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).

Dr. James Thompson, and English psychologist, often blogs about intelligence. Here are some links from last year that I’ve been hoarding:

Intelligence: All That Matters” (a review of a book by Stuart Ritchie)

GCSE Genes” (commentary about research showing the strong relationship between genes and academic achievement)

GWAS Hits and Country IQ” (commentary about preliminary research into the alleles related to intelligence)

Also, from the International Journal of Epidemiology, comes “The Association between Intelligence and Lifespan Is Mostly Genetic.”

All of this is by way of reminding you of my many posts about intelligence, which are sprinkled throughout this list and this one.

Immigration and Intelligence

REVISED 11/18/16

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 was on the verge of changing my mind — something of which I am capable. But I’m not ready to do that. My main reservation now has to do with the effect of mass immigration on crime, which argues strongly against immigration from south of the border.

Intelligence, Personality, Politics, and Happiness (re-post)

I am re-posting this, by popular demand. It’s identical to the updated original.

This post is a collection and refinement of related posts at my earlier blog, Liberty Corner (with updated links). Each section of this post carries the same title as the original post at Liberty Corner. “IQ and Personality” is and has been, by far, the most popular of my Liberty Corner posts, so I give the eponymous section the place of honor in this post.

Web pages that link to this post usually consist of a discussion thread whose participants’ views of the post vary from “I told you so” to “that doesn’t square with me/my experience” or “MBTI is all wet because…”.  Those who take the former position tend to be persons of above-average intelligence whose MBTI types correlate well with high intelligence. Those who take the latter two positions tend to be persons who are defensive about their personality types, which do not correlate well with high intelligence. Such persons should take a deep breath and remember that high intelligence (of the abstract-reasoning-book-learning kind measured by IQ tests) is widely distributed throughout the population. As I say below, ” I am not claiming that a small subset of MBTI types accounts for all high-IQ persons, nor am I claiming that a small subset of MBTI types is populated entirely by high-IQ persons.” All I am saying is that the bits of evidence which I have compiled suggest that high intelligence is more likely — but far from exclusively — to be found among persons with certain MBTI types.

The correlations between intelligence, political leanings, and happiness are admittedly more tenuous. But they are plausible.

Leftists who proclaim themselves to be more intelligent than persons of the right do so, in my observation, as a way of reassuring themselves of the superiority of their views. They have no legitimate basis for claiming that the ranks of highly intelligent persons are dominated by the left. Leftist “intellectuals” in academia, journalism, the “arts,” and other traditional haunts of leftism are prominent because they are vocal. But they comprise a small minority of the population and should not be mistaken for typical leftists, who seem mainly to populate the ranks of the civil service, labor unions, the teaching “profession,” and the unemployed. (It is worth noting that public-school teachers, on the whole, are notoriously dumber than most other college graduates.)

Again, I am talking about general relationships, to which there are many exceptions. If you happen to be an exception, don’t take this post personally. You’re probably an exceptional person.

IQ AND PERSONALITY

Some years ago I came across some statistics about the personality traits of high-IQ persons (those who are in the top 2 percent of the population).* The statistics pertain to a widely used personality test called the Myers-Briggs Type Indicator (MBTI), which I have taken twice. In the MBTI there are four pairs of complementary personality traits, called preferences: Extraverted/Introverted, Sensing/iNtuitive, Thinking/Feeling, and Judging/Perceiving. Thus, there are 16 possible personality types in the MBTI: ESTJ, ENTJ, ESFJ, ESFP, and so on. (For an introduction to MBTI, summaries of types, criticisms of MBTI, and links to other sources, see this article at Wikipedia. A straightforward description of the theory of MBTI and the personality traits can be found here. Detailed descriptions of the 16 types are given here.)

In summary, here is what the statistics indicate about the correlation between personality traits and IQ:

  • Other personality traits being the same, an iNtuitive person (one who grasps patterns and seeks possibilities) is 25 times more likely to have a high IQ than a Sensing person (one who focuses on sensory details and the here-and-now).
  • Again, other traits being the same, an Introverted person is 2.6 times more likely to have a high IQ than one who is Extraverted; a Thinking (logic-oriented) person is 4.5 times more likely to have a high IQ than a Feeling (people-oriented) person; and a Judging person (one who seeks closure) is 1.6 times as likely to have a high IQ than a Perceiving person (one who likes to keep his options open).
  • Moreover, if you encounter an INTJ, there is a 22% probability that his IQ places him in the top 2 percent of the population. (Disclosure: I am an INTJ.) Next are INTP, at 14%; ENTJ, 8%; ENTP, 5%; and INFJ, 5%. (The next highest type is the INFP at 3%.) The  five types (INTJ, INTP, ENTJ, ENTP, and INFJ) account for 78% of the high-IQ population but only 15% of the total population.**
  • Four of the five most-intelligent types are NTs, as one would expect, given the probabilities cited above. Those same probabilities lead to the dominance of INTJs and INTPs, which account for 49% of the Mensa membership but only 5% of the general population.**
  • Persons with the S preference bring up the rear, when it comes to taking IQ tests.**

A person who encountered this post when it was at Liberty Corner claims that “one would expect to see the whole spectrum of intelligences within each personality type.” Well, one does see just that, but high intelligence is skewed toward the five types listed above. I am not claiming that a small subset of MBTI types accounts for all high-IQ persons, nor am I claiming that a small subset of MBTI types is populated entirely by high-IQ persons.

I acknowledge reservations about MBTI, such as those discussed in the Wikipedia article. An inherent shortcoming of psychological tests (as opposed to intelligence tests) is that they rely on subjective responses (e.g., my favorite color might be black today and blue tomorrow). But I do not accept this criticism:

[S]ome researchers expected that scores would show a bimodal distribution with peaks near the ends of the scales, but found that scores on the individual subscales were actually distributed in a centrally peaked manner similar to a normal distribution. A cut-off exists at the center of the subscale such that a score on one side is classified as one type, and a score on the other side as the opposite type. This fails to support the concept of type: the norm is for people to lie near the middle of the subscale.[6][7][8][33][42]

Why was “it was expected” that scores on a subscale (E/I, S/N, T/F, J/P) would show a bimodal distribution? How often does one encounter a person who is at the extreme end of any subscale? Not often, I wager, except in places where such extremes are likely to be clustered (e.g., Extraverts in acting classes, Introverts in monasteries). The cut-off at the center of each subscale is arbitrary; it simply affords a shorthand characterization of a person’s dominant traits. But anyone who takes an MBTI (or equivalent instrument) is given his scores on each of the subscales, so that he knows the strength (or weakness) of his tendencies.

Regarding other points of criticism: It is possible, of course, that a person who is familiar with MBTI tends to see in others the characteristics of their known MBTI types (i.e., confirmation bias). But has that tendency been confirmed by rigorous testing? Such testing would examine the contrary case, that is, the ability of a person to predict the type of a person whom he knows well (e.g., a co-worker or relative). The supposed vagueness of the descriptions of the 16 types arises from the complexity of human personality; but there are differences among the descriptions, just as there are differences among individuals. According to a footnote to an earlier version of the Wikipedia article about MBTI, half of the persons who take the MBTI are able to guess their types before taking it. Does that invalidate MBTI or does it point to a more likely phenomenon, namely, that introspection is a personality-related trait, one that is more common among Introverts than Extraverts? A good MBTI instrument cuts through self-deception and self-flattery by asking the same set of questions in many different ways, and in ways that do not make any particular answer seem like the “right” one.

My considerable exposure to high-IQ scientists in 30 years of working with them is suggestive. Most of them seemed to exhibit the traits of INTJs and INTPs. And those who took an MBTI test were found to be INTJs and INTPs.

IQ AND POLITICS

It is hard to find clear, concise analyses of the relationship between IQ and political leanings. I offer the following in evidence that very high-IQ individuals lean strongly toward libertarian positions.

The Triple Nine Society (TNS) limits its membership to persons with IQs in the top 0.1% of the population. In an undated survey (probably conducted in 2000, given the questions about the perceived intelligence of certain presidential candidates), members of TNS gave their views on several topics (in addition to speculating about the candidates’ intelligence): subsidies, taxation, civil regulation, business regulation, health care, regulation of genetic engineering, data privacy, death penalty, and use of military force.

The results speak for themselves. Those members of TNS who took the survey clearly have strong (if not unanimous) libertarian leanings.

THE RIGHT IS SMARTER THAN THE LEFT

I count libertarians as part of the right because libertarians’ anti-statist views are aligned with the views of the traditional (small-government) conservatives who are usually Republicans. Having said that, the results reported in “IQ and Politics” lead me to suspect that the right is smarter than the left, left-wing propaganda to the contrary notwithstanding. There is additional evidence for my view.

A site called Personality Page offers some data about personality type and political affiliation. The sample is not representative of the population as a whole; the average age of respondents is 25, and introverted personalities are overrepresented (as you might expect for a test that is apparently self-administered through a web site). On the other hand, the results are probably unbiased with respect to intelligence because the data about personality type were not collected as part of a study that attempts to relate political views and intelligence, and there is nothing on the site to indicate a left-wing bias. (Psychologists, who tend toward leftism, have a knack for making conservatives look bad, as discussed here, here, and here. If there is a strong association between political views and intelligence, it is found among so-called intellectuals, where the herd mentality reigns supreme.)

The data provided by Personality Page are based on the responses of 1,222 individuals who took a 60-question personality test that determined their MBTI types (see “IQ and Personality”). The test takers were asked to state their political preferences, given these choices: Democrat, Republican, middle of the road, liberal, conservative, libertarian, not political, and other. Political self-labelling is an exercise in subjectivity. Nevertheless, individuals who call themselves Democrats or liberals (the left) are almost certainly distinct, politically, from individuals who call themselves Republicans, conservatives, or libertarians (the right).

Now, to the money question: Given the distribution of personality types on the left and right, which distribution is more likely to produce members of Mensa? The answer: Those who self-identify as persons of the right are 15% more likely to qualify for membership in Mensa than those who self-identify as persons of the left. This result is plausible because it is consistent with the pronounced anti-government tendencies of the very-high-IQ members of the Triple Nine Society (see “IQ and Politics”).

REPUBLICANS (AND LIBERTARIANS) ARE HAPPIER THAN DEMOCRATS

That statement follows from research by the Pew Research Center (“Are We Happy Yet?” February 13, 2006) and Gallup (“Republicans Report Much Better Health Than Others,” November 30, 2007).

Pew reports:

Some 45% of all Republicans report being very happy, compared with just 30% of Democrats and 29% of independents. This finding has also been around a long time; Republicans have been happier than Democrats every year since the General Social Survey began taking its measurements in 1972….

Of course, there’s a more obvious explanation for the Republicans’ happiness edge. Republicans tend to have more money than Democrats, and — as we’ve already discovered — people who have more money tend to be happier.

But even this explanation only goes so far. If one controls for household income, Republicans still hold a significant edge: that is, poor Republicans are happier than poor Democrats; middle-income Republicans are happier than middle-income Democrats, and rich Republicans are happier than rich Democrats.

Gallup adds this:

Republicans are significantly more likely to report excellent mental health than are independents or Democrats among those making less than $50,000 a year, and among those making at least $50,000 a year. Republicans are also more likely than independents and Democrats to report excellent mental health within all four categories of educational attainment.

There is a lot more in both sources. Read them for yourself.

Why would Republicans be happier than Democrats? Here’s my thought, Republicans tend to be conservative or libertarian (at least with respect to minimizing government’s role in economic affairs). I refer you to a post in which I discussed Thomas Sowell’s A Conflict of Visions:

He posits two opposing visions: the unconstrained vision (I would call it the idealistic vision) and the constrained vision (which I would call the realistic vision). As Sowell explains, at the end of chapter 2:

The dichotomy between constrained and unconstrained visions is based on whether or not inherent limitations of man are among the key elements included in each vision…. These different ways of conceiving man and the world lead not merely to different conclusions but to sharply divergent, often diametrically opposed, conclusions on issues ranging from justice to war.

Idealists (“liberals”) are bound to be less happy than realists (conservatives and libertarians) because idealists’ expectations about human accomplishments (aided by government) are higher than those of realists, and so idealists are doomed to disappointment.

All of this is consistent with findings reported by law professor James Lindgren:

[C]ompared to anti-redistributionists, strong redistributionists have about two to three times higher odds of reporting that in the prior seven days they were angry, mad at someone, outraged, sad, lonely, and had trouble shaking the blues. Similarly, anti-redistributionists had about two to four times higher odds of reporting being happy or at ease. Not only do redistributionists report more anger, but they report that their anger lasts longer. When asked about the last time they were angry, strong redistributionists were more than twice as likely as strong opponents of leveling to admit that they responded to their anger by plotting revenge. Last, both redistributionists and anti-capitalists expressed lower overall happiness, less happy marriages, and lower satisfaction with their financial situations and with their jobs or housework. (From the abstract of Northwestern Law and Economics Research Paper 06-29, “What Drives Views on Government Redistribution and Anti-Capitalism: Envy or a Desire for Social Dominance?,” March 15, 2011.)

THE BOTTOM LINE

If you are very intelligent — with an IQ that puts you in the top 2% of the population — you are most likely to be an INTJ, INTP, ENTJ, ENTP, or INFJ, in that order. Your politics will lean heavily toward libertarianism or small-government conservatism. You probably vote Republican most of the time because, even if you are not a card-carrying Republican, you are a staunch anti-Democrat. And you are a happy person because your expectations are not constantly defeated by reality.

Footnotes:

* I apologize for not having documented the source of the statistics that I cite here. I dimly recall finding them on or via the website of American Mensa, but I am not certain of that. And I can no longer find the source by searching the web. I did transcribe the statistics to a spreadsheet, which I still have. So, the numbers are real, even if their source is now lost to me.

** Estimates of the distribution of  MBTI types  in the U.S. population are given in two tables on page 4 of “Estimated Frequencies of the Types in the United States Population,” published by the Center for Applications of Psychological Type. One table gives estimates of the distribution of the population by preference (E, I, N, S, etc.). The other table give estimates of the distribution of the population among all 16 MBTI types. The statistics for members of Mensa were broken down by preferences, not by types; therefore I had to use the values for preferences to estimate the frequencies of the 16 types among members of Mensa. For consistency, I used the distribution of the preferences among the U.S. population to estimate the frequencies of the 16 types among the population, rather than use the frequencies provided for each type. For example, the fraction of the population that is INTJ comes to 0.029 (2.9%) when the values for I (0.507), N (0.267), T (0.402), and J (0.541) are multiplied. But the detailed table has INTJs as 2.1% of the population. In sum, there are discrepancies between the computed and given values of the 16 types in the population. The most striking discrepancy is for the INFJ type. When estimated from the frequencies of the four preferences, INFJs are 4.4% of the population; the table of values for all 16 types gives the percentage of INFJs as 1.5%.

Using the distribution given for the 16 types leads to somewhat different results:

  • There is a 31% probability that an INTJ’s his IQ places him in the top 2 percent of the population. Next are INFJ, at 14%; ENTJ, 13%; and INTP, 10%. (The next highest type is the ENTP at 4%.) The  four types (INTJ, INFJ, ENTJ, AND INTP) account for 72% of the high-IQ population but only 9% of the total population. The top five types (including ENTPs) account for 78% of the high-IQ population but only 12% of the total population.
  • Four of the five most-intelligent types are NTs, as one would expect, given the probabilities cited earlier. But, in terms of the likelihood of having an IQ, this method moves INFJs into second place, a percentage point ahead of ENTJs.
  • In any event, the same five types dominate, and all five types have a preference for iNtuitive thinking.
  • As before, persons with the S preference generally lag their peers when it comes to IQ tests.

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.

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.

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]

About that bogus inequality-hurts-growth meme, see my post, “Income Inequality and Economic Growth.”

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? [“John Gray: Steven Pinker Is Wrong about Violence and War,” The Guardian, March 13, 2015]

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.

Not-So-Random Thoughts (XII)

Links to the other posts in this occasional series may be found at “Favorite Posts,” just below the list of topics.

*     *     *

Intolerance as Illiberalism” by Kim R. Holmes (The Public Discourse, June 18, 2014) is yet another reminder, of innumerable reminders, that modern “liberalism” is a most intolerant creed. See my ironically titled “Tolerance on the Left” and its many links.

*     *     *

Speaking of intolerance, it’s hard to top a strident atheist like Richard Dawkins. See John Gray’s “The Closed Mind of Richard Dawkins” (The New Republic, October 2, 2014). Among the several posts in which I challenge the facile atheism of Dawkins and his ilk are “Further Thoughts about Metaphysical Cosmology” and “Scientism, Evolution, and the Meaning of Life.”

*     *     *

Some atheists — Dawkins among them — find a justification for their non-belief in evolution. On that topic, Gertrude Himmelfarb writes:

The fallacy in the ethics of evolution is the equation of the “struggle for existence” with the “survival of the fittest,” and the assumption that “the fittest” is identical with “the best.” But that struggle may favor the worst rather than the best. [“Evolution and Ethics, Revisited,” The New Atlantis, Spring 2014]

As I say in “Some Thoughts about Evolution,”

Survival and reproduction depend on many traits. A particular trait, considered in isolation, may seem to be helpful to the survival and reproduction of a group. But that trait may not be among the particular collection of traits that is most conducive to the group’s survival and reproduction. If that is the case, the trait will become less prevalent. Alternatively, if the trait is an essential member of the collection that is conducive to survival and reproduction, it will survive. But its survival depends on the other traits. The fact that X is a “good trait” does not, in itself, ensure the proliferation of X. And X will become less prevalent if other traits become more important to survival and reproduction.

The same goes for “bad” traits. Evolution is no guarantor of ethical goodness.

*     *     *

It shouldn’t be necessary to remind anyone that men and women are different. But it is. Lewis Wolpert gives it another try in “Yes, It’s Official, Men Are from Mars and Women from Venus, and Here’s the Science to Prove It” (The Telegraph, September 14, 2014). One of my posts on the subject is “The Harmful Myth of Inherent Equality.” I’m talking about general tendencies, of course, not iron-clad rules about “men’s roles” and “women’s roles.” Aside from procreation, I can’t readily name “roles” that fall exclusively to men or women out of biological necessity. There’s no biological reason, for example, that an especially strong and agile woman can’t be a combat soldier. But it is folly to lower the bar just so that more women can qualify as combat soldiers. The same goes for intellectual occupations. Women shouldn’t be discouraged from pursuing graduate degrees and professional careers in math, engineering, and the hard sciences, but the qualifications for entry and advancement in those fields shouldn’t be watered down just for the sake of increasing the representation of women.

*     *     *

Edward Feser, writing in “Nudge Nudge, Wink Wink” at his eponymous blog (October 24, 2014), notes

[Michael] Levin’s claim … that liberal policies cannot, given our cultural circumstances, be neutral concerning homosexuality.  They will inevitably “send a message” of approval rather than mere neutrality or indifference.

Feser then quotes Levin:

[L]egislation “legalizing homosexuality” cannot be neutral because passing it would have an inexpungeable speech-act dimension.  Society cannot grant unaccustomed rights and privileges to homosexuals while remaining neutral about the value of homosexuality.

Levin, who wrote that 30 years ago, gets a 10 out 10 for prescience. Just read “Abortion, ‘Gay Rights’, and Liberty” for a taste of the illiberalism that accompanies “liberal” causes like same-sex “marriage.”

*     *     *

“Liberalism” has evolved into hard-leftism. It’s main adherents are now an elite upper crust and their clients among the hoi polloi. Steve Sailer writes incisively about the socioeconomic divide in “A New Caste Society” (Taki’s Magazine, October 8, 2014). “‘Wading’ into Race, Culture, and IQ” offers a collection of links to related posts and articles.

*     *     *

One of the upper crust’s recent initiatives is so-called libertarian paternalism. Steven Teles skewers it thoroughly in “Nudge or Shove?” (The American Interest, December 10, 2014), a review of Cass Sunstein’s Why Nudge? The Politics of Libertarian Paternalism. I have written numerous times about Sunstein and (faux) libertarian paternalism. The most recent entry, “The Sunstein Effect Is Alive and  Well in the White House,” ends with links to two dozen related posts.

Maria Konnikova gives some space to Jonathan Haidt in “Is Social Psychology Biased against Republicans?” (The New Yorker, October 30, 2014). It’s no secret that most academic disciplines other than math and the hard sciences are biased against Republicans, conservatives, libertarians, free markets, and liberty. I have something to say about it in “The Pseudo-Libertarian Temperament,” and in several of the posts listed here.

Keith E. Stanovich makes some good points about the limitations of intelligence in “Rational and Irrational Thought: The Thinking that IQ Tests Miss” (Scientific American, January 1, 2015). Stanovich writes:

The idea that IQ tests do not measure all the key human faculties is not new; critics of intelligence tests have been making that point for years. Robert J. Sternberg of Cornell University and Howard Gardner of Harvard talk about practical intelligence, creative intelligence, interpersonal intelligence, bodily-kinesthetic intelligence, and the like. Yet appending the word “intelligence” to all these other mental, physical and social entities promotes the very assumption the critics want to attack. If you inflate the concept of intelligence, you will inflate its close associates as well. And after 100 years of testing, it is a simple historical fact that the closest associate of the term “intelligence” is “the IQ test part of intelligence.”

I make a similar point in “Intelligence as a Dirty Word,” though I don’t denigrate IQ, which is a rather reliable predictor of performance in a broad range of endeavors.

Brian Caplan, whose pseudo-libertarianism rankles, tries to defend the concept of altruism in “The Evidence of Altruism” (EconLog, December 30, 2014). Caplan aids his case by using the loaded “selfishness” where he means “self-interest.” He also ignores empathy, which is a key ingredient of the Golden Rule. As for my view of altruism (as a concept), see “Egoism and Altruism.”

Unsurprising News

John Taylor writes that “New Research Bolsters Policy Link from Uncertainty to Economy“:

Last week a joint Princeton-Stanford conference held in Princeton focused on policy uncertainty and showcased new findings on connections between policy uncertainty and political polarization and on patterns in different states, countries and time periods.

Danny Shoag, for example, presented new work “Uncertainty and the Geography of the Great Recession,” co-authored with Stan Veuger, showing that  policy uncertainty across the United States has been highly and robustly correlated with state unemployment rates. As the authors explain, their “paper serves to counter such claims” as those made by Atif Mian and Amir Sufi that “an increase in business uncertainty at the aggregate level does not explain the stark cross-sectional patterns in employment losses” which had cast doubt on the role of policy uncertainty. Scott Baker, Nick Bloom and Steve Davis had written extensively on this at the national level and also presented new work at the conference.

I’ve written about Baker, Bloom, and Davis’s work here.

Ross Douthat comments about “Diversity and Dishonesty“:

Earlier this year, a column by a Harvard undergraduate named Sandra Y. L. Korn briefly achieved escape velocity from the Ivy League bubble, thanks to its daring view of how universities should approach academic freedom.

Korn proposed that such freedom was dated and destructive, and that a doctrine of “academic justice” should prevail instead. No more, she wrote, should Harvard permit its faculty to engage in “research promoting or justifying oppression” or produce work tainted by “racism, sexism, and heterosexism.” Instead, academic culture should conform to left-wing ideas of the good, beautiful and true, and decline as a matter of principle “to put up with research that counters our goals.”

Which reminds me of the story behind Robert Putnam’s “E Pluribus Unum: Diversity and Community in the Twenty-first Century,” which I recount here. In short, Putnam withheld publication of his paper because it refutes the leftist mantra “diversity is good.”

Finally, we are told by David Z. Hambrick and Christopher Chabris that “Yes, IQ Really Matters“:

The SAT does predict success in college—not perfectly, but relatively well, especially given that it takes just a few hours to administer. And, unlike a “complex portrait” of a student’s life, it can be scored in an objective way…. In a study published in Psychological Science, University of Minnesota researchers Paul Sackett, Nathan Kuncel, and their colleagues investigated the relationship between SAT scores and college grades in a very large sample: nearly 150,000 students from 110 colleges and universities. SAT scores predicted first-year college GPA about as well as high school grades did, and the best prediction was achieved by considering both factors. Botstein, Boylan, and Kolbert are either unaware of this directly relevant, easily accessible, and widely disseminated empirical evidence, or they have decided to ignore it and base their claims on intuition and anecdote—or perhaps on their beliefs about the way the world should be rather than the way it is.

Furthermore, contrary to popular belief, it’s not just first-year college GPA that SAT scores predict. In a four-year study that started with nearly 3,000 college students, a team of Michigan State University researchers led by Neal Schmitt found that test score (SAT or ACT—whichever the student took) correlated strongly with cumulative GPA at the end of the fourth year. If the students were ranked on both their test scores and cumulative GPAs, those who had test scores in the top half (above the 50th percentile, or median) would have had a roughly two-thirds chance of having a cumulative GPA in the top half. By contrast, students with bottom-half SAT scores would be only one-third likely to make it to the top half in GPA….

[I]t is clear that [socioeconomic status] is not what accounts for the fact that SAT scores predict success in college. In the University of Minnesota study, the correlation between high school SAT and college GPA was virtually unchanged after the researchers statistically controlled for the influence of SES. If SAT scores were just a proxy for privilege, then putting SES into the mix should have removed, or at least dramatically decreased, the association between the SAT and college performance….

What this all means is that the SAT measures something—some stable characteristic of high school students other than their parents’ income—that translates into success in college. And what could that characteristic be? General intelligence….

IQ predicts many different measures of success. Exhibit A is evidence from research on job performance by the University of Iowa industrial psychologist Frank Schmidt and his late colleague John Hunter. Synthesizing evidence from nearly a century of empirical studies, Schmidt and Hunter established that general mental ability—the psychological trait that IQ scores reflect—is the single best predictor of job training success, and that it accounts for differences in job performance even in workers with more than a decade of experience. It’s more predictive than interests, personality, reference checks, and interview performance. Smart people don’t just make better mathematicians, as Brooks observed—they make better managers, clerks, salespeople, service workers, vehicle operators, and soldiers.

IQ predicts other things that matter, too, like income, employment, health, and even longevity. In a 2001 study published in the British Medical Journal, Scottish researchers Lawrence Whalley and Ian Deary identified more than 2,000 people who had taken part in the Scottish Mental Survey of 1932, a nationwide assessment of IQ. Remarkably, people with high IQs at age 11 were more considerably more likely to survive to old age than were people with lower IQs. For example, a person with an IQ of 100 (the average for the general population) was 21 percent more likely to live to age 76 than a person with an IQ of 85. And the relationship between IQ and longevity remains statistically significant even after taking SES into account. Perhaps IQ reflects the mental resources—the reasoning and problem-solving skills—that people can bring to bear on maintaining their health and making wise decisions throughout life. This explanation is supported by evidence that higher-IQ individuals engage in more positive health behaviors, such as deciding to quit smoking….

[T]he bottom line is that there are large, measurable differences among people in intellectual ability, and these differences have consequences for people’s lives. Ignoring these facts will only distract us from discovering and implementing wise policies.

Given everything that social scientists have learned about IQ and its broad predictive validity, it is reasonable to make it a factor in decisions such as whom to hire for a particular job or admit to a particular college or university. In fact, disregarding IQ—by admitting students to colleges or hiring people for jobs in which they are very likely to fail—is harmful both to individuals and to society. For example, in occupations where safety is paramount, employers could be incentivized to incorporate measures of cognitive ability into the recruitment process. Above all, the policies of public and private organizations should be based on evidence rather than ideology or wishful thinking.

As I say at the end of this post, “life just isn’t fair, so get over it.”

Race and Reason: The Achievement Gap — Causes and Implications

This is the third (and probably last) post in a series. The first two posts are “Race and Reason: The Derbyshire Debacle” and “Race and Reason: The Victims of Affirmative Action.” The purpose of the series, as suggested by the titles of the posts, is to inject reason (and facts) into the discussion of race. It has been done before, of course, but it cannot hurt to add another voice to the chorus of race-realism.

Yes, I am a race-realist. I believe (based on fact) that the socioeconomic divide between blacks and other racial-ethnic groups in America is primarily a product of genetic and cultural differences that work to the general disadvantage of blacks.

I know that some readers will quickly reject what I have to say, and a lot of them will do so as soon as they reach the end of the preceding paragraph. Why? Because the facts that I present will not comport with their view of the way the world ought to be. What is the “ought to be”? Briefly, it is an imaginary world in which all races are equal in ability, and in which cultural differences hove no bearing on economic achievement. If that is your view of the world, and if you are unwilling to consider a different, fact-based view, you may stop reading now and return to the land of unreality. Before you do that, however, I want you to be aware of one important thing: My own racial views are neutral; that is, I am unprejudiced toward blacks as blacks, though I am greatly opposed to pro-black policies (as opposed to race-neutral ones), which have been harmful to black Americans as well as their countrymen. For evidence of my race-neutrality, see the note at the bottom of this post.

Then there are those readers who might agree with the facts that I present here, but who prefer to ignore them because they might “feed racism” and be used as an excuse to treat blacks as second-class citizens. Racists need no help from me or anyone else who presents the facts about the causes of the socioeconomic divide in America. Racists are immune to facts and see the world as they think it ought to be, which is free of blacks or with blacks shunted to second-class citizenship. The socioeconomic gap between blacks and other Americans cannot be shrunk by ignoring the reasons for the gap. The gap can be shrunk (though never closed) only by understanding its real causes and adopting policies that address those causes.

A note about usage: It is my practice in this blog to put “liberal” (and its variants) in quotation marks when referring to modern liberalism, which is quite a different thing than classical liberalism. The difference, of course, is that modern liberals espouse statism. In particular, they believe that what is adjudged “good” by academic-political elites should be imposed on everyone by the state. And liberty — despite its etymological relationship to the word liberal — be damned. Thus the sarcastic quotation marks, or sneer quotes. In any event, I have, in this post, omitted the quotation marks for the sake of typographical neatness. Rest assured, however, that where I use “liberal” and its variants in this post I am referring to statists and statism.

Intelligence and Intuition

According to “Intelligence, Personality, Politics, and Happiness”, which (among other things) considers the relationship of intelligence to personality traits (as measured by the Myers-Briggs Type Indicator, MBTI),

an iNtuitive person (one who grasps patterns and seeks possibilities) is 25 times more likely to have a high IQ than a Sensing person (one who focuses on sensory details and the here-and-now).

But which comes first: intelligence or intuition? My money is on intelligence. That is, highly intelligent persons are more likely than their less intelligent peers to show up as iNtuitives on the MBTI. In my view, it is not that iNtuitives are uninterested in sensory details and the here-and-now, but — compared with Sensing persons — they more quickly grasp details and see the patterns in them and the possibilities indicated by those patterns.

In sum, I think of intuition as a manifestation of intelligence, not a cause of it. To put it another way, intuition is not an emotion; it is the opposite of emotion.

Intuition is reasoning at high speed. For example, a skilled athlete knows where and when to make a move (e.g., whether and where to swing at a pitched ball) because he subconsciously makes the necessary calculations, which he could not make consciously in the split-second that is available to him once the pitcher releases the ball.

Nature Is Unfair

The Almighty is not a liberal… The Almighty is the driving force for the entire universe and the universe is not a very liberal place. That is what the modern world seems not to understand….

Simon Mawer, The Gospel of Judas

*   *   *

Matt Ridley‘s recent article in The Wall Street Journal, “A Truce in the War Over Smarts and Genes,” is about the heritability of intelligence. The article, which is behind WSJ’s paywall, is available on Ridley’s personal website, The Rational Optimist, under the title “Goldilocks Heritability.” Here are some relevant bits:

Hardly any subject in science has been so politically fraught as the heritability of intelligence. For more than a century, since Francis Galton first started speculating about the similarities of twins, nature-nurture was a war with a stalemated front and intelligence was its Verdun—the most hotly contested and costly battle.

So would it not be rather wonderful if a scientific discovery came along that called a truce and calmed all the fury? I think this is about to happen. Call it the Goldilocks theory of intelligence: not too genetic, not too environmental—and proving that intelligence is impossible to meddle with, genetically.

The immediate cause of this optimism is a recent paper in Molecular Psychiatry, which confirms that genes account for about half of the difference in IQ between any two people in a modern society….

So far, so good. But Ridley goes off the rails with this:

…Some of the more extreme “nurturists,” especially those who dominated the debate in the 1960s to 1980s, might not welcome the new confirmation of the nearly 50% role of genes in determining IQ differences, even though it has been blindingly clear for a long time now.

They should, though. A world in which intelligence is 100% genetic would be horribly unfair….

What does “fairness” have to do with it? Is there a master gene-dispenser in the sky to whom one can complain about not having received a “fair share” of smart genes? I think not.

There would be nothing “unfair” about a world in which intelligence is 100 percent genetic. That’s just the way it would be, and nothing could — or should — be done about it.

But that wouldn’t stop leftists from trying to do something about it. As I say here,

[t]he search for cosmic justice — the rectification of all that is “unfair” in the world — is relentless, knows no bounds, and is built upon the resentment and punishment of success.

“Unfair” is the battle cry of the envious and the rabble-rouser, who derive great satisfaction from apportioning blame where no blame is due. I expect better of Ridley.

“Intelligence” As a Dirty Word

Once upon a time I read a post, “The Nature of Intelligence”,  at a now-defunct blog named MBTI Truths. Here is the entire text of the post:

A commonly held misconception within the MBTI community is that iNtuitives are smarter than Sensors. They are thought to have higher intelligence, but this belief is misguided. In an assessment of famous people with high IQs, the vast majority of them are iNtuitive. However, IQ tests measure only two types of intelligences: linguistic and logical-mathematical. In addition to these, there are six other types of intelligence: spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalistic. Sensors would probably outscore iNtuitives in several of these areas. Perhaps MBTI users should come to see iNtuitives, who make up 25 percent of the population, as having a unique type of intelligence instead of superior intelligence.

The use of “intelligence” with respect to traits other than brain-power is misguided. “Intelligence” has a clear and unambiguous meaning in everyday language; for example:

The capacity to acquire, understand, and use knowledge.

That is the way in which I use “intelligence” in “Intelligence, Personality, Politics, and Happiness”, and it is the way in which the word is commonly understood. The application of “intelligence” to other kinds of ability — musical, interpersonal, etc. — is a fairly recent development that smacks of anti-elitism. It is a way of saying that highly intelligent individuals (where “intelligence” carries its traditional meaning) are not necessarily superior in all respects. No kidding!

As to the merits of the post at MBTI Truths, it is mere hand-waving to say that “Sensors would probably outscore iNtuitives in several of these” other types of ability. And what is naturalistic intelligence, anyway?

Returning to a key point of my post, “Intelligence, Personality, Politics, and Happiness”, the claim that iNtuitives are generally smarter than Sensors is nothing but a claim about the relative capacity of iNtuitives to acquire and apply knowledge. It is quite correct to say that iNtuitives are not necessarily better than Sensors at, say, sports, music, glad-handing, and so one. It is also quite correct to say that iNtuitives generally are more intelligent than Sensors, in the standard meaning of “intelligence”.

Other so-called types of intelligence are not types of intelligence, at all. They are simply other types of ability, each of them is (perhaps) valuable in its own way. But calling them types of intelligence is a transparent effort to denigrate the importance of real intelligence, which is an important determinant of significant life outcomes: learning, job performance, income, health, and criminality (in the negative).

It is a sign of the times that an important human trait is played down in an effort to inflate the egos of persons who are not well endowed with respect to that trait. The attempt to redefine or minimize intelligence is of a piece with the use of genteelisms, which Wilson Follett defines as

soft-spoken expressions that are either unnecessary or too regularly used. The modern world is much given to making up euphemisms that turn into genteelisms. Thus newspapers and politicians shirk speaking of the poor and the crippled. These persons become, respectively, the underprivileged (or disadvantaged) and the handicapped [and now -challenged and -abled: ED]. (Modern American Usage (1966), p. 169)

Finally:

Genteelisms may be of … the old-fashioned sort that will not name common things outright, such as the absurd plural bosoms for breasts, and phrases that try to conceal accidental associations of ideas, such as back of for behind. The advertiser’s genteelisms are too numerous to count. They range from the false comparative (e.g., the better hotels) to the soapy phrase (e.g., gracious living), which is supposed to poeticize and perfume the proffer of bodily comforts. (Ibid., p. 170)

And so it is that such traits as athleticism, musical virtuosity, and garrulousness become kinds of intelligence. Why? Because it is somehow inegalitarian — and therefore unmentionable — that some persons are smarter than others. It would be doubly inegalitarian — but likely true — that smarter persons also have genetic tendencies to greater health and physical attractiveness.

Life just isn’t fair, so get over it.

Intelligence, Personality, Politics, and Happiness

Web pages that link to this post usually consist of a discussion thread whose participants’ views of the post vary from “I told you so” to “that doesn’t square with me/my experience” or “MBTI is all wet because…”.  Those who take the former position tend to be persons of above-average intelligence whose MBTI types correlate well with high intelligence. Those who take the latter two positions tend to be persons who are defensive about their personality types, which do not correlate well with high intelligence. Such persons should take a deep breath and remember that high intelligence (of the abstract-reasoning-book-learning kind measured by IQ tests) is widely distributed throughout the population. As I say below, ” I am not claiming that a small subset of MBTI types accounts for all high-IQ persons, nor am I claiming that a small subset of MBTI types is populated entirely by high-IQ persons.” All I am saying is that the bits of evidence which I have compiled suggest that high intelligence is more likely — but far from exclusively — to be found among persons with certain MBTI types.

The correlations between intelligence, political leanings, and happiness are admittedly more tenuous. But they are plausible.

Leftists who proclaim themselves to be more intelligent than persons of the right do so, in my observation, as a way of reassuring themselves of the superiority of their views. They have no legitimate basis for claiming that the ranks of highly intelligent persons are dominated by the left. Leftist “intellectuals” in academia, journalism, the “arts”, and other traditional haunts of leftism are prominent because they are vocal. But they comprise a small minority of the population and should not be mistaken for typical leftists, who seem mainly to populate the ranks of the civil service, labor unions, public-school “educators”, and the unemployed. (It is worth noting that public-school teachers, on the whole, are notoriously dumber than most other college graduates.)

Again, I am talking about general relationships, to which there are many exceptions. If you happen to be an exception, don’t take this post personally. You’re probably an exceptional person.

IQ AND PERSONALITY

Some years ago I found statistics about the personality traits of high-IQ persons (those who are in the top 2 percent of the population).* The statistics pertain to a widely used personality test called the Myers-Briggs Type Indicator (MBTI), which I have taken twice. In the MBTI there are four pairs of complementary personality traits, called preferences: Extraverted/Introverted, Sensing/iNtuitive, Thinking/Feeling, and Judging/Perceiving. Thus, there are 16 possible personality types in the MBTI: ESTJ, ENTJ, ESFJ, ESFP, and so on. (For an introduction to MBTI, summaries of types, criticisms of MBTI, and links to other sources, see this article at Wikipedia. A straightforward description of the theory of MBTI and the personality traits can be found here. Detailed descriptions of the 16 types are given here.)

In summary, here is what the statistics indicate about the correlation between personality traits and IQ:

  • Other personality traits being the same, an iNtuitive person (one who grasps patterns and seeks possibilities) is 25 times more likely to have a high IQ than a Sensing person (one who focuses on sensory details and the here-and-now).
  • Again, other traits being the same, an Introverted person is 2.6 times more likely to have a high IQ than one who is Extraverted; a Thinking (logic-oriented) person is 4.5 times more likely to have a high IQ than a Feeling (people-oriented) person; and a Judging person (one who seeks closure) is 1.6 times as likely to have a high IQ than a Perceiving person (one who likes to keep his options open).
  • Moreover, if you encounter an INTJ, there is a 22% probability that his IQ places him in the top 2 percent of the population. (Disclosure: I am an INTJ.) Next are INTP, at 14%; ENTJ, 8%; ENTP, 5%; and INFJ, 5%. (The next highest type is the INFP at 3%.) The  five types (INTJ, INTP, ENTJ, ENTP, and INFJ) account for 78% of the high-IQ population but only 15% of the total population.**
  • Four of the five most-intelligent types are NTs, as one would expect, given the probabilities cited above. Those same probabilities lead to the dominance of INTJs and INTPs, which account for 49% of the Mensa membership but only 5% of the general population.**
  • Persons with the S preference bring up the rear, when it comes to taking IQ tests.**

A person who read an earlier version of this post claims that “one would expect to see the whole spectrum of intelligences within each personality type.” Well, one does see just that, but high intelligence is skewed toward the five types listed above. I am not claiming that a small subset of MBTI types accounts for all high-IQ persons, nor am I claiming that a small subset of MBTI types is populated entirely by high-IQ persons.

I acknowledge reservations about MBTI, such as those discussed in the Wikipedia article. An inherent shortcoming of psychological tests (as opposed to intelligence tests) is that they rely on subjective responses (e.g., my favorite color might be black today and blue tomorrow). But I do not accept this criticism:

[S]ome researchers expected that scores would show a bimodal distribution with peaks near the ends of the scales, but found that scores on the individual subscales were actually distributed in a centrally peaked manner similar to a normal distribution. A cut-off exists at the center of the subscale such that a score on one side is classified as one type, and a score on the other side as the opposite type. This fails to support the concept of type: the norm is for people to lie near the middle of the subscale.

Why was it expected that scores on a subscale (E/I, S/N, T/F, J/P) would show a bimodal distribution? How often does one encounter a person who is at the extreme end of any subscale? Not often, I wager, except in places where such extremes are likely to be clustered (e.g., Extraverts in politics, Introverts in monasteries). The cut-off at the center of each subscale is arbitrary; it simply affords a shorthand characterization of a person’s dominant traits. But anyone who takes an MBTI (or equivalent instrument) is given his scores on each of the subscales, so that he knows the strength (or weakness) of his tendencies.

Regarding other points of criticism: It is possible, of course, that a person who is familiar with MBTI tends to see in others the characteristics of their known MBTI types (i.e., confirmation bias). But has that tendency been confirmed by rigorous testing? Such testing would examine the contrary case, that is, the ability of a person to predict the type of a person whom he knows well (e.g., a co-worker or relative).

The supposed vagueness of the descriptions of the 16 types arises from the complexity of human personality; but there are differences among the descriptions, just as there are differences among individuals. According to a footnote to an earlier version of the Wikipedia article about MBTI, half of the persons who take the MBTI are able to guess their types before taking it. Does that invalidate MBTI or does it point to a more likely phenomenon, namely, that introspection is a personality-related trait, one that is more common among Introverts than Extraverts? A good MBTI instrument cuts through self-deception and self-flattery by asking the same set of questions in many different ways, and in ways that do not make any particular answer seem like the “right” one.

IQ AND POLITICS

It is hard to find clear, concise analyses of the relationship between IQ and political leanings. I offer the following in evidence that very high-IQ individuals lean strongly toward libertarian positions.

The Triple Nine Society (TNS) limits its membership to persons with IQs in the top 0.1% of the population. In an undated survey (probably conducted in 2000, given the questions about the perceived intelligence of certain presidential candidates), members of TNS gave their views on several topics (in addition to speculating about the candidates’ intelligence): subsidies, taxation, civil regulation, business regulation, health care, regulation of genetic engineering, data privacy, death penalty, and use of military force.

The results speak for themselves. Those members of TNS who took the survey clearly have strong (if not unanimous) libertarian leanings.

THE RIGHT IS SMARTER THAN THE LEFT

I count libertarians as part of the right because libertarians’ anti-statist views are aligned with the views of the traditional (small-government) conservatives who are usually Republicans. Having said that, the results reported in “IQ and Politics” lead me to suspect that the right is smarter than the left, left-wing propaganda to the contrary notwithstanding. There is additional evidence for my view.

A site called Personality Page offers some data about personality type and political affiliation. The sample is not representative of the population as a whole; the average age of respondents is 25, and introverted personalities are over-represented (as you might expect for a test that is apparently self-administered through a website). On the other hand, the results are probably unbiased with respect to intelligence because the data about personality type were not collected as part of a study that attempts to relate political views and intelligence, and there is nothing on the site to indicate a left-wing bias. (Psychologists, who tend toward leftism, have a knack for making conservatives look bad, as discussed here, here, and here. If there is a strong association between political views and intelligence, it is found among so-called intellectuals, where the herd mentality reigns supreme.)

The data provided by Personality Page are based on the responses of 1,222 individuals who took a 60-question personality test that determined their MBTI types (see “IQ and Personality”). The test takers were asked to state their political preferences, given these choices: Democrat, Republican, middle of the road, liberal, conservative, libertarian, not political, and other. Political self-labelling is an exercise in subjectivity. Nevertheless, individuals who call themselves Democrats or liberals (the left) are almost certainly distinct, politically, from individuals who call themselves Republicans, conservatives, or libertarians (the right).

Now, to the money question: Given the distribution of personality types on the left and right, which distribution is more likely to produce members of Mensa? The answer: Those who self-identify as persons of the right are 15 percent more likely to qualify for membership in Mensa than those who self-identify as persons of the left. This result is plausible because it is consistent with the pronounced anti-government tendencies of the very-high-IQ members of the Triple Nine Society (see “IQ and Politics”).

REPUBLICANS (AND LIBERTARIANS) ARE HAPPIER THAN DEMOCRATS

That statement follows from research by the Pew Research Center (“Are We Happy Yet?”, February 13, 2006) and Gallup (“Republicans Report Much Better Health Than Others”, November 30, 2007).

Pew reports:

Some 45% of all Republicans report being very happy, compared with just 30% of Democrats and 29% of independents. This finding has also been around a long time; Republicans have been happier than Democrats every year since the General Social Survey began taking its measurements in 1972….

Of course, there’s a more obvious explanation for the Republicans’ happiness edge. Republicans tend to have more money than Democrats, and — as we’ve already discovered — people who have more money tend to be happier.

But even this explanation only goes so far. If one controls for household income, Republicans still hold a significant edge: that is, poor Republicans are happier than poor Democrats; middle-income Republicans are happier than middle-income Democrats, and rich Republicans are happier than rich Democrats.

Gallup adds this:

Republicans are significantly more likely to report excellent mental health than are independents or Democrats among those making less than $50,000 a year, and among those making at least $50,000 a year. Republicans are also more likely than independents and Democrats to report excellent mental health within all four categories of educational attainment.

There is a lot more in both sources. Read them for yourself.

Why would Republicans be happier than Democrats? Here’s my thought, Republicans tend to be conservative or libertarian (at least with respect to minimizing government’s role in economic affairs). Consider Thomas Sowell’s A Conflict of Visions:

He posits two opposing visions: the unconstrained vision (I would call it the idealistic vision) and the constrained vision (which I would call the realistic vision). As Sowell explains, at the end of chapter 2:

The dichotomy between constrained and unconstrained visions is based on whether or not inherent limitations of man are among the key elements included in each vision…. These different ways of conceiving man and the world lead not merely to different conclusions but to sharply divergent, often diametrically opposed, conclusions on issues ranging from justice to war.

Idealists (“liberals”) are bound to be less happy than realists (conservatives and libertarians) because idealists’ expectations about human accomplishments (aided by government) are higher than those of realists, and so idealists are doomed to disappointment.

All of this is consistent with findings reported by law professor James Lindgren:

[C]ompared to anti-redistributionists, strong redistributionists have about two to three times higher odds of reporting that in the prior seven days they were angry, mad at someone, outraged, sad, lonely, and had trouble shaking the blues. Similarly, anti-redistributionists had about two to four times higher odds of reporting being happy or at ease. Not only do redistributionists report more anger, but they report that their anger lasts longer. When asked about the last time they were angry, strong redistributionists were more than twice as likely as strong opponents of leveling to admit that they responded to their anger by plotting revenge. Last, both redistributionists and anti-capitalists expressed lower overall happiness, less happy marriages, and lower satisfaction with their financial situations and with their jobs or housework.

THE BOTTOM LINE

If you are very intelligent — with an IQ that puts you in the top 2 percent of the population — you are most likely to be an INTJ, INTP, ENTJ, ENTP, or INFJ, in that order. Your politics will lean heavily toward libertarianism or small-government conservatism. You probably vote Republican most of the time because, even if you are not a card-carrying Republican, you are a staunch anti-Democrat. And you are a happy person because your expectations are not constantly defeated by reality.

Footnotes:

* I apologize for not having documented the source of the statistics that I cite here. I dimly recall finding them on or via the website of American Mensa, but I am not certain of that. And I can no longer find the source by searching the web. I did transcribe the statistics to a spreadsheet, which I still have. So, the numbers are real, even if their source is now lost to me.

** Estimates of the distribution of  MBTI types  in the U.S. population are given in two tables on page 4 of “Estimated Frequencies of the Types in the United States Population”, published by the Center for Applications of Psychological Type. One table gives estimates of the distribution of the population by preference (E, I, N, S, etc.). The other table give estimates of the distribution of the population among all 16 MBTI types. The statistics for members of Mensa were broken down by preferences, not by types; therefore I had to use the values for preferences to estimate the frequencies of the 16 types among members of Mensa. For consistency, I used the distribution of the preferences among the U.S. population to estimate the frequencies of the 16 types among the population, rather than use the frequencies provided for each type. For example, the fraction of the population that is INTJ comes to 0.029 (2.9 percent) when the values for I (0.507), N (0.267), T (0.402), and J (0.541) are multiplied. But the detailed table has INTJs as 2.1 percent of the population. In sum, there are discrepancies between the computed and given values of the 16 types in the population. The most striking discrepancy is for the INFJ type. When estimated from the frequencies of the four preferences, INFJs are 4.4 percent of the population; the table of values for all 16 types gives the percentage of INFJs as 1.5 percent.

Using the distribution given for the 16 types leads to somewhat different results:

  • There is a 31-percent probability that an INTJ’s IQ places him in the top 2 percent of the population. Next are INFJ, at 14 percent; ENTJ, 13 percent; and INTP, 10 percent. (The next highest type is the ENTP at 4 percent.) The  four types (INTJ, INFJ, ENTJ, AND INTP) account for 72 percent of the high-IQ population but only 9 percent of the total population. The top five types (including ENTPs) account for 78 percent of the high-IQ population but only 12 percent of the total population.
  • Four of the five most-intelligent types are NTs, as one would expect, given the probabilities cited earlier. But, in terms of the likelihood of having an IQ, this method moves INFJs into second place, a percentage point ahead of ENTJs.
  • In any event, the same five types dominate, and all five types have a preference for iNtuitive thinking.
  • As before, persons with the S preference generally lag their peers when it comes to IQ tests.

Color Me Unsurprised…

…by this, from Daniel Klein:

Zogby researcher Zeljka Buturovic and I considered the 4,835 respondents’ (all American adults) answers to eight survey questions about basic economics. We also asked the respondents about their political leanings: progressive/very liberal; liberal; moderate; conservative; very conservative; and libertarian….

How did the six ideological groups do overall? Here they are, best to worst, with an average number of incorrect responses from 0 to 8: Very conservative, 1.30; Libertarian, 1.38; Conservative, 1.67; Moderate, 3.67; Liberal, 4.69; Progressive/very liberal, 5.26….

The survey also asked about party affiliation. Those responding Democratic averaged 4.59 incorrect answers. Republicans averaged 1.61 incorrect, and Libertarians 1.26 incorrect. (“Are You Smarter Than a Fifth-Grader?The Wall Street Journal, June 8, 2010)

Part of the explanation, of course, is that “liberals” and “progressives” derive their view of the world from their emotions: “It ought to be that way, so that’s the way it is.” Another part of the explanation is that “liberals” and “progressives” just aren’t as smart or rational as they like to think they are:

IQ and Personality
IQ and Politics
The Right Is Smarter Than the Left
The Psychology of Extremism

I wouldn’t mind it if the hubris of “liberals” and “progressives” led them to a nasty end, but they have acquired the power to take the rest of us with them.
