financing, is the most dangerous. Cashflow covers neither principal nor interest; firms are betting only that the underlying asset will appreciate by enough to cover their liabilities. If that fails to happen, they will be left exposed.

Economies dominated by hedge financing—that is, those with strong cashflows and low debt levels—are the most stable. When speculative and, especially, Ponzi financing come to the fore, financial systems are more vulnerable. If asset values start to fall, either because of monetary tightening or some external shock, the most overstretched firms will be forced to sell their positions. This further undermines asset values, causing pain for even more firms. They could avoid this trouble by restricting themselves to hedge financing. But over time, particularly when the economy is in fine fettle, the temptation to take on debt is irresistible. When growth looks assured, why not borrow more? Banks add to the dynamic, lowering their credit standards the longer booms last. If defaults are minimal, why not lend more? Minsky’s conclusion was unsettling. Economic stability breeds instability. Periods of prosperity give way to financial fragility. . . .

[A]s an outsider in the sometimes cloistered world of economics, Minsky’s influence was, until recently, limited. Investors were faster than professors to latch onto his views. More than anyone else it was Paul McCulley of PIMCO, a fund-management group, who popularised his ideas. He coined the term “Minsky moment” to describe a situation when debt levels reach breaking-point and asset prices across the board start plunging. Mr McCulley initially used the term in explaining the Russian financial crisis of 1998. Since the global turmoil of 2008, it has become ubiquitous. For investment analysts and fund managers, a “Minsky moment” is now virtually synonymous with a financial crisis. . . .

. . . In a speech in 2009, before she became head of the Federal Reserve, Janet Yellen said Minsky’s work had “become required reading”. In a 2013 speech, made while he was governor of the Bank of England, Mervyn King agreed with Minsky’s view that stability in credit markets leads to exuberance and eventually to instability. Mark Carney, Lord King’s successor, has referred to Minsky moments on at least two occasions.Will the moment last? Minsky’s own theory suggests it will eventually peter out. Economic growth is still shaky and the scars of the global financial crisis visible. In the Minskyan trajectory, this is when firms and banks are at their most cautious, wary of repeating past mistakes and determined to fortify their balance-sheets. But in time, memories of the 2008 turmoil will dim. Firms will again race to expand, banks to fund them and regulators to loosen constraints. The warnings of Minsky will fade away. The further we move on from the last crisis, the less we want to hear from those who see another one coming.

I am left with this question: Is the Minskyan trajectory a bad thing or a good thing? Is there a better, feasible way to finance economic growth? Or is the alternative some kind of government-enforced algorithm in which one-size-fits-all-regulation fosters hyper-bubbles (as with the directive to lend more to poor, minority mortgagors) or hypo-bubbles (in which rising investment is stifled long before it becomes a bubble).

Government doesn’t have a good track record when it comes to fine-tuning the economy. It’s true that the economy has been somewhat more stable since the creation of the Federal Reserve in 1913. But the price of stability is high; namely, it is inversely related to long-run economic growth. And the two deepest economic downturns in America’s history — the Great Depression and the Great Recession — happened on the Fed’s watch, and can be blamed (in part, at least) on the Fed.

Economics can be a powerfully descriptive discipline. But its power to describe is far from infallible, as Arnold Kling shows in his must-read tome, Specialization and Trade: A Re-introduction to Economics. Among many things, Kling explains why the Keynesian multiplier — the hoariest of fine-tuning ideas — is a terrible idea. (I heartily agree with Kling.)

Even if economics were an infallibly descriptive discipline, it shouldn’t be taken as an infallibly prescriptive one. Friedrich Hayek put it this way in his Nobel Prize Lecture, “The Pretence of Knowledge“:

It is true that . . . systems of equations describing the pattern of a market equilibrium are so framed that if we were able to fill in all the blanks of the abstract formulae, i.e. if we knew all the parameters of these equations, we could calculate the prices and quantities of all commodities and services sold. But, as Vilfredo Pareto, one of the founders of this theory, clearly stated, its purpose cannot be “to arrive at a numerical calculation of prices”, because, as he said, it would be “absurd” to assume that we could ascertain all the data. . . .  I sometimes wish that our mathematical economists would take this to heart. I must confess that I still doubt whether their search for measurable magnitudes has made significant contributions to our theoretical understanding of economic phenomena – as distinct from their value as a description of particular situations. Nor am I prepared to accept the excuse that this branch of research is still very young: Sir William Petty, the founder of econometrics, was after all a somewhat senior colleague of Sir Isaac Newton in the Royal Society!

The chief point we must remember is that the great and rapid advance of the physical sciences took place in fields where it proved that explanation and prediction could be based on laws which accounted for the observed phenomena as functions of comparatively few variables – either particular facts or relative frequencies of events. . . .  A theory of essentially complex phenomena must refer to a large number of particular facts; and to derive a prediction from it, or to test it, we have to ascertain all these particular facts. Once we succeeded in this there should be no particular difficulty about deriving testable predictions – with the help of modern computers it should be easy enough to insert these data into the appropriate blanks of the theoretical formulae and to derive a prediction. The real difficulty, to the solution of which science has little to contribute, and which is sometimes indeed insoluble, consists in the ascertainment of the particular facts. . . .

. . . To act on the belief that we possess the knowledge and the power which enable us to shape the processes of society entirely to our liking, knowledge which in fact we do not possess, is likely to make us do much harm. In the physical sciences there may be little objection to trying to do the impossible; one might even feel that one ought not to discourage the over-confident because their experiments may after all produce some new insights. But in the social field the erroneous belief that the exercise of some power would have beneficial consequences is likely to lead to a new power to coerce other men being conferred on some authority. Even if such power is not in itself bad, its exercise is likely to impede the functioning of those spontaneous ordering forces by which, without understanding them, man is in fact so largely assisted in the pursuit of his aims. We are only beginning to understand on how subtle a communication system the functioning of an advanced industrial society is based – a communications system which we call the market and which turns out to be a more efficient mechanism for digesting dispersed information than any that man has deliberately designed.

If man is not to do more harm than good in his efforts to improve the social order, he will have to learn that in this, as in all other fields where essential complexity of an organized kind prevails, he cannot acquire the full knowledge which would make mastery of the events possible. He will therefore have to use what knowledge he can achieve, not to shape the results as the craftsman shapes his handiwork, but rather to cultivate a growth by providing the appropriate environment, in the manner in which the gardener does this for his plants. There is danger in the exuberant feeling of ever growing power which the advance of the physical sciences has engendered and which tempts man to try, “dizzy with success”, to use a characteristic phrase of early communism, to subject not only our natural but also our human environment to the control of a human will. The recognition of the insuperable limits to his knowledge ought indeed to teach the student of society a lesson of humility which should guard him against becoming an accomplice in men’s fatal striving to control society – a striving which makes him not only a tyrant over his fellows, but which may well make him the destroyer of a civilization which no brain has designed but which has grown from the free efforts of millions of individuals.

(This post offers more on this subject of the limitations of knowledge, and the implications for economic policy.)

The ability to describe a phenomenon in a general way is far from knowing how to improve on it. In fact, the ability to describe a phenomenon in a general way says nothing about whether it can be improved on. Such things as investment bubbles, market failure, and winners and losers from trade are the normative judgments of observers who simply don’t like what they see and believe (mistakenly) that they know how to “make things right.”

The Precautionary Principle and Pascal’s Wager

Reduced to its essence, the precautionary principle (PP) is this: Avert calamity regardless of the cost of doing so.

The thinking person, as opposed the the extreme environmentalist or global-warming zealot, will immediately and carefully pose these questions about the PP: What, specifically, is the calamity to be averted? How might it be averted? With what degree of certainty? What are the opportunity and monetary costs of the options?

Take death, for example. Most persons who are in good health (and even many who are in declining health) consider death to be a calamity. So, too, do their loved ones (usually). How, then, might death be averted, with what degree of certainty, and at what cost?

Death can be averted only temporarily. That is, death often can sometimes be postponed, but never defeated. So the question is how can it be postponed, and at what cost. Let’s take an extreme case of a man dying of a virulent cancer (confirmed by extensive tests and procedures) for which there is no known treatment, other than palliative care. What good will it do that man (or his heirs) to spend his fortune in search of cure for his disease? He will almost certainly die before a possible cure is identified and can be supplied to him. But in funding the search for a cure he would have followed the PP by doing his utmost to avoid the calamity of death, without regard for the calamity thereby visited upon upon his heirs.

In sum, the PP shouldn’t be followed in cases where:

  • there is nothing that human beings can do to avert the calamity, or
  • the cost of ameliorating the calamity is itself calamitous.

Extreme environmentalists and global-warming zealots are guilty of sub-optimizing. They focus on particular calamities, not on the big picture of human flourishing. Take global warming. It has been said many times that warming has many advantages, such as a longer growing season and a lower death rate (cold is a bigger killer than heat). It has also been shown that warming hasn’t been occurring as fast as projected. The over-estimation of warming is probably due to (a) overstatement of the effects of CO2 emissions on temperatures and (b) inadequate modeling that omits key factors. But the zealots remain undeterred by such considerations.

The only thing that’s saving humanity from total impoverishment at the hands of global-warming zealots is the ridiculously high cost of (probably futile) efforts to combat global warming. Shutting down coal mines is bad enough, though tolerable given the advances that have been made in the extraction of natural gas and oil. But there is little taste (except among well-fed elites) for shutting down factories, forcing everyone to drive battery-powered cars, shifting to high-cost and unreliable sources of energy (solar, wind, and hydro), forcing people to live in densely populated cities, and so on. And if all of those things were to happen, what difference would it make? Almost none.

Moreover, there is nothing unusual about the rising temperatures of recent decades, neither in rapidity nor level. As Bob Tisdale observes, during three global warming periods — 1916-1946, 1964-1993, and 1986-2015 —

there were similar observed changes in global surface temperatures. It’s tough to claim that the recent global warming is unprecedented when surface temperatures rose at a comparable rate over a 30-year timespan that ended about 70 years ago.

Second, climate models are not simulating climate as it existed in the past or present.  The model mean of the climate models produced for the IPCC’s 5th Assessment Report simulates observed warming trends for one of the three periods shown in this post. Specifically, during the three global warming periods discussed in this post, climate models simulated three very different rates of warming (+0.050 deg C/decade for 1916-1946, +0.155 deg C/decade for 1964-1993, and +0.255 deg C/decade for 1986-2015), yet the data from GISS indicated the warming trends were very similar at +0.16 deg C/decade and +0.166 deg C/decade. If climate models can’t simulate global surface temperatures in the past or present, why should anyone have any confidence in their prognostications of future surface temperatures?

Third, the models’ failure to simulate the rate of the observed early 20th Century warming from 1916-1945 indicates that there are naturally occurring processes that can cause global surfaces to warm over multi-decadal periods above and beyond the computer-simulated warming from the forcings used to drive the climate models [emphasis added].  That of course raises the question, how much of the recent warming is also natural?

Fourth, for the most-recent 30-year period (1986-2015), climate models are overestimating the warming by a noticeable amount. This, along with their failure to simulate warming from 1916-1945, suggests climate models are too sensitive to greenhouse gases and that their projections of future global warming are too high.

Fifth, logically, the fact that the models seem to simulate the correct global-warming rate for one of the three periods discussed [1964-1993] does not mean the climate models are performing properly during the one “good” period.

Despite such reasonableness, global-warming-zealot proponents of the PP are not to be deflected. For theirs is a religion, which seems to take Pascal’s wager seriously. Here’s Robert Tracinski on the subject:

Do you freaking love science? Then you might be a big enough sucker to fall for a claim like this one: “Across the span of their lives, the average American is more than five times likelier to die during a human-extinction event than in a car crash.” Which was actually made by an environmentalist group called the Global Challenges Foundation and reported with a straight face in The Atlantic….

There is something that sounded familiar to me about this argument, and I realized that it borrows the basic form of Pascal’s Wager, an old and spectacularly unconvincing argument for belief in God. (Go here if you want to give the idea more thought than it probably deserves.) Blaise Pascal’s argument was that even if the existence of God is only a very small probability, the consequences are so spectacularly huge — eternal life if you follow the rules, eternal punishment if you don’t — that it makes even a very small probability seem overwhelmingly important. In effect, Pascal realized that you can make anything look big if you multiply it by infinity. Similarly, this new environmentalist argument assumes that you can make anything look big if you multiply it by extinction….

If Pascal’s probabilistic argument works for Christianity, then it also works for Islam, or for secular versions like Roko’s Basilisk. (And yes, an “all-seeing artificial intelligence” is included in this report as a catastrophic possibility, which gives you an idea of how seriously you should take it.) Or it works for global warming, which is exactly how it’s being used here.

Pascal was a great mathematician, but this was an awful abuse of the nascent science of probabilities. (I suspect it’s no great shakes from a religious perspective, either.) First of all, a “probability” is not just anything that you sort of think might happen. Imagination and speculation are not probability. In any mathematical or scientific sense of the word, a probability is something for which you have a real basis to measure its likelihood. Saying you are “95 percent certain” about a scientific theory, as global warming alarmists are apt to do, might make for an eye-catching turn of phrase in press headlines. But it is not an actual number that measures something.

Indeed.

Tracinski later hits a verbal home run with this:

This kind of Pascal’s-Wager-for-global-warming is part of a larger environmentalist program: a perverse attempt to take our sense of the actual risks and benefits for human life and turn it upside down.

If we’re concerned about the actual dangers to human life, we don’t have to assume a bunch of bizarre probabilities. The big dangers are known quantities: poverty, squalor, disease, famine, dictatorship, war. And the solutions are also known quantities: technology, industrialization, economic growth, freedom.

Global-warming zealots are usually leftists, and leftists claim to be upholders of science. Yet they cling to two anti-scientific dogmas: the precautionary principle and Pascal’s Wager. As Tracinski says, “global warming has become a religion with a veneer of science.”

Immigration and Intelligence

I haven’t written about intelligence since April 18, 2015 (here, third item). What’s on my mind now? This:

1. Immigrants to the U.S. are overwhelmingly poor and possibly (but not necessarily) below-average in intelligence.

2. The availability of immigrants seeking employment is a boon to entrepreneurs. Investments in capital (often modest ones such as lawn mowers and chain saws) can be turned into gainful employment for immigrants and profits for entrepreneurs.

3. The employment of immigrants is also a boon to American consumers, who are able to obtain some things more cheaply and some things that they might otherwise not be able to afford (e.g., fresh fruit, maid services, yard work).

4. Consumers should be indifferent about the origin of the labor that benefits them.

5. Taxpayers should care about the origin of labor only to the extent that immigration drives up the taxes because of state support for immigrants (e.g., schooling, medical care, welfare programs where citizenship isn’t a prerequisite).

6. Each taxpayer is also a consumer, and each taxpayer is therefore in a different position with respect to the net benefits (or costs) of immigration. But every consumer-citizen is likely to benefit to some degree because of immigration, though the benefit may not offset the rise in every consumer-citizen’s taxes.

7. Low-skilled Americans who have opted for the dole have no stake in the matter of immigration. If some low-skilled Americans lose jobs that they might otherwise have held, they aren’t “losers” any more than the wagon-makers who lost their jobs when automobiles come along. Voluntary economic change doesn’t have winners and losers — it takes arbitrary government interventions (e.g., minimum-wage laws) to create them.

8. Yes, government allows immigration, but the original intervention that created winners and losers is the one that restrained immigration. If it’s all right for a piece of fruit to move from Mexico to Texas, why isn’t it all right for a worker to move from Mexico to Texas? If it’s all right for a Californian to move to Texas, it is definitely all right for a Mexican to move to Texas.

9. So the only question is whether immigration imposes net costs on some consumers who are also taxpayers. And it’s an issue only because of government programs that allow immigrants to impose costs on taxpayers.

10. The real issue, for me, isn’t immigration, it’s government interventions that may encourage immigration (at a rate higher than the “natural” one) and subsidize immigrants. As usual, government is the problem, not the solution.

What does this have to do with intelligence? This post was spurred by a recent one at West Hunter by Gregory Cochran, “Our Dumb World.” Cochran’s post, combined with another one of his to which he links, can be read as follows:

  • There’s a strong link between the average IQ of a nation and its economic success. (True.)
  • Some things have skewed the relationship (e.g., the imposition of Communism), but the link is there nonetheless.
  • Mass migration from low-IQ countries (presumably Mexico and other Central American nations) to a country with a higher average IQ (e.g., the United States) will reduce the average IQ of the receiving country and therefore harm it economically.

I don’t buy it. For one thing, immigration — even immigration by low-skilled workers with (perhaps) below-average intelligence — can be a boon to the residents of the receiving country, as discussed above. For another thing:

Low-IQ immigrants do not reduce the productivity of high-IQ natives – any more than short immigrants reduce the height of tall natives. (See here for further discussion).

To repeat myself, the real issue is whether government action causes immigrants to impose burdens on natives that wouldn’t be imposed in the absence of government action. And to be clear, government action is any action that results in a rate of immigration which is higher or lower than would occur in the absence of that action (e.g., immigration quotas, implicit or explicit promises of government aid to indigent immigrants).

What about the political and cultural effects of massive immigration from south of the border? I am at the point of declaring that it doesn’t matter. The welfare state is so firmly entrenched in America that I really don’t expect it to be uprooted, except by non-electoral means. Mass culture is already so degenerate that it’s hard to see what could make it worse. And I have no reason to believe that, in general, Hispanics are more vulgar than American Anglos. (Just look at the prime-time TV lineup.) Those of us who prefer high culture can enjoy it without mingling with the hoi polloi.

I have been for years an opponent of illegal immigration. I am on the verge of changing my mind — something of which I am capable. My main reservation now has to do with the effect of mass immigration on crime, about which I can only offer conjectures.

The Technocratic Illusion

Kevin Williamson explodes it:

Professor [Neil deGrasse] Tyson, who may be the dumbest smart person on Twitter, yesterday wrote that what the world really needs is a new kind of virtual state — he wants to call it “Rationalia” — with a one-sentence constitution: “All policy shall be based on the weight of evidence.” This schoolboy nonsense came under withering and much-deserved derision. Conservatives, who always have the French Revolution in their thoughts, reminded him that this already has been tried, and that the results are known in the history books as “the Terror.” Writing with a great deal of reserve in Popular Science, Kelsey D. Atherton notes:

Rationalia puts a burden on science that it cannot bear: to work, it must be immune to the passions of the day, promising an objective world and objective truth that will triumph over obstacles.

That’s true enough, but it shortchanges the scientific objection to Tyson’s Rationalia pipe dream, which is that it implicitly presupposes quantities and types of knowledge that are not, even in principle, available, even if the scientists in question were the dispassionate truth-seekers of Atherton’s ideal.

But will the technocrats be deterred from trying to make the world more perfect, thus making it more hellish? No, they will not be deterred. The world is full of biased know-it-alls — many of whom claim to be scientists (e.g., Neil deGrasse Tyson).

The last word goes to G. Shane Morris:

Tyson … has a philosophy, whether he realizes it or not. It’s called “scientism,” the belief that science is the only valid source of knowledge. The rule-by-self-identified-experts he envisions for the happy land of Rationalia is scientism’s logical outcome. But when you insist that facts and evidence speak for themselves, it has a funny way of silencing everyone else. As one intrepid Twitter user replied to Tyson’s initial tweet, “Convenient how the ‘evidence’ always seems to line up with Tyson’s personal beliefs.”

The real problem, of course, is that Rationalia doesn’t take into account the fallenness of human nature, or the fact that we all approach reality with a certain set of assumptions. If we’re to build a new country based on rationality, the question is simply, “Whose rationality?” I certainly don’t want it to be from someone who’s blind to his own biases, to the flaws of science, and to other people’s perspectives.

A Rather Normal Distribution

I found a rather normal distribution from the real world — if you consider major-league baseball to be part of the real world. In a recent post I explained how I normalized batting statistics for the 1901-2015 seasons, and displayed the top-25 single-season batting averages, slugging percentages, and on-base-plus-slugging percentages after normalization.

I have since discovered that the normalized single-season batting averages for 14,067 player-seasons bear a strong resemblance to a textbook normal distribution:

Distribution of normalized single-season batting averrages

How close is this to a textbook normal distribution? Rather close, as measured by the percentage of observations that are within 1, 2, 3, and 4 standard deviations from the mean:

Distribution of normalized single-season batting averrages_table

Ty Cobb not only compiled the highest single-season average (4.53 SD above the mean) but 5 of the 12 single-season averages more than 4 SD above the mean:

Ty Cobb's normalized single-season batting_SD from mean

Cobb’s superlative performances in the 13-season span from 1907 through 1919 resulted in 12 American League batting championships. (The unofficial number has been reduced to 11 because it was later found that Cobb actually lost the 1910 title by a whisker — .3834 to Napoleon Lajoie’s .3841.)

Cobb’s normalized batting average for his worst full season (1924) is better than 70 percent of the 14,067 batting averages compiled by full-time players in the 115 years from 1901 through 2015. And getting on base was only part of what made Cobb the greatest player of all time.

Understanding Probability: Pascal’s Wager and Catastrophic Global Warming

I love it when someone issues a well-constructed argument that supports my position on an issue. (It happens often, of course.) The latest case in point is a post by Robert Tracinski, “Pascal’s Wager for the Global Warming Religion” (The Federalist, May 3, 2016). Tracinski address this claim by some global-warming zealots:

Across the span of their lives, the average American is more than five times likelier to die during a human-extinction event than in a car crash.

There’s a lot more wrong with that statement than the egregious use of plural (“their lives”) and singular (“is”) constructions with respect to “the average American” (singular). Here’s what’s really wrong, in Tracinski’s words:

There is something that sounded familiar to me about this argument, and I realized that it borrows the basic form of Pascal’s Wager, an old and spectacularly unconvincing argument for belief in God. (Go here if you want to give the idea more thought than it probably deserves.)

Repeat after me:

A probability is a statement about a very large number of like events, each of which has an unpredictable (random) outcome. Probability, properly understood, says nothing about the outcome of an individual event. It certainly says nothing about what will happen next.

My War on the Misuse of Probability

Ty Cobb and the State of Science

This post was inspired by “Layman’s Guide to Understanding Scientific Research” at bluebird of bitterness.

The thing about history is that it’s chock full of lies. Well, a lot of the lies are just incomplete statements of the truth. Think of history as an artificially smooth surface, where gaps in knowledge have been filled by assumptions and guesses, and where facts that don’t match the surrounding terrain have been sanded down. Charles Leershen offers an excellent example of the lies that became “history” in his essay “Who Was Ty Cobb? The History We Know That’s Wrong.” (I’m now reading the book on which the essay is based, and it tells the same tale, at length.)

Science is much like history in its illusory certainty. Stand back from things far enough and you see a smooth, mathematical relationship. Look closer, however, and you find rough patches. A classic example is found in physics, where the big picture of general relativity doesn’t mesh with the small picture of quantum mechanics.

Science is based on guesses, also known as hypotheses. The guesses are usually informed by observation, but they are guesses nonetheless. Even when a guess has been lent credence by tests and observations, it only becomes a theory — a working model of a limited aspect of physical reality. A theory is never proven; it can only be disproved.

Science, in other words, is never “settled.” Napoleon is supposed to have said “What is history but a fable agreed upon?” It seems, increasingly, that so-called scientific facts are nothing but a fable that some agree upon because they wish to use those “facts” as a weapon with which to advance their careers and political agendas. Or they simply wish to align themselves with the majority, just as Barack Obama’s popularity soared (for a few months) after he was re-elected.

My War on the Misuse of Probability

In the preceding post I say that “the problem with history is that the future isn’t part of it.” That is subtle criticism of the too-frequent practice of attributing a probability to the occurrence of a future event — especially a unique event, such as a war here or a terrorist attack there.

A probability is a statement about a very large number of like events, each of which has an unpredictable (random) outcome. Probability, properly understood, says nothing about the outcome of an individual event. It certainly says nothing about what will happen next.

A fair coin comes up heads with a probability of 0.5, and comes up tails with the same probability. But those aren’t statements about the outcome of the next coin toss. No, they’re statements about the approximate frequencies of the occurrence of heads and tails in a large number of tosses. The next coin toss will eventuate in heads or tails, but not 0.5 heads and 0.5 tails (except in the rare and unpredictable case of a coin landing on edge and staying there).

There’s a vast gap between routine processes of the kind to which probabilities attach — coin tosses, for example — and the complexities of human activity. Human activity is too complex and dependent on intentions and willful actions to be characterized (properly) by statements about the probability of this or that action.

It is fatuous to say, for example, that a war on the scale of World War II is improbable because such a war has occurred only once in human history. By that reasoning, one could have said confidently in 1938 that a war on the scale of World War II could never occur because there had been no such war in human history.

(Inspired by Bryan Caplan’s fatuous post, “So Far.”)

Time and Reality

There’s an argument that time is an illusion. There’s nothing but the present — the now — or, rather, an infinite number of nows. In the conventional view, one now succeeds another, which creates the illusion of the passage of time. In the view of some physicists, all nows exist at once, and we merely perceive them sequentially (or so it seems).

A problem with the conventional view is that not everyone perceives the same now, according to Einstein’s special theory of relativity. A problem with the view that all nows exist at once (known as the many-worlds view), is that it’s purely a mathematical concoction.

Oh, wait, that’s also true of the special theory of relativity, though the underpinnings of the theory have been proven experimentally. But, as I understand it, the Lorentz transformation enables one to reconcile the various nows of special relativity, that is, to stand in the place of an omniscient observer. So, in effect, there really is a now — or an infinite series of nows, perceived sequentially.

This leads to the question of what distinguishes one now from another now. The answer is change. If things didn’t change, there would be only a now, not an infinite series of them.

What happens between one now and the next now? Change, not the passage of time. What we think of as the passage of time is really an artifact of change.

Time is really nothing more than the counting of events that supposedly occur at set intervals — the “ticking” of an atomic clock, for example. I say supposedly because there’s no absolute measure of time against which one can calibrate the “ticking” of an atomic clock, or any other kind of clock. (See Einstein’s special theory of relativity.)

In summary: Clocks don’t measure time. Clocks merely change (e.g., “tick”) at supposedly regular intervals, and those intervals are used in the representation of other things, such as the speed of an automobile or the duration of a 100-yard dash.

Time is an illusion. Change is real. But change in what — of what does reality consist?

There are two basic views of reality. One of them, according to Bishop Berkeley and his followers, is that the only reality is that which goes on in one’s own mind. The other basic view, held by most people (including most scientists), is that there is an objective reality out there, beyond the confines one’s mind. How, after all, can so many people agree about the existence of certain things (e.g., Cleveland) unless there’s something out there?

Over the ages, scientists have been able to describe objective reality in ever-increasing, ever-minute detail. But what is it? What is the stuff of which it consists? No one knows or is likely ever to know. All we know is that stuff changes, and those changes give rise to what we call time.

Pardon my seriousness. Someone must have put something in my soup.

 

 

 

 

A Summing Up

I started blogging in the late 1990s with a home page that I dubbed Liberty Corner (reconstructed here). I maintained the home page until 2000. When the urge to resume blogging became irresistible in 2004, I created the Blogspot version of Liberty Corner, where I blogged until May 2008.

My weariness with “serious” blogging led to the creation of Americana, Etc., “A blog about baseball, history, humor, language, literature, movies, music, nature, nostalgia, philosophy, psychology, and other (mostly) apolitical subjects.” I began that blog in July 2008 and posted there sporadically until September 2013.

But I couldn’t resist commenting on political, economic, and social issues, so I established Politics & Prosperity in February 2009. My substantive outpourings ebbed and flowed, until August 2015, when I hit a wall.

Now, almost two decades and more than 3,000 posts since my blogging debut, I am taking another rest from blogging — perhaps a permanent rest.

Instead of writing a valedictory essay, I chose what I consider to be the best of my blogging, and assigned each of my choices to one of fifteen broad topics. (Many of the selections belong under more than one heading, but I avoided repetition for the sake of brevity.) You may jump directly to any of the fifteen topics by clicking on one of these links:

Posts are listed in chronological order under each heading. If you are looking for a post on a particular subject, begin with the more recent posts and work your way backward in time, by moving up the list or using the “related posts” links that are included in most of my posts.

Your explorations may lead you to posts that no longer represent my views. This is especially the case with respect to John Stuart Mill’s “harm principle,” which figures prominently in my early dissertations on libertarianism, but which I have come to see as shallow and lacking in prescriptive power. Thus my belief that true libertarianism is traditional conservatism. (For more, see “On Liberty and Libertarianism” in the sidebar and many of the posts under “X. Libertarianism and Other Political Philosophies.”)

The following list of “bests” comprises about 700 entries, which is less than a fourth of my blogging output. I also commend to you my “Not-So-Random Thoughts” series — I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, and XVI — and “The Tenor of the Times.”

Victor Davis Hanson writes:

This descent into the Dark Ages will not end well. It never has in the past. [“Building the New Dark-Age Mind,” Works and Days, June 8, 2015]

Hamson’s chronicle of political correctness and doublespeak echoes one theme of my post, “1963: The Year Zero.”

*     *     *

Timothy Taylor does the two-handed economist act:

It may be that the question of “does inequality slow down economic growth” is too broad and diffuse to be useful. Instead, those of us who care about both the rise in inequality and the slowdown in economic growth should be looking for policies to address both goals, without presuming that substantial overlap will always occur between them. [“Does Inequality Reduce Economic Growth: A Skeptical View,” The Conversible Economist, May 29, 2015]

The short answer to the question “Does inequality reduce growth?” is no. See my post “Income Inequality and Economic Growth.” Further, even if inequality does reduce growth, the idea of reducing inequality (through income redistribution, say) to foster growth is utilitarian and therefore morally egregious. (See “Utilitarianism vs. Liberty.”)

*     *     *

In “Diminishing Marginal Utility and the Redistributive Urge” I write:

[L]eftists who deign to offer an economic justification for redistribution usually fall back on the assumption of the diminishing marginal utility (DMU) of income and wealth. In doing so, they commit (at least) four errors.

The first error is the fallacy of misplaced concreteness which is found in the notion of utility. Have you ever been able to measure your own state of happiness? I mean measure it, not just say that you’re feeling happier today than you were when your pet dog died. It’s an impossible task, isn’t it? If you can’t measure your own happiness, how can you (or anyone) presume to measure and aggregate the happiness of millions or billions of individual human beings? It can’t be done.

Which brings me to the second error, which is an error of arrogance. Given the impossibility of measuring one person’s happiness, and the consequent impossibility of measuring and comparing the happiness of many persons, it is pure arrogance to insist that “society” would be better off if X amount of income or wealth were transferred from Group A to Group B….

The third error lies in the implicit assumption embedded in the idea of DMU. The assumption is that as one’s income or wealth rises one continues to consume the same goods and services, but more of them….

All of that notwithstanding, the committed believer in DMU will shrug and say that at some point DMU must set in. Which leads me to the fourth error, which is an error of introspection….  [If over the years] your real income has risen by a factor of two or three or more — and if you haven’t messed up your personal life (which is another matter) — you’re probably incalculably happier than when you were just able to pay your bills. And you’re especially happy if you put aside a good chunk of money for your retirement, the anticipation and enjoyment of which adds a degree of utility (such a prosaic word) that was probably beyond imagining when you were in your twenties, thirties, and forties.

Robert Murphy agrees:

[T]he problem comes in when people sometimes try to use the concept of DMU to justify government income redistribution. Specifically, the argument is that (say) the billionth dollar to Bill Gates has hardly any marginal utility, while the 10th dollar to a homeless man carries enormous marginal utility. So clearly–the argument goes–taking a dollar from Bill Gates and giving it to a homeless man raises “total social utility.”

There are several serious problems with this type of claim. Most obvious, even if we thought it made sense to attribute units of utility to individuals, there is no reason to suppose we could compare them across individuals. For example, even if we thought a rich man had units of utility–akin to the units of his body temperature–and that the units declined with more money, and likewise for a poor person, nonetheless we have no way of placing the two types of units on the same scale….

In any event, this is all a moot point regarding the original question of interpersonal utility comparisons. Even if we thought individuals had cardinal utilities, it wouldn’t follow that redistribution would raise total social utility.

Even if we retreat to the everyday usage of terms, it still doesn’t follow as a general rule that rich people get less happiness from a marginal dollar than a poor person. There are many people, especially in the financial sector, whose self-esteem is directly tied to their earnings. And as the photo indicates, Scrooge McDuck really seems to enjoy money. Taking gold coins from Scrooge and giving them to a poor monk would not necessarily increase happiness, even in the everyday psychological sense. [“Can We Compare People’s Utilities?,” Mises Canada, May 22, 2015]

See also David Henderson’s “Murphy on Interpersonal Utility Comparisons” (EconLog, May 22, 2015) and Henderson’s earlier posts on the subject, to which he links. Finally, see my comment on an earlier post by Henderson, in which he touches on the related issue of cost-benefit analysis.

*     *     *

Here’s a slice of what Robert Tracinski has to say about “reform conservatism”:

The key premise of this non-reforming “reform conservatism” is the idea that it’s impossible to really touch the welfare state. We might be able to alter its incentives and improve its clanking machinery, but only if we loudly assure everyone that we love it and want to keep it forever.

And there’s the problem. Not only is this defeatist at its core, abandoning the cause of small government at the outset, but it fails to address the most important problem facing the country.

“Reform conservatism” is an answer to the question: how can we promote the goal of freedom and small government—without posing any outright challenge to the welfare state? The answer: you can’t. All you can do is tinker around the edges of Leviathan. And ultimately, it won’t make much difference, because it will all be overwelmed in the coming disaster. [“Reform Conservatism Is an Answer to the Wrong Question,” The Federalist, May 22, 2015]

Further, as I observe in “How to Eradicate the Welfare State, and How Not to Do It,” the offerings of “reform conservatives”

may seem like reasonable compromises with the left’s radical positions. But they are reasonable compromises only if you believe that the left wouldn’t strive vigorously to undo them and continue the nation’s march toward full-blown state socialism. That’s the way leftists work. They take what they’re given and then come back for more, lying and worse all the way.

See also Arnold Kling’s “Reason Roundtable on Reform Conservatism” (askblog, May 22, 2015) and follow the links therein.

I’ll end this installment with a look at science and the anti-scientific belief in catastrophic anthropogenic global warming.

Here’s Philip Ball in “The Trouble With Scientists“:

It’s likely that some researchers are consciously cherry-picking data to get their work published. And some of the problems surely lie with journal publication policies. But the problems of false findings often begin with researchers unwittingly fooling themselves: they fall prey to cognitive biases, common modes of thinking that lure us toward wrong but convenient or attractive conclusions. “Seeing the reproducibility rates in psychology and other empirical science, we can safely say that something is not working out the way it should,” says Susann Fiedler, a behavioral economist at the Max Planck Institute for Research on Collective Goods in Bonn, Germany. “Cognitive biases might be one reason for that.”

Psychologist Brian Nosek of the University of Virginia says that the most common and problematic bias in science is “motivated reasoning”: We interpret observations to fit a particular idea. Psychologists have shown that “most of our reasoning is in fact rationalization,” he says. In other words, we have already made the decision about what to do or to think, and our “explanation” of our reasoning is really a justification for doing what we wanted to do—or to believe—anyway. Science is of course meant to be more objective and skeptical than everyday thought—but how much is it, really?

Whereas the falsification model of the scientific method championed by philosopher Karl Popper posits that the scientist looks for ways to test and falsify her theories—to ask “How am I wrong?”—Nosek says that scientists usually ask instead “How am I right?” (or equally, to ask “How are you wrong?”). When facts come up that suggest we might, in fact, not be right after all, we are inclined to dismiss them as irrelevant, if not indeed mistaken….

Given that science has uncovered a dizzying variety of cognitive biases, the relative neglect of their consequences within science itself is peculiar. “I was aware of biases in humans at large,” says [Chris] Hartgerink [of Tilburg University in the Netherlands], “but when I first ‘learned’ that they also apply to scientists, I was somewhat amazed, even though it is so obvious.”…

One of the reasons the science literature gets skewed is that journals are much more likely to publish positive than negative results: It’s easier to say something is true than to say it’s wrong. Journal referees might be inclined to reject negative results as too boring, and researchers currently get little credit or status, from funders or departments, from such findings. “If you do 20 experiments, one of them is likely to have a publishable result,” [Ivan] Oransky and [Adam] Marcus [who run the service Retraction Watch] write. “But only publishing that result doesn’t make your findings valid. In fact it’s quite the opposite.”9 [Nautilus, May 14, 2015]

Zoom to AGW. Robert Tracinski assesses the most recent bit of confirmation bias:

A lot of us having been pointing out one of the big problems with the global warming theory: a long plateau in global temperatures since about 1998. Most significantly, this leveling off was not predicted by the theory, and observed temperatures have been below the lowest end of the range predicted by all of the computerized climate models….

Why, change the data, of course!

Hence a blockbuster new report: a new analysis of temperature data since 1998 “adjusts” the numbers and magically finds that there was no plateau after all. The warming just continued….

How convenient.

It’s so convenient that they’re signaling for everyone else to get on board….

This is going to be the new party line. “Hiatus”? What hiatus? Who are you going to believe, our adjustments or your lying thermometers?…

The new adjustments are suspiciously convenient, of course. Anyone who is touting a theory that isn’t being borne out by the evidence and suddenly tells you he’s analyzed the data and by golly, what do you know, suddenly it does support his theory—well, he should be met with more than a little skepticism.

If we look, we find some big problems. The most important data adjustments by far are in ocean temperature measurements. But anyone who has been following this debate will notice something about the time period for which the adjustments were made. This is a time in which the measurement of ocean temperatures has vastly improved in coverage and accuracy as a whole new set of scientific buoys has come online. So why would this data need such drastic “correcting”?

As climatologist Judith Curry puts it:

The greatest changes in the new NOAA surface temperature analysis is to the ocean temperatures since 1998. This seems rather ironic, since this is the period where there is the greatest coverage of data with the highest quality of measurements–ARGO buoys and satellites don’t show a warming trend. Nevertheless, the NOAA team finds a substantial increase in the ocean surface temperature anomaly trend since 1998.

….

I realize the warmists are desperate, but they might not have thought through the overall effect of this new “adjustment” push. We’ve been told to take very, very seriously the objective data showing global warming is real and is happening—and then they announce that the data has been totally changed post hoc. This is meant to shore up the theory, but it actually calls the data into question….

All of this fits into a wider pattern: the global warming theory has been awful at making predictions about the data ahead of time. But it has been great at going backward, retroactively reinterpreting the data and retrofitting the theory to mesh with it. A line I saw from one commenter, I can’t remember where, has been rattling around in my head: “once again, the theory that predicts nothing explains everything.” [“Global Warming: The Theory That Predicts Nothing and Explains Everything,” The Federalist, June 8, 2015]

Howard Hyde also weighs in with “Climate Change: Where Is the Science?” (American Thinker, June 11, 2015).

Bill Nye, the so-called Science Guy, seems to epitomize the influence of ideology on “scientific knowledge.”  I defer to John Derbyshire:

Bill Nye the Science Guy gave a commencement speech at Rutgers on Sunday. Reading the speech left me thinking that if this is America’s designated Science Guy, I can be the nation’s designated swimsuit model….

What did the Science Guy have to say to the Rutgers graduates? Well, he warned them of the horrors of climate change, which he linked to global inequality.

We’re going to find a means to enable poor people to advance in their societies in countries around the world. Otherwise, the imbalance of wealth will lead to conflict and inefficiency in energy production, which will lead to more carbon pollution and a no-way-out overheated globe.

Uh, given that advanced countries use far more energy per capita than backward ones—the U.S.A. figure is thirty-four times Bangladesh’s—wouldn’t a better strategy be to keep poor countries poor? We could, for example, encourage all their smartest and most entrepreneurial people to emigrate to the First World … Oh, wait: we already do that.

The whole climate change business is now a zone of hysteria, generating far more noise—mostly of a shrieking kind—than its importance justifies. Opinions about climate change are, as Greg Cochran said, “a mark of tribal membership.” It is also the case, as Greg also said, that “the world is never going to do much about in any event, regardless of the facts.”…

When Ma Nature means business, stuff happens on a stupendously colossal scale.  And Bill Nye the Science Guy wants Rutgers graduates to worry about a 0.4ºC warming over thirty years? Feugh.

The Science Guy then passed on from the dubiously alarmist to the batshit barmy.

There really is no such thing as race. We are one species … We all come from Africa.

Where does one start with that? Perhaps by asserting that: “There is no such thing as states. We are one country.”

The climatological equivalent of saying there is no such thing as race would be saying that there is no such thing as weather. Of course there is such a thing as race. We can perceive race with at least three of our five senses, and read it off from the genome. We tick boxes for it on government forms: I ticked such a box for the ATF just this morning when buying a gun.

This is the Science Guy? The foundational text of modern biology bears the title On the Origin of Species by Means of Natural Selection, or the Preservation of Favored Races in the Struggle for Life. Is biology not a science?

Darwin said that populations of a species long separated from each other will diverge in their biological characteristics, forming races. If the separation goes on long enough, any surviving races will diverge all the way to separate species. Was Ol’ Chuck wrong about that, Mr. Science Guy?

“We are one species”? Rottweilers and toy poodles are races within one species, a species much newer than ours; yet they differ mightily, not only in appearance but also—gasp!—in behavior, intelligence, and personality. [“Nye Lied, I Sighed,” Taki’s Magazine, May 21, 2015]

AGW in Austin?

“Climate change” is religion refracted through the lens of paganism.

Melanie Phillips

There is a hypothesis that the purported rise in global temperatures since 1850 (or some shorter span if you’re embarrassed by periods of notable decline after 1850) was or is due mainly or solely to human activity, as manifested in emissions of CO2. Adherents of this hypothesis call the supposed phenomenon by various names: anthropogenic global warming (AGW), just plain global warming, climate change, and climate catastrophe, for example.

Those adherents loudly advocate measures that (they assert) would reduce CO2 emissions by enough to avoid climatic catastrophe. They have been advocating such measures for about 25 years, yet climate catastrophe remains elusive. (See “pause,” below.) But the true believers in AGW remain steadfast in their faith.

Actually, belief in catastrophic AGW requires three leaps of faith. The first leap is to assume the truth of the alternative hypothesis — a strong and persistent connection between CO2 emissions and global temperatures — without having found (or even looked for) scientific evidence which disproves the null hypothesis, namely, that there isn’t a strong and persistent connection between CO2 emissions and global temperatures. The search for such evidence shouldn’t be confined to the near-past, but should extend centuries, millennia, and eons into the past. The problem for advocates of AGW is that a diligent search of that kind works against the alternative hypothesis and supports the null hypothesis. As a result, the advocates of AGW confine their analysis to the recent past and substitute kludgy computer models, full of fudge-factors, for a disinterested examination of the actual causes of climate change. There is strong evidence that such causes include solar activity and its influence on cloud formation through cosmic radiation. That truth is too inconvenient for the AGW mob, as are many other truths about climate.

The second leap of faith is to assume that rising temperatures, whatever the cause, are a bad thing. This, despite the known advantages of warmer climates: longer growing seasons and lower death rates, to name but two. This is so because believers in AGW and policies that would (according to them) mitigate it, like to depict worst-case scenarios about the extent of global warming and its negative effects.

The third leap of faith is related to the first two. It is the belief that policies meant to mitigate global warming — policies that mainly involve the curtailment of CO2 emissions — would be (a) effective and (b) worth the cost. There is more than ample doubt about both propositions, which seem to flow from the kind of anti-scientific mind that eagerly embraces the alternative hypothesis without first having disproved the null hypothesis. It is notable that “worth the cost” is a value judgment which springs readily from the tongues and keyboards of affluent Westerners like __________ who already have it made. (Insert “Al Gore”, “high-end Democrats,” “liberal pundits and politicians,” etc.)

Prominent among the leapers-of-faith in my neck of the woods is the “chief weathercaster” of an Austin TV station. We watch his weather forecasts because he spews out more information than his competitors, but I must resist the urge to throw a brick through my TV screen when his mask slips and he reveals himself as a true believer in AGW. What else should I expect from a weather nazi who proclaims it “nice” when daytime high temperatures are in the 60s and 70s, and who bemoans higher temperatures?

Like any nazi, he projects his preferences onto others — in this case his viewership. This undoubtedly includes a goodly number of persons (like me) who moved to Austin and stay in Austin for the sake of sunny days when the thermometer is in the 80-to-95-degree range. It is a bit much when temperatures are consistently in the high 90s and low 100s, as they are for much of Austin’s summer. But that’s the price of those sunny days in the 80s and low 90s, unless you can afford to live in San Diego or Hawaii instead of Austin.

Anyway, the weather nazi would make a great deal out of the following graph:

12-month average temperatures in Austin_1977-2015

The graph covers the period from April 1977 through April 2015. The jagged line represents 12-month averages of monthly averages for the official National Weather Service stations in Austin: Mueller Airport (until July 1999) and Camp Mabry (July 1999 to the present). (There’s a history of Austin’s weather stations in a NOAA document, “Austin Climate Summary.”) The upward trend is unmistakeable. Equally unmistakeable is the difference between the early and late years of the period — a difference that’s highlighted by the y-error bars, which represent a span of plus-and-minus one standard deviation from the mean for the period.

Your first question should be “Why begin with April 1977?” Well, it’s a “good” starting point — if you want to sell AGW — because the 12-month average temperature as of April 1977 was the lowest in 64 years. After all, it was the seemingly steep increase in temperatures after 1970 that sparked the AGW business.

What about the “fact” that temperatures have been rising since about 1850? The “fact” is that temperatures have been recorded in a relatively small number of locales continuously since the 1850s, though the reliability of the temperature data and their relationship to any kind of “global” average is in serious doubt. The most reliable data come from weather satellites, and those have been in operation only since the late 1970s.

A recent post by Bob Tisdale, “New UAH Lower Troposphere Temperature Data Show No Global Warming for More Than 18 Years” (Watts Up With That?, April 29, 2015), summarizes the history of satellite readings, in the course of documenting the “pause” in global warming. The “pause,” if dated from 2001, has lasted 14 years; if dated from 1997, it has lasted 18 years. In either event, the “pause” has lasted about as long as the rise in late-20th century temperatures that led to the AGW hypothesis.

What about those observations since the 1850s? Riddled with holes, that’s what. And even if they were reliable and covered a good part of the globe (which they aren’t and don’t), they wouldn’t tell the story that AGW enthusiasts are trying to sell. Take Austin, for example, which has a (broken) temperature record dating back to 1856:

12-month average temperatures in Austin_1856-2015

Looks just like the first graph? No, it doesn’t. The trend line and error bars suggest a trend that isn’t there. Strip away the trend line and the error bars, and you see this:

12-month average temperatures in Austin_1856-2015_2

Which is what? There’s a rise in temperatures between the 1850s and the early 1890s, consistent with the gradual warming that followed the Little Ice Age. The gap between the early 1890s and mid-19naughts seems to have been marked by lower temperatures. It’s possible to find several mini-trends between the mid-19naughts and 1977, but the most obvious “trend” is a flat line for the entire period:

12-month average temperatures in Austin_1903-1977

Following the sudden jump between 1977 and 1980, the “trend” remains almost flat through 1997, albeit at a slightly higher level:

12-month average temperatures in Austin_1980-1997

The sharpest upward trend really began after the very strong (and naturally warming) El Niño of 1997-1998:

12-month average temperatures in Austin_1997-2015

Oh, wait! It turns out that Austin’s sort-of hot-spell from 1998 to the present coincides with the “pause” in global warming:

The pause_from WUWT_20150429
Source: Bob Tisdale, “New UAH Lower Troposphere Temperature Data Show No Global Warming for More Than 18 Years,” Watts Up With That?, April 29, 2015.

What a revolting development this would be for our local weather nazi, if he could be bothered to acknowledge it. And if he did, he’d have to look beyond the egregious AGW hypothesis for an explanation of the warmer temperatures that he abhors. Where should he look? Here: the rapid increase in Austin’s population, combined with a drought.

The rapid increase in Austin’s population since 2000 probably has caused an acceleration of the urban heat-island (UHI) effect. This is known to inflate city temperatures above those in the surrounding countryside by several degrees.

What about drought? In Austin, the drought of recent years is far less severe than the drought of the 1950s, but temperatures have risen more in recent years than they did in the 1950s:

Indices of 5-year average precipitation and temperature

Why? Because Austin’s population is now six times greater than it was in the 1950s. The UHI effect has magnified the drought effect.

Conclusion: Austin’s recent hot weather has nothing to do with AGW. But don’t try to tell that to a weather nazi — or to the officials of the City of Austin, who lurch zombie-like onward in their pursuit of “solutions” to a non-problem.

BE SURE TO READ THE SEQUEL, IN WHICH I QUANTIFY THE EFFECTS OF PRECIPITATION AND POPULATION, LEAVING NOTHING ON THE TABLE FOR AGW.

Paul Mirengoff explores the similarities between Neville Chamberlain and Barack Obama; for example:

We see with Chamberlain the same curious dynamic present in the Obama presidency. At home, a tough-as-nails administration/political machine that takes no prisoners and rarely compromises; abroad, a feckless operation with a pattern of caving to belligerent adversaries. [Neville Chamberlain and Barack Obama: The Similarities Run Deep,” Powerline Blog, April 15, 2014]

See also John Hinderaker’s Powerline post, “Daniel Pipes: The Obama Doctrine Serves Up One Disaster After Another” (April 6, 2015), and a piece by Eileen F. Toplansky,”Obama’s Three Premises” (American Thinker, April 20, 2015).

What is Obama up to? For my take, see “Does Obama Love America?

If it were possible to convince a climate alarmist that he is wrong, Christopher Monckton of Brenchley is the man for the job:

What Evidence,” asks Ronald Bailey’s headline (www.reason.com, April 3, 2015), “Would Convince You That Man-Made Climate Change Is Real?

The answer: a rational, scientific case rooted in established theory and data would convince me that manmade climate change is a problem. That it is real is not in doubt, for every creature that breathes out emits CO2 and thus affects the climate.

The true scientific question, then, is not the fatuous question whether “Man-Made Climate Change Is Real” but how much global warming our sins of emission may cause, and whether that warming might be more a bad thing than a good thing.

However, Mr Bailey advances no rational case. What, then, are the elements of a rational, scientific case that our influence on the climate will prove dangerous unless the West completes its current self-shutdown?… [How to Convince a Climate Skeptic He’s Wrong,” Watts Up With That, April 9, 2015]

There follows a step-by-step dismantling of Mr. Bailey’s case for alarmism. Lord Monckton ends with this:

[I]f Mr Bailey does me the courtesy of reading the above, he will realize that temperatures are not rising by much, glacial ice-melt (if occurring) is on too small a scale to raise sea level by much, global sea ice extent shows little change in two generations, ditto northern-hemisphere snow cover, there has been little increase in rainfall and (according to the IPCC) little evidence for “stronger rainstorms”, and the ocean warming is so small that it falls within the considerable measurement error.

The evidence he adduces is questionable at best on every count. The Temple of Thermageddon will have to do better than that if it wants to convince us in the teeth of the evidence….

…[N]o rational scientific or economic case can be made for taking any action whatsoever today in a probably futile and certainly cost-ineffective attempt to make global warming that is not happening as predicted today go away the day after tomorrow.

The correct policy to address what is likely to prove a non-problem – and what, even if it were every bit as much of a problem as the tax-gobblers would wish, could not by even their most creative quantitative easing be cost-effectively solved by any attempt at mitigation – is to have the courage to do nothing now and adapt later if necessary.

The question is why, in the teeth of the scientific and economic evidence, nearly all of the global governing class were so easily taken in or bought out or both by the strange coalescence of powerful vested interests who have, until now, profited so monstrously by the biggest fraud in history at such crippling expense in lives and treasure to the rest of us, and at such mortal threat to the integrity and trustworthiness of science itself. [Ibid.]

My own modest effort to quell climate alarmism is summarized in “AGW: The Death Knell.”

Steve Sailer has some fun with the latest bit of experimental hocus-pocus by the intelligence-isn’t-heritable crowd, as interpreted by a reporter for The Washington Post:

In the last few years, there appears to have been a decision to blame racial differences in intelligence on differences in income level, although, of course, that’s not very plausible. That’s what people said way back in 1965, but then the federal Coleman Report of 1966 showed that affluent black students weren’t setting the world on fire academically on average, and vast amounts of data have accumulated validating the Coleman Report ever since.

But a half century later we’re back to asserting the same untested theories as in 1965….

Allow me to point out that a national newspaper has asked a couple of guys who know what they are talking about to punch holes in the latest bit of goodthink and, as of press time, the American public hasn’t dug up Hitler’s DNA and elected it President. So maybe we’re actually mature enough to discuss reality rather than lie all the time?…

Six decades from now, the Education Secretary of the hereditary Bush-Clinton Administration will be declaring the key periods for federal intervention are the eight months and 29 days before birth … but not a day sooner! [Charles Murray and James Thompson Asked Their Opinions in ‘Post’ Article on Brain Size; World Hasn’t Ended, Yet,” The Unz Review, April 15, 2015]

Along the way, Sailer links to Dr. James Thompson’s post about the article in question. There’s a followup post by Thompson, and this one is good, too. See also this post by Sailer.

Gregory Cochran has a related post (“Scanners Live in Vain,” West Hunter, March 31, 2015), where he says this about the paper and the reporting about it:

There is a new paper out in Nature Neuroscience,  mainly by Kimberly Noble, on socioeconomic variables and and brain structure:  Family income, parental education and brain structure in children and adolescents. They found that cortex area went up with income, although more slowly at high incomes.  Judging from their comments to the press, the authors think that being poor shrinks your brain.

Of course, since intelligence is highly heritable, and since people in higher social classes, or with high income, have higher average IQs (although not nearly as high as I would like), you would expect their kids to be, on average, smarter than kids from low-income groups (and have larger brains, since brain size is correlated with IQ) for genetic reasons.  But I guess the authors of this paper have never heard of  any of that – which raises the question, did they scan the brains of the authors?  Because that would have been interesting.  You can actually do microscopic MRI.

Even better, in talking to Nature, another researcher, Martha Farah,  mentions unpublished work that shows that the brain-size correlation with SES  is already there (in African-American kids) by age one month!

Of course, finding that the pattern already exists at the age of one month seriously weakens any idea that being poor shrinks the brain: most of the environmental effects you would consider haven’t even come into play in the first four weeks, when babies drink milk, sleep, and poop. Genetics affecting both parents and their children would make more sense, if the pattern shows up so early (and I’ll bet money that, if real,  it shows up well before one month);  but Martha Farah, and the reporter from Nature, Sara Reardon, ARE TOO FUCKING DUMB to realize this.

And John Ray points to this:

Quick thinkers are born not made, claim scientists.

They have discovered a link between our genes and the ability to remain mentally on the ball in later life.

It is the first time a genetic link has been shown to explain why some people have quick thinking skills.

Researchers identified a common genetic variant – changes in a person’s genetic code – related to how quickly a person is able to process new information. [Jenny Hope, “Quick Thinkers Are Born Not Made: The Speed at Which We Process New Information Is Written in Our Genes,” DailyMail.com, April 16, 2015]

Dr. Ray links to the underlying studies, here.

I’ve probably said more than I should say about the heritability of intelligence in “Race and Reason: The Achievement Gap — Causes and Implications,” “Evolution and Race,” “‘Wading’ into Race, Culture, and IQ,” and “The Harmful Myth of Inherent Equality.”

*     *     *

Speaking of equality, or the lack thereof, Daniel Bier explains “How Piketty Manufactured Rising [Wealth] Inequality in 6 Steps” (Foundation for Economic Education, April 9, 2015):

Piketty’s chart on US wealth inequality displayed a trend that none of its original sources showed. Worst of all, he didn’t tell his readers that he had done any of this, much less explained his reasoning.

But now Magness has deconstructed the chart and shown, step by step, how Piketty tortured his sources into giving him the result he wanted to see….

If your methods can produce opposite results using the same sources, depending entirely on your subjective judgment, you’re not doing science — you’re doing a Choose Your Own Adventure story where you start from the conclusion and work backwards.

Now that you’ve seen how it’s done, you too can “piketty” your data and massage your narrative into selling 1.5 million books — that almost no one will actually read, but will be widely cited as justification for higher taxes nonetheless.

Committed leftists will ignore Piketty’s step back from extreme redistributionism, which I discussed in “Not-So-Random Thoughts (XIII).”

*     *     *

Committed leftists will lament the predicate of “Has Obamacare Turned Voters Against Sharing the Wealth?” (The New York Times, April 15, 2015). The author of the piece, Thomas B. Edsall (formerly of The Washington Post), clearly laments the possibility. (I do not, of course.) Edsall’s article is full of good news (for me); for example:

In 2006, by a margin of more than two to one, 69-28, those surveyed by Gallup said that the federal government should guarantee health care coverage for all citizens of the United States. By late 2014, however, Gallup found that this percentage had fallen 24 points to 45 percent, while the percentage of respondents who said health care is not a federal responsibility nearly doubled to 52 percent.

Edsall’s main worry seems to be how such a mood shift will help Republicans. Evidently, he doesn’t care about taxpayers, people who earn their income, or economic growth, which is inhibited by redistribution from “rich” to “poor.” But what else is new? Edsall is just another representative of the elite punditariat — a member of the “top” part of the left’s “top and bottom” coalition.

Edsall and his ilk should be worried. See, for example, “The Obamacare Effect: Greater Distrust of Government” (the title tells the tale) and “‘Blue Wall’ Hype” which debunks the idea that Democrats have a lock on the presidency.

*     *     *

The question of nature vs. nurture, which I touched on three entries earlier, is closely related to the question of innate ability vs. effort as the key to success in a field of endeavor. “Scott Alexander” of Slate Star Codex has written at length about innate ability vs. effort in two recent posts: “No Clarity Around Growth Mindset…Yet” and “I Will Never Have the Ability to Clearly Explain My Beliefs about Growth Mindset.” (That should be “to explain clearly.”)

This is from the first-linked post:

If you’re not familiar with it, growth mindset is the belief that people who believe ability doesn’t matter and only effort determines success are more resilient, skillful, hard-working, perseverant in the face of failure, and better-in-a-bunch-of-other-ways than people who emphasize the importance of ability. Therefore, we can make everyone better off by telling them ability doesn’t matter and only hard work does.

This is all twaddle, as “Alexander” shows, more or less, in his two very long posts. My essay on the subject is a lot shorter and easier to grasp: “The Harmful Myth of Inherent Equality.”

*     *     *

ENTRIES ADDED 04/19/15:

Obamacare, not unsurprisingly to me, has led to the rationing of health care, according to Bob Unruh’s “Obamacare Blocks Patients Paying for Treatment” (WND, March 6, 2014). And Aleyne Singer delivers “More Proof Obamacare Is Increasing Coverage but Not Access to Health Care” (The Daily Signal, December 9, 2014).

None of this should surprise anyone who thought about the economics of Obamacare, as I did in “Rationing and Health Care,” “The Perils of Nannyism: The Case of Obamacare,” “More about the Perils of Obamacare,” and “Health-Care Reform: The Short of It.”

Ben Bernanke asks “Why Are Interest Rates So Low?” (Ben Bernanke’s Blog, March 30, 2015). His answer? In so many words, business is bad, which means that the demand for capital financing is relatively weak. But in a followup post, “Why Are Interest Rates So Low, Part 2: Secular Stagnation” (Ben Bernanke’s Blog, March 31, 2015), Bernanke argues that the problem isn’t secular stagnation.

I agree that interest rates are low because the economy remains weak, despite some recovery from the nadir of the Great Recession. But, unlike Bernanke, I don’t expect the economy to make a full recovery — and I’m talking about real growth, not phony unemployment-rate recovery. Why Not? See “Obamanomics in Action” and “The Rahn Curve Revisited.” The economy will never grow to its potential as long as the dead hand of government continues to press down on it.

Rationalism, Empiricism, and Scientific Knowledge

Take a very large number, say, 1 quintillion. Written out, it looks like this: 1,000,000,000,000,000,000. It can also be expressed as 1018 or 10.E+18.

I doubt that any human being has ever discerned 1 quintillion discrete objects in a single moment. Including the constituents of all of the stars and planets, there may be more than 1 quintillion particles of matter in the visible portion of the sky on a clear night. But no person may reasonably claim to have seen all of those particles of matter as individual objects.

I doubt, further, that any human being has ever discerned 1 million  objects in a lifetime, even a very long lifetime. And if I’m wrong about that, it’s certainly possible to conjure a number high enough to be well beyond the experiential capacity of any human being; 101000, for instance.

Despite the impossibility of experiencing 101000 things, it is possible to write the number and to perform mathematical operations which involve the number. So, in some sense, very large numbers “exist.” But they exist only because human beings are capable of thinking of them. They are not “real” in the same way that a sky full of stars and planets is real.

Numbers and mathematics are rational constructs of the minds of human beings. Stars and planets are observed; that is, there is empirical evidence of their existence.

Thus there are two1 types of scientific knowledge: rational2 and empirical. They are related in the following ways:

1. Rational knowledge builds on empirical knowledge. Astronomical observations enabled Copernicus to devise a mathematical heliocentric model of the universe, which was an improvement on the geocentric model.

2. Empirical knowledge builds on rational knowledge. Observations aimed at verifying the heliocentric model led eventually to the discovery that the Sun is not at the center of the universe.

3. Empirical knowledge may affirm or contradict rational knowledge. Einstein’s general theory of relativity, which is given in a paper written in 1915, says that light is deflected (bent) by gravity. Astronomical observations made in 1919 affirmed the effect of gravity on light. Had the observations contradicted the postulated effect, the general theory (if any) might be markedly different than the one set forth in 1915. (A scientific theory is more than a hypothesis; it has been substantiated, though it always remains open to refutation.)

4. Rational knowledge may lead to empirical knowledge. One of the postulates that underlies Einstein’s special theory of relativity is the constancy of the speed of light; that is, the speed of light is independent of the motion of the source or the observer. This is unlike (for example) the speed of a ball that is thrown inside a moving train car, in the direction of the train car’s motion. An observer who is stationary relative to the train car will see the speed of the ball as the sum of (a) its speed relative to the thrower and (b) the speed of the train car relative to the observer. Einstein’s postulate, which drew on James Clerk Maxwell’s empirically based theory of electromagnetism, was subsequently verified experimentally.

These reflections lead me to four conclusions:

  • Knowledge is provisional. Human beings often don’t know what to make of the things that they perceive, and what they make of those things is often found to be wrong.
  • When it comes to science, rational and empirical knowledge are intertwined, and their effects are cumulative.
  • Rational knowledge that can’t be or hasn’t been put to an empirical test is merely a hypothesis. The hypothesis may be correct, but it doesn’t represent knowledge.
  • Empirical knowledge necessarily precedes rational knowledge because hypotheses draw on empirical knowledge and must be substantiated by empirical knowledge.3

1. This post focuses on scientific knowledge and ignores other phenomena that are sometimes classified as branches of knowledge, such as emotional knowledge.

2. In this context, rational means by virtue of reason, not lucid or sane. The discussion of rational knowledge is restricted to knowledge that derives from and is a logical extension of observed phenomena, as in the example with which the post begins. I will not, in this post, deal with intuition, innate knowledge, or innate concepts, which are also treated under the heading of rational knowledge.

3. Unless it is true that human beings are born with certain kinds of knowledge, or with certain concepts that can be filled in by knowledge. The article by Markie treats these possibilities at some length.

Jeremy Egerer says this “In Defense of a Beautiful Boss” (American Thinker, February 8, 2015):

Leftists have been waging a war against nearly every personal advantage for years: if they aren’t upset because your parents are rich, they’ll insult you because your parents are white, or maybe because you have a penis.  In their most unreasonable moments, they might even be upset that you deserve your own job.  It seems only reasonable to expect that sooner or later, they would be complaining about whether or not our bosses keep themselves in shape.

This is because at the heart of all leftism lies an unreasonable envy of all advantage (disguised as an advocacy of the disadvantaged) and an unhealthy hatred of actual diversity (disguised as an appreciation of difference).  They call life a meritocracy when your successful parents raise you to win, which is a lot like complaining that your parents raised you at all.  It’s almost enough to make you wonder whether they loathe the laws of cause and effect.  In the fight against all odds – not his, but everyone’s – the leftist hasn’t only forgotten that different people breed different people; he’s forgotten that different people are diversity itself, and that diversity, the thing he claims to be championing, means that someone is going to have natural advantages.

Spot on. I have addressed the left’s war on “lookism” in “How to Combat Beauty-ism” and “An Economist’s Special Pleading: Affirmative Action for the Ugly.”

John Ray tackles “Conservative and Liberal Brains Again” (A Western Heart, February 14, 2015):

Most such reports [Current Biology 21, 677–680, April 26, 2011 ª2011. DOI 10.1016/j.cub.2011.03.017] are … parsimoniously interpreted as conservatives being more cautious, which is hardly a discovery. And if there is something wrong with caution then there is everything wrong with a lot of things.  Science, for instance, is a sustained exercise in caution. So conservatives are born more cautious and Leftist brains miss most of that out.  So [a commentary that conservatives are] “sensitive to fear” … could be equally well restated as “cautious”.  And the finding that liberals “have a higher capacity to tolerate uncertainty and conflicts” is pure guesswork [on the part of the commentators].  As the report authors note, that is just “one of the functions of the anterior cingulate cortex”.

Despite the apparent even-handedness of the authors of the study cited by Dr. Ray, the field of psychology has long had a pro-left tilt. See, for example, my posts “Conservatism, Libertarianism, and the ‘Authoritarian Personality’,” “The F Scale, Revisited,” and “The Psychologist Who Played God.”

Income inequality is another item in the long list of subjects about which leftists obsess, despite the facts of the matter. Mark J. Perry, as usual, deals in facts: “US Middle Class Has Disappeared into Higher-Income Groups; Recent Stagnation Explained by Changing Household Demographics?” (AEI.org, February 4, 2015) and “Evidence Shows That Affluence in the US Is Much More Fluid and Widespread Than The Rigid Class Structure Narrative Suggests” (AEI.org, February 25, 2015). The only problem with these two posts is Perry’s unnecessary inclusion of a question mark in the title of the first one. For more on the subject, plus long lists of related posts and readings, see my post, “Mass (Economic) Hysteria: Income Inequality and Related Themes.”

*     *     *

Speaking of leftists who obsess about income inequality — and get it wrong — there’s Thomas Piketty, author of the much-rebutted Capital in the Twenty-First Century. I have much to say about Deidre McCloskey’s take-down of Piketty in “McCloskey on Piketty.” David Henderson, whose review of Capital is among the several related readings listed in my post, has more to say; for example:

McCloskey’s review is a masterpiece. She beautifully weaves together economic history, simple price theory, basic moral philosophy, and history of economic thought. Whereas I had mentally put aside an hour to read and think, it took only about 20 minutes. I highly recommend it. (“McCloskey on Piketty,” EconLog, February 25, 2015)

Henderson continues by sampling some of Piketty’s many errors of fact, logic, and economic theory that McCloskey exposes.

*     *     *

Although it won’t matter to committed leftists, Piketty seems to have taken some of this critics to heart. James Pethokoukis writes:

[I]n a new paper, Piketty takes a step or two backward. He now denies that he views his simple economic formula “as the only or even the primary tool for considering changes in income and wealth in the 20th century, or for forecasting the path of income and wealth inequality in the 21st century.” Seems his fundamental law isn’t so fundamental after all once you factor in things like how some of that wealth is (a) spent on super-yachts and bad investments; (b) divided among children through the generations; and (c) already taxed fairly heavily. In particular, the rise in income inequality, as opposed to wealth inequality, has “little to do” with “r > g,” he says….

Piketty’s modest retreat isn’t all that surprising, given the withering academic assault on his research. In a survey of top economists late last year, 81 percent disagreed with his thesis. And several used fairly rough language — at least for scholars — such as “weak” and not “particularly useful,” with one accusing Piketty of “poor theory” and “negligible empirics.”

This is all rather bad news for what I have termed the Unified Economic Theory of Modern Liberalism: Not only are the rich getting richer — and will continue to do so because, you know, capitalism — but this growing gap is hurting economic growth. Redistribution must commence, tout de suite!

But Piketty’s clarification isn’t this politically convenient theory’s only problem. The part about inequality and growth has also suffered a setback. The link between the two is a key part of the “secular stagnation” theory of superstar Democratic economist Lawrence Summers. Since the rich save more than the middle class, growing income inequality is sapping the economy of consumer demand. So government must tax more and spend more. But Summers recently offered an updated view, saying that while boosting consumer demand is necessary, it is not sufficient for strong economic growth. Washington must also do the sort of “supply-side” stuff that Republicans kvetch about, such as business tax reform.

…[C]oncern about the income gap shouldn’t be used an excuse to ignore America’s real top problem, a possible permanent downshift in the growth potential of the U.S. economy. At least Piketty got half his equation right. [“The Politically Convenient but Largely Bogus Unified Economic Theory of Modern Liberalism,” The Week, March 11, 2015]

Harvard’s Robert Putnam is another class warrior, whose propagandistic effusion “E Pluribus Unum: Diversity and Community in the Twenty-first Century“ I skewer in “Society and the State” and “Genetic Kinship and Society.” I was therefore gratified to read in Henry Harpending’s post, “Charles Murray and Robert Putnam on Class” (West Hunter, March 20, 2015) some things said by John Derbyshire about Putnam’s paper:

That paper has a very curious structure. After a brief introduction (two pages), there are three main sections, headed as follows:

The Prospects and Benefits of Immigration and Ethnic Diversity (three pages)
Immigration and Diversity Foster Social Isolation (nineteen pages)
Becoming Comfortable with Diversity (seven pages)

I’ve had some mild amusement here at my desk trying to think up imaginary research papers similarly structured. One for publication in a health journal, perhaps, with three sections titled:

Health benefits of drinking green tea
Green tea causes intestinal cancer
Making the switch to green tea

Social science research in our universities cries out for a modern Jonathan Swift to lampoon its absurdities.

Amen.

*     *     *

Putnam is a big booster of “diversity,” which — in the left’s interpretation — doesn’t mean diversity of political, social, and economic views. What it means is the forced association of persons of irreconcilably opposed social norms. I say some things about that in “Society and the State” and “Genetic Kinship and Society.” Fred Reed has much more to say in a recent column:

In Ferguson blacks are shooting policemen as others cheer. It does a curmudgeon’s soul good: Everything gets worse, the collapse continues, and unreasoning stupidity goes thundering into the future.

We will hear I suppose that it wasn’t racial, that teens did it, that discrimination  caused it, white privilege, racism, institutional racism, slavery, colonialism, bigots, Southerners, rednecks—everything but the hatred of blacks for whites.

And thus we will avoid the unavoidable, that racial relations are a disaster, will remain a disaster, will get worse, are getting worse, and will lead to some awful denouement no matter how much we lie, preen, vituperate, chatter like Barbary apes, or admire ourselves.

It isn’t working. There is no sign that it ever will. What now?

The only solution, if there is a solution, would seem to be an amicable separation. This methinks would be greatly better than the slow-motion, intensifying racial war we now see, and pretend not to see. When the races mix, there is trouble. So, don’t mix them….

The racial hostility of blacks for whites can be seen elsewhere, for example in targeting of crime, most starkly in interracial rates of rape…. The numbers on rape, almost entirely black on white, also check out as cold fact… This has been analyzed to death, and ignored to death, but perhaps the most readable account is Jim Goad’s For Whom the Cat Calls (the numbers of note come below the ads).

Even without the (inevitable) racial hostility, togetherheid would not work well. The races have little or nothing in common. They do not want the same things. Whites come from a literate European tradition dating at least from the Iliad in 800 BC, a tradition characterized by literature, mathematics, architecture, philosophy, and the sciences. Africa, having a very different social traditions, was barely touched by this, and today blacks still show little interest. Even in the degenerate America of today, whites put far more emphasis on education than do blacks.

The media paint the problems of blacks as consequent to discrimination, but they clearly are not. If blacks in white schools wanted to do the work, or could, whites would applaud. If in black schools they demanded thicker textbooks with bigger words and smaller pictures, no white would refuse. The illiteracy, the very high rates of illegitimacy, the crime in general, the constant killing of young black men by young black men in particular—whites do not do these. They are either genetic, and irremediable, or cultural, and remediable, if at all, only in the very long run. We live in the short run.

Would it then not be reasonable to encourage a voluntary segregation? Having only black policemen in black regions would slow the burning of cities. If we let people live among their own, let them study what they chose to study, let them police themselves and order their schools as they chose, considerable calm would fall over the country.

If the races had the choice of running their own lives apart, they would. If this is not true, why do we have to spend such effort trying to force them together?

It is a great fallacy to think that because we ought to love one another, we will; or that because bloodshed among groups makes no sense, it won’t happen. The disparate seldom get along, whether Tamils and Sinhalese or Hindus and Moslems or Protestants and Catholics or Jews and Palestinians. The greater the cultural and genetic difference, the greater the likelihood and intensity of conflict. Blacks and whites are very, very different….

Separation does not imply disadvantage. The assertion that “separate is inherently unequal” is a catchiphrastic embodiment of the Supreme Court’s characteristic blowing in the political wind. A college for girls is not inherently inferior to a college for boys, nor a yeshiva for Jews inherently inferior to a parish school for Catholics. And maybe it is the business of girls and boys, Catholics and Jews, to decide what and where they want to study—not the government’s business….

Anger hangs over the country. Not everyone white is a professor or collegiate sophomore or network anchor. Not every white—not by a long shot—in Congress or the federal bureaucracy is a Mother Jones liberal, not in private conversation. They say aloud what they have to say. But in the Great Plains and small-town South, in corner bars in Chicago and Denver, in the black enclaves of the cities, a lot of people are ready to rumble. Read the comments section of the St. Louis papers after the riots. We can call the commenters whatever names we choose but when we finish, they will still be there. The shooting of policemen for racial reasons–at least four to date–is not a good sign. We will do nothing about it but chatter. [“The Symptoms Worsen,” Fred on Everything, March 15, 2015]

Humbug” (January 13, 2015) and my posts, “Race and Reason: The Achievement Gap — Causes and Implications,” “The Hidden Tragedy of the Assassination of Lincoln.”, “‘Conversing’ about Race,” “‘Wading’ into Race, Culture, and IQ,” “Round Up the Usual Suspects,”and “Evolution, Culture, and ‘Diversity’.”

In “The Fallacy of Human Progress” I address at length the thesis of Steven Pinker’s ludicrous The Better Angels of Our Nature: Why Violence Has Declined. In rebuttal to Pinker, I cite John Gray, author of The Silence of Animals: On Progress and Other Modern Myths:

Gray’s book — published  18 months after Better Angels — could be read as a refutation of Pinker’s book, though Gray doesn’t mention Pinker or his book.

Well, Gray recently published a refutation of Pinker’s book, which I can’t resist quoting at length:

The Better Angels of Our Nature: a history of violence and humanity (2011) has not only been an international bestseller – more than a thousand pages long and containing a formidable array of graphs and statistics, the book has established something akin to a contemporary orthodoxy. It is now not uncommon to find it stated, as though it were a matter of fact, that human beings are becoming less violent and more altruistic. Ranging freely from human pre-history to the present day, Pinker presents his case with voluminous erudition. Part of his argument consists in showing that the past was more violent than we tend to imagine…. This “civilising process” – a term Pinker borrows from the sociologist Norbert Elias – has come about largely as a result of the increasing power of the state, which in the most advanced countries has secured a near-monopoly of force. Other causes of the decline in violence include the invention of printing, the empowerment of women, enhanced powers of reasoning and expanding capacities for empathy in modern populations, and the growing influence of Enlightenment ideals….

Another proponent of the Long Peace is the well-known utilitarian philosopher Peter Singer, who has praised The Better Angels of Our Nature as “a supremely important book … a masterly achievement. Pinker convincingly demonstrates that there has been a dramatic decline in violence, and he is persuasive about the causes of that decline.” In a forthcoming book, The Most Good You Can Do, Singer describes altruism as “an emerging movement” with the potential to fundamentally alter the way humans live….

Among the causes of the outbreak of altruism, Pinker and Singer attach particular importance to the ascendancy of Enlightenment thinking….

…Pinker’s response when confronted with [contrary] evidence is to define the dark side of the Enlightenment out of existence. How could a philosophy of reason and toleration be implicated in mass murder? The cause can only be the sinister influence of counter-Enlightenment ideas….

The picture of declining violence presented by this new orthodoxy is not all it seems to be. As some critics, notably John Arquilla, have pointed out, it’s a mistake to focus too heavily on declining fatalities on the battlefield….

If great powers have avoided direct armed conflict, they have fought one another in many proxy wars. Neocolonial warfare in south-east Asia, the Korean war and the Chinese invasion of Tibet, British counter-insurgency warfare in Malaya and Kenya, the abortive Franco-British invasion of Suez, the Angolan civil war, the Soviet invasions of Hungary, Czechoslovakia and Afghanistan, the Vietnam war, the Iran-Iraq war, the first Gulf war, covert intervention in the Balkans and the Caucasus, the invasion of Iraq, the use of airpower in Libya, military aid to insurgents in Syria, Russian cyber-attacks in the Baltic states and the proxy war between the US and Russia that is being waged in Ukraine – these are only some of the contexts in which great powers have been involved in continuous warfare against each other while avoiding direct military conflict.

While it is true that war has changed, it has not become less destructive. Rather than a contest between well-organised states that can at some point negotiate peace, it is now more often a many-sided conflict in fractured or collapsed states that no one has the power to end….

It may be true that the modern state’s monopoly of force has led, in some contexts, to declining rates of violent death. But it is also true that the power of the modern state has been used for purposes of mass killing, and one should not pass too quickly over victims of state terror…. Pinker goes so far as to suggest that the 20th-century Hemoclysm might have been a gigantic statistical fluke, and cautions that any history of the last century that represents it as having been especially violent may be “apt to exaggerate the narrative coherence of this history” (the italics are Pinker’s). However, there is an equal or greater risk in abandoning a coherent and truthful narrative of the violence of the last century for the sake of a spurious quantitative precision….

While the seeming exactitude of statistics may be compelling, much of the human cost of war is incalculable…. [T]he statistics presented by those who celebrate the arrival of the Long Peace are morally dubious if not meaningless.

The radically contingent nature of the figures is another reason for not taking them too seriously. (For a critique of Pinker’s statistical methods, see Nassim Nicholas Taleb’s essay on the Long Peace.)…

Certainly the figures used by Pinker and others are murky, leaving a vast range of casualties of violence unaccounted for. But the value of these numbers for such thinkers comes from their very opacity. Like the obsidian mirrors made by the Aztecs for purposes of divination, these rows of graphs and numbers contain nebulous images of the future – visions that by their very indistinctness can give comfort to believers in human improvement….

Unable to tolerate the prospect that the cycles of conflict will continue, many are anxious to find continuing improvement in the human lot. Who can fail to sympathise with them? Lacking any deeper faith and incapable of living with doubt, it is only natural that believers in reason should turn to the sorcery of numbers. How else can they find meaning in their lives?

I close this super-sized installment of “Thoughts” by returning to the subject of so-called net neutrality, which I addressed almost nine years ago in “Why ‘Net Neutrality’ Is a Bad Idea.” Now it’s a bad idea that the FCC has imposed on ISPs and their customers — until, one hopes, it’s rejected by the Supreme Court as yet another case of Obamanomic overreach.

As Robert Tracinski notes,

[b]illionaire investor Mark Cuban recently commented, about a push for new regulations on the Internet, that “In my adult life I have never seen a situation that paralleled what I read in Ayn Rand’s books until now with Net Neutrality.” He continued, “If Ayn Rand were an up-and-coming author today, she wouldn’t write about steel or railroads, it would be Net Neutrality.”

She certainly would, but if he thinks this is the first time real life has imitated Ayn Rand’s fiction, he needs to be paying a little more attention. Atlas has been shrugging for a long, long time. [“Net Neutrality: Yes, Mark Cuban, Atlas Is Shrugging,” The Federalist, March 18, 2015]

The rest of the story is outlined by the headings in Tracinski’s article:

The Relationship Between Net Neutrality and Atlas Shrugged

Internet Execs Are Already Uncomfortable with the Net Neutrality They Demanded

The Parallels Extend Into Fracking

Government Shuts Down Any Runaway Success

Atlas Shrugged Is Coming True Before Our Eyes

As I did in my post, Julian Adorney focuses on the economics of net neutrality:

After a number of false starts and under pressure from the White House, the FCC gave in and voted to regulate the Internet as a public utility in order to ban such practices, thus saving the Internet from a variety of boogeymen.

This is a tempting narrative. It has conflict, villains, heroes, and even a happy ending. There’s only one problem: it’s a fairy tale. Such mischief has been legal for decades, and ISPs have almost never behaved this way. Any ISP that created “slow lanes” or blocked content to consumers would be hurting its own bottom line. ISPs make money by seeking to satisfy consumers, not by antagonizing them.

There are two reasons that ISPs have to work to satisfy their customers. First, every company needs repeat business….

For Internet service providers, getting new business is expensive…. Satisfying customers so that they continue subscribing is cheaper, easier, and more profitable than continually replacing them. ISPs’ self-interest pushes them to add value to their customers just to keep them from jumping ship to their competitors.

In fact, this is what we’ve seen. ISPs have invested heavily in new infrastructure, and Internet speeds have increased by leaps and bounds…. These faster speeds have not been limited to big corporate customers: ISPs have routinely improved their services to regular consumers. They didn’t do so because the FCC forced them. For the past twenty years, “slow lanes” have been perfectly legal and almost as perfectly imaginary….

…ISPs shy away from creating slow lanes not because they have to but because they have a vested interest in offering fast service to all customers.

Contrary to the myth about ISPs being localized monopolies, 80 percent of Americans live in markets with access to multiple high-speed ISPs. While expensive regulations can discourage new players from entering the market, competition in most cities is increasingly robust….

ISPs still have to compete with each other for customers. If one ISP sticks them in the slow lane or blocks access to certain sites — or even just refuses to upgrade its service — consumers can simply switch to a competitor.

The second reason that ISPs seek to satisfy customers is that every business wants positive word of mouth. Consumers who receive excellent service talk up the service to their friends, generating new sign-ups. Consumers who receive mediocre service not only leave but badmouth the company to everyone they know.

In fact, this happened in one of the few cases where an ISP chose to discriminate against content. When Verizon blocked text messages from a pro-choice activist group in 2007, claiming the right to block “controversial or unsavory” messages, the backlash was fierce. Consumer Affairs notes that, “after a flurry of criticism, Verizon reversed its policy” on the pro-choice texts. The decision may have been ideological, but more likely Verizon reversed a policy that was driving away consumers, generating bad press, and hurting its bottom line.

In 2010, an FCC order made such “unreasonable discrimination” illegal (until the rule was struck down in 2014), but even without this rule, consumers proved more than capable of standing up to big corporations and handling such discrimination themselves.

In competitive markets, the consumer’s demand for quality prevents companies from cutting corners. Before the FCC imposed public utility regulations on the Internet, ISPs were improving service and abandoning discriminatory practices in order to satisfy their users. Net Neutrality advocates have spent years demanding a government solution to a problem that  markets had already solved. [“Net Nonsense,” The Freeman, March 18, 2015]

Amen, again.
