Analytical and Scientific Arrogance

It is customary in democratic countries to deplore expenditures on armaments as conflicting with the requirements of the social services. There is a tendency to forget that the most important social service that a government can do for its people is to keep them alive and free.

Marshal of the Royal Air Force Sir John Slessor, Strategy for the West

I’m returning to the past to make a timeless point: Analysis is a tool of decision-making, not a substitute for it.

That’s a point to which every analyst will subscribe, just as every judicial candidate will claim to revere the Constitution. But analysts past and present have tended to read their policy preferences into their analytical work, just as too many judges real their political preferences into the Constitution.

What is an analyst? Someone whose occupation requires him to gather facts bearing on an issue, discern robust relationships among the facts, and draw conclusions from those relationships.

Many professionals — from economists to physicists to so-called climate scientists — are more or less analytical in the practice of their professions. That is, they are not just seeking knowledge, but seeking to influence policies which depend on that knowledge.

There is also in this country (and in the West, generally) a kind of person who is an analyst first and a disciplinary specialist second (if at all). Such a person brings his pattern-seeking skills to the problems facing decision-makers in government and industry. Depending on the kinds of issues he addresses or the kinds of techniques that he deploys, he may be called a policy analyst, operations research analyst, management consultant, or something of that kind.

It is one thing to say, as a scientist or analyst, that a certain option (a policy, a system, a tactic) is probably better than the alternatives, when judged against a specific criterion (most effective for a given cost, most effective against a certain kind of enemy force). It is quite another thing to say that the option is the one that the decision-maker should adopt. The scientist or analyst is looking a small slice of the world; the decision-maker has to take into account things that the scientist or analyst did not (and often could not) take into account (economic consequences, political feasibility, compatibility with other existing systems and policies).

It is (or should be) unsconsionable for a scientist or analyst to state or imply that he has the “right” answer. But the clever arguer avoids coming straight out with the “right” answer; instead, he slants his presentation in a way that makes the “right” answer seem right.

A classic case in point is they hysteria surrounding the increase in “global” temperature in the latter part of the 20th century, and the coincidence of that increase with the rise in CO2. I have had much to say about the hysteria and the pseudo-science upon which it is based. (See links at the end of this post.) Here, I will take as a case study an event to which I was somewhat close: the treatment of the Navy’s proposal, made in the early 1980s, for an expansion to what was conveniently characterized as the 600-ship Navy. (The expansion would have involved personnel, logistics systems, ancillary war-fighting systems, stockpiles of parts and ammunition, and aircraft of many kinds — all in addition to a 25-percent increase in the number of ships in active service.)

The usual suspects, of an ilk I profiled here, wasted no time in making the 600-ship Navy seem like a bad idea. Of the many studies and memos on the subject, two by the Congressional Budget Office stand out a exemplars of slanted analysis by innuendo: “Building a 600-Ship Navy: Costs, Timing, and Alternative Approaches” (March 1982), and “Future Budget Requirements for the 600-Ship Navy: Preliminary Analysis” (April 1985). What did the “whiz kids” at CBO have to say about the 600-ship Navy? Here are excerpts of the concluding sections:

The Administration’s five-year shipbuilding plan, containing 133 new construction ships and estimated to cost over $80 billion in fiscal year 1983 dollars, is more ambitious than previous programs submitted to the Congress in the past few years. It does not, however, contain enough ships to realize the Navy’s announced force level goals for an expanded Navy. In addition, this plan—as has been the case with so many previous plans—has most of its ships programmed in the later out-years. Over half of the 133 new construction ships are programmed for the last two years of the five-year plan. Achievement of the Navy’s expanded force level goals would require adhering to the out-year building plans and continued high levels of construction in the years beyond fiscal year 1987. [1982 report, pp. 71-72]

Even the budget increases estimated here would be difficult to achieve if history is a guide. Since the end of World War II, the Navy has never sustained real increases in its budget for more than five consecutive years. The sustained 15-year expansion required to achieve and sustain the Navy’s present plans would result in a historic change in budget trends. [1985 report, p. 26]

The bias against the 600-ship Navy drips from the pages. The “argument” goes like this: If it hasn’t been done, it can’t be done and, therefore, shouldn’t be attempted. Why not? Because the analysts at CBO were a breed of cat that emerged in the 1960s, when Robert Strange McNamara and his minions used simplistic analysis (“tablesmanship”) to play “gotcha” with the military services:

We [I was one of the minions] did it because we were encouraged to do it, though not in so many words. And we got away with it, not because we were better analysts — most of our work was simplistic stuff — but because we usually had the last word. (Only an impassioned personal intercession by a service chief might persuade McNamara to go against SA [the Systems Analysis office run by Alain Enthoven] — and the key word is “might.”) The irony of the whole process was that McNamara, in effect, substituted “civilian judgment” for oft-scorned “military judgment.” McNamara revealed his preference for “civilian judgment” by elevating Enthoven and SA a level in the hierarchy, 1965, even though (or perhaps because) the services and JCS had been open in their disdain of SA and its snotty young civilians.

In the case of the 600-ship Navy, civilian analysts did their best to derail it by sending the barely disguised message that it was “unaffordable”. I was reminded of this “insight” by a colleague of long-standing who recently proclaimed that “any half-decent cost model would show a 600-ship Navy was unsustainable into this century.” How could a cost model show such a thing when the sustainability (affordability) of defense is a matter of political will, not arithmetic?

Defense spending fluctuates as function of perceived necessity. Consider, for example, this graph (misleadingly labeled “Recent Defense Spending”) from usgovernmentspending.com, which shows defense spending as a percentage of GDP for fiscal year (FY) 1792 to FY 2017:

What was “unaffordable” before World War II suddenly became affordable. And so it has gone throughout the history of the republic. Affordability (or sustainability) is a political issue, not a line drawn in the sand by an smart-ass analyst who gives no thought to the consequences of spending too little on defense.

I will now zoom in on the era of interest.

CBO’s “Building a 600-Ship Navy: Costs, Timing, and Alternative Approaches“, which crystallized opposition to the 600-ship Navy estimates the long-run, annual obligational authority required to sustain a 600-ship Navy (of the Navy’s design) to be about 20-percent higher in constant dollars than the FY 1982 Navy budget. (See Options I and II in Figure 2, p. 50.) The long-run would have begun around FY 1994, following several years of higher spending associated with the buildup of forces. I don’t have a historical breakdown of the Department of Defense (DoD) budget by service, but I found values for all-DoD spending on military programs at Office of Management and Budget Historical Tables. Drawing on Tables 5.2 and 10.1, I constructed a constant-dollar of DoD’s obligational authority (FY 1982 = 1):

There was no inherent reason that defense spending couldn’t have remained on the trajectory of the middle 1980s. The slowdown of the late 1980s was a reflection of improved relations between the U.S. and USSR. Those improved relations had much to do with the Reagan defense buildup, of which the goal of attaining a 600-ship Navy was an integral part.

The Reagan buildup helped to convince Soviet leaders (Gorbachev in particular) that trying to keep pace with the U.S. was futile and (actually) unaffordable. The rest — the end of the Cold War and the dissolution of the USSR — is history. The buildup, in other words, sowed the seeds of its own demise. But that couldn’t have been predicted with certainty in the early-to-middle 1980s, when CBO and others were doing their best to undermine political support for more defense spending. Had CBO and the other nay-sayers succeeded in their aims, the Cold War and the USSR might still be with us.

The defense drawdown of the mid-1990s was a deliberate response to the end of the Cold War and lack of other serious threats, not a historical necessity. It was certainly not on the table in the early 1980s, when the 600-ship Navy was being pushed. Had the Cold War not thawed and ended, there is no reason that U.S. defense spending couldn’t have continued at the pace of the middle 1980s, or higher. As is evident in the index values for recent years, even after drastic force reductions in Iraq, defense spending is now about one-third higher than it was in FY 1982.

John Lehman, Secretary of the Navy from 1981 to 1987, was rightly incensed that analysts — some of them on his payroll as civilian employees and contractors — were, in effect, undermining a deliberate strategy of pressing against a key Soviet weakness — the unsustainability of its defense strategy. There was much lamentation at the time about Lehman’s “war” on the offending parties, one of which was the think-tank for which I then worked. I can now admit openly that I was sympathetic to Lehman and offended by the arrogance of analysts who believed that it was their job to suggest that spending more on defense was “unaffordable”.

When I was a young analyst I was handed a pile of required reading material. One of the items was was Methods of Operations Research, by Philip M. Morse and George E. Kimball. Morse, in the early months of America’s involvement in World War II, founded the civilian operations-research organization from which my think-tank evolved. Kimball was a leading member of that organization. Their book is notable not just a compendium of analytical methods that were applied, with much success, to the war effort. It is also introspective — and properly humble — about the power and role of analysis.

Two passages, in particular, have stuck with me for the more than 50 years since I first read the book. Here is one of them:

[S]uccessful application of operations research usually results in improvements by factors of 3 or 10 or more…. In our first study of any operation we are looking for these large factors of possible improvement…. They can be discovered if the [variables] are given only one significant figure,…any greater accuracy simply adds unessential detail.

One might term this type of thinking “hemibel thinking.” A bel is defined as a unit in a logarithmic scale corresponding to a factor of 10. Consequently a hemibel corresponds to a factor of the square root of 10, or approximately 3. [p. 38]

Morse and Kimball — two brilliant scientists and analysts, who had worked with actual data (pardon the redundancy) about combat operations — counseled against making too much of quantitative estimates given the uncertainties inherent in combat. But, as I have seen over the years, analysts eager to “prove” something nevertheless make a huge deal out of minuscule differences in quantitative estimates — estimates based not on actual combat operations but on theoretical values derived from models of systems and operations yet to see the light of day. (I also saw, and still see, too much “analysis” about soft subjects, such as domestic politics and international relations. The amount of snake oil emitted by “analysts” — sometimes called scholars, journalists, pundits, and commentators — would fill the Great Lakes. Their perceptions of reality have an uncanny way of supporting their unabashed decrees about policy.)

The second memorable passage from Methods of Operations Research goes directly to the point of this post:

Operations research done separately from an administrator in charge of operations becomes an empty exercise. [p. 10].

In the case of CBO and other opponents of the 600-ship Navy, substitute “cost estimate” for “operations research”, “responsible defense official” for “administrator in charge”, and “strategy” for “operations”. The principle is the same: The CBO and its ilk knew the price of the 600-ship Navy, but had no inkling of its value.

Too many scientists and analysts want to make policy. On the evidence of my close association with scientists and analysts over the years — including a stint as an unsparing reviewer of their products — I would say that they should learn to think clearly before they inflict their views on others. But too many of them — even those with Ph.D.s in STEM disciplines — are incapable of thinking clearly, and more than capable of slanting their work to support their biases. Exhibit A: Michael Mann, James Hansen (more), and their co-conspirators in the catastrophic-anthropogenic-global-warming scam.

Defense Spending, One More Time

A long-time friend, who for 40 years worked in and for the Pentagon, advances a rationale for defense budget-cutting that, I fear, is all-too prevalent: A defense budget that matches or exceeding the Cold War’s shouldn’t be needed when the threat of global war has receded so much.

A more complete (honest) version reads like this: The U.S. defense budget should be large enough — despite errors of intelligence, allocation, and execution, and despite the vagaries of war — to defeat a determined and skillful enemy, should that enemy not be deterred by its perceptions of U.S. military strength, the willingness of U.S. leaders to wield that strength, and their skill in doing so.

When spelled out in that way, it’s more obvious that the judgments involved in deciding the requisite size of the U.S. defense budget (let alone its allocation) are largely subjective. That is, knowing “how much is enough” was a grossly uncertain undertaking during the Cold War. So grossly uncertain that the level of U.S. defense spending during the Cold War can’t be used as a valid benchmark for U.S. defense spending in the future. All we know about Cold War defense spending is that it was adequate to deter (and probably defeat) a Potemkin-like Soviet military. We don’t know (and never can know) if it would have been adequate to the task of deterring and defeating the Soviet military that it was intended to deter and defeat.

Moreover, the formulation omits a crucial consideration. Reductions in the U.S. defense budget invite ambitious, aggressive regimes to build enough military strength to (a) deter a weaker U.S. from contesting limited military adventures that could harm U.S. interests and (b) badly damage U.S. forces deployed to contest such military adventures, with the aim of forcing U.S. withdrawal pursuant to media-orchestrated domestic backlash (as in Vietnam, Lebanon, Somalia, and Iraq).

In sum, there is no real case for the reduction of defense spending after the so-called victory in the Cold War. Indeed, the very act of cutting the U.S. defense budget invites anti-American adventurism while weakening the ability of U.S. leaders to respond to it, and therefore weakening their willingness to respond to it. The cases of Vietnam, Lebanon, and Somalia reveal a preference among post-World War II American leaders for withdrawal in the face of tenacious opposition — a concept foreign to Abraham Lincoln and Winston Churchill. That preference was duly noted in Osama bin Laden’s 1996 fatwa against the United States.

What about the fact that the U.S. — despite a lot of budget cutting — hasn’t been threatened by a truly powerful adversary since the end of the Cold War? The problem is that force reductions and force buildups aren’t time-symmetrical. Forces can be cut quickly, but can’t be reconstituted and returned to fighting shape nearly as quickly.

Unfortunately, however, war usually comes more quickly than expected, if not unexpectedly. Consider the Japanese attack on Pearl Harbor of December 7, 1941; the North Korean invasion of South Korea on June 25, 1950; and the terrorist attacks of September 11, 2001. Yes, given the evidence at hand, the U.S. should have been better prepared for those events. But unpreparedness seems to be a systemic feature of America’s squabbling, interest-group based, multi-headed, media-sensitive political “system.” This argues for a permanently high level of preparedness, attained (somehow) despite the “system.”

I’ll end on that tantalizing note.

Delusions of Preparedness

The current push to trim the defense budget is foolish on two counts. First, the huge deficits projected for the federal government arise mainly from commitments to continue and expand three major entitlement programs: Social Security, Medicare, and Medicaid (Obamacare represents an expansion of all three). Second, the defense budget should be geared to external threats, not to the federal government’s fiscal problems. Cutting the defense budget to fund profligate spending on “social services” is like preparing for a street brawl by spending money on a new suit instead of brass knuckles.

There is, nevertheless, a tendency in political-punditry circles to bemoan the amounts spent on defense. Anti-defense zealots get it into their heads that the government spends “too much” on defense — period. What they mean, of course, is that the government spends money to execute wars of which they disapprove, and to prepare for wars that they would rather not think about. There is also the fear — now that the looming bankruptcy of entitlement programs cannot be denied — that money will be taken from “social services” rather than defense.

On that score, it is well to remember the words of Marshal of the Royal Air Force Sir John Slessor:

It is customary in democratic countries to deplore expenditures on armaments as conflicting with the requirements of the social services. There is a tendency to forget that the most important social service that a government can do for its people is to keep them alive and free.

Rather than take money from defense, our “leaders” should be thinking about how to spend more on defense. Nothing is more inviting to an aggressor than his intended victim’s lack of preparedness.

A common mistake, even among students of war, is to assume that there will be time to mobilize American’s economic engine, as in World War II. But that was before the advent of nuclear weapons, long-range missiles, and the ability of terrorists and cyber-warriors to create economic and military chaos. I submit that America’s strength vis-a-vis its actual and potential enemies now requires the following:

1. secured/hardened/redundant telecommunications (including internet), transportation, and energy networks

2. effective strategic and tactical intelligence (necessarily more intrusive than desired by civil-liberties purists)

3. quick response (at home and abroad) to tactical intelligence via special operations units (including some that can respond in kind to cyber-attacks)

4. a large “standing army,” with a broad range of strategic and conventional forces that are fully manned and trained, well-maintained and supplied, and technologically advanced — to deter and, as necessary, fight hostile regimes that pose threats to Americans and their overseas interests.

It is my sense that our current and planned defenses do not measure up to those requirements. The talk of cutting the defense budget should be scuttled, as should the “social services” that are the real cause of the government’s fiscal problems.
