[Epistemic status: a middling argument]

A few months ago, I wrote about how RAND, and the “Defense Intellectuals” of the cold war represent another precious datapoint of “very smart people, trying to prevent the destruction of the world, in a civilization that they acknowledge to be inadequate to dealing sanely with x-risk.”

Since then I spent some time doing additional research into what cognitive errors and mistakes  those consultants, military officials, and politicians made that endangered the world. The idea being that if we could diagnose which specific irrationalities they were subject to, that this would suggest errors that might also be relevant to contemporary x-risk mitigators, and might point out some specific areas where development of rationality training is needed.

However, this proved somewhat less fruitful than I was hoping, and I’ve put it aside for the time being. I might come back to it in the coming months.

It does seem worth sharing at least one relevant anecdote, from Daniel Ellsberg’s excellent book, the Doomsday Machine, and analysis, given that I’ve already written it up.

The missile gap

In the late nineteen-fifties it was widely understood that there was a “missile gap”: that the soviets had many more ICBM (“intercontinental ballistic missiles” armed with nuclear warheads) than the US.

Estimates varied widely on how many missiles the soviets had. The Army and the Navy gave estimates of about 40 missiles, which was about at parity with the the US’s strategic nuclear force. The Air Force and the Strategic Air Command, in contrast, gave estimates of as many as 1000 soviet missiles, 20 times more than the US’s count.

(The Air Force and SAC were incentivized to inflate their estimates of the Russian nuclear arsenal, because a large missile gap strongly necessitated the creation of more nuclear weapons, which would be under SAC control and entail increases in the Air Force budget. Similarly, the Army and Navy were incentivized to lowball their estimates, because a comparatively weaker soviet nuclear force made conventional military forces more relevant and implied allocating budget-resources to the Army and Navy.)

So there was some dispute about the size of the missile gap, including an unlikely possibility of nuclear parity with the Soviet Union. Nevertheless, the Soviet’s nuclear superiority was the basis for all planning and diplomacy at the time.

Kennedy campaigned on the basis of correcting the missile gap. Perhaps more critically, all of RAND’s planning and analysis was concerned with the possibility of the Russians launching a nearly-or-actually debilitating first or second strike.

The revelation

In 1961 it came to light, on the basis of new satellite photos, that all of these estimates were dead wrong. It turned out the the Soviets had only 4 nuclear ICBMs, one tenth as many as the US controlled.

The importance of this development should be emphasized. It meant that several of the fundamental assumptions of US nuclear planners were in error.

First of all, it meant that the Soviets were not bent on world domination (as had been assumed). Ellsberg says…

Since it seemed clear that the Soviets could have produced and deployed many, many more missiles in the three years since their first ICBM test, it put in question—it virtually demolished—the fundamental premise that the Soviets were pursuing a program of world conquest like Hitler’s.

…

That pursuit of world domination would have given them an enormous incentive to acquire at the earliest possible moment the capability to disarm their chief obstacle to this aim, the United States and its SAC. [That] assumption of Soviet aims was shared, as far as I knew, by all my RAND colleagues and with everyone I’d encountered in the Pentagon:

The Assistant Chief of Staff, Intelligence, USAF, believes that Soviet determination to achieve world domination has fostered recognition of the fact that the ultimate elimination of the US, as the chief obstacle to the achievement of their objective, cannot be accomplished without a clear preponderance of military capability.

If that was their intention, they really would have had to seek this capability before 1963. The 1959–62 period was their only opportunity to have such a disarming capability with missiles, either for blackmail purposes or an actual attack. After that, we were programmed to have increasing numbers of Atlas and Minuteman missiles in hard silos and Polaris sub-launched missiles. Even moderate confidence of disarming us so thoroughly as to escape catastrophic damage from our response would elude them indefinitely.

Four missiles in 1960–61 was strategically equivalent to zero, in terms of such an aim.

This revelation about soviet goals was not only of obvious strategic importance, it also took the wind out of the ideological motivation for this sort of nuclear planning. As Ellsberg relays early in his book, many, if not most, RAND employees were explicitly attempting to defend US and the world from what was presumed to be an aggressive communist state, bent on conquest. This just wasn’t true.

But it had even more practical consequences: this revelation meant that the Russians had no first strike (or for that matter, second strike) capability. They could launch their ICBMs at American cities or military bases, but such an attack had no chance of debilitating US second strike capacity. It would unquestionably trigger a nuclear counterattack from the US who, with their 40 missiles, would be able to utterly annihilate the Soviet Union. The only effect of a Russian nuclear attack would be to doom their own country.

[Eli’s research note: What about all the Russian planes and bombs? ICBMs aren’t the the only way of attacking the US, right?]

This means that the primary consideration in US nuclear war planning at RAND and elsewhere, was fallacious. The Soviet’s could not meaningfully destroy the US.

…the estimate contradicted and essentially invalidated the key RAND studies on SAC vulnerability since 1956. Those studies had explicitly assumed a range of uncertainty about the size of the Soviet ICBM force that might play a crucial role in combination with bomber attacks. Ever since the term “missile gap” had come into widespread use after 1957, Albert Wohlstetter had deprecated that description of his key findings. He emphasized that those were premised on the possibility of clever Soviet bomber and sub-launched attacks in combination with missiles or, earlier, even without them. He preferred the term “deterrent gap.” But there was no deterrent gap either. Never had been, never would be.

To recognize that was to face the conclusion that RAND had, in all good faith, been working obsessively and with a sense of frantic urgency on a wrong set of problems, an irrelevant pursuit in respect to national security.

This realization invalidated virtually all of RAND’s work to date. Virtually every, analysis, study, and strategy, had been useless, at best.

The reaction to the revelation

How did RAND employees respond to this reveal, that their work had been completely off base?

That is not a recognition that most humans in an institution are quick to accept. It was to take months, if not years, for RAND to accept it, if it ever did in those terms. To some degree, it’s my impression that it never recovered its former prestige or sense of mission, though both its building and its budget eventually became much larger. For some time most of my former colleagues continued their focus on the vulnerability of SAC, much the same as before, while questioning the reliability of the new estimate and its relevance to the years ahead. [Emphasis mine]

…

For years the specter of a “missile gap” had been haunting my colleagues at RAND and in the Defense Department. The revelation that this had been illusory cast a new perspective on everything. It might have occasioned a complete reassessment of our own plans for a massive buildup of strategic weapons, thus averting an otherwise inevitable and disastrous arms race. It did not; no one known to me considered that for a moment. [Emphasis mine]

According to Ellsberg, many at RAND were unable to adapt to the new reality and continued (fruitlessly) to continue with what they were doing, as if by inertia, when the thing that they needed to do (to use Eliezer’s turn of phrase) is “halt, melt, and catch fire.”

This suggests that one failure of this ecosystem, that was working in the domain of existential risk, was a failure to “say oops“: to notice a mistaken belief, concretely acknowledge that is was mistaken, and to reconstruct one’s plans and world views.

Relevance to people working on AI safety

This seems to be at least some evidence (though, only weak evidence, I think), that we should be cautious of this particular cognitive failure ourselves.

It may be worth rehearsing the motion in advance: how will you respond, when you discover that a foundational crux of your planning is actually mirage, and the world is actually different than it seems?

What if you discovered that your overall approach to making the world better was badly mistaken?

What if you received a strong argument against the orthogonality thesis?

What about a strong argument for negative utilitarianism?

I think that many of the people around me have effectively absorbed the impact of a major update at least once in their life, on a variety of issues (religion, x-risk, average vs. total utilitarianism, etc), so I’m not that worried about us. But it seems worth pointing out the importance of this error mode.

A note: Ellsberg relays later in the book that, durring the Cuban missile crisis, he perceived Kennedy as offering baffling terms to the soviets: terms that didn’t make sense in light of the actual strategic situation, but might have been sensible under the premiss of a soviet missile gap. Ellsberg wondered, at the time, if Kennedy had also failed to propagate the update regarding the actual strategic situation.

I believed it very unlikely that the Soviets would risk hitting our missiles in Turkey even if we attacked theirs in Cuba. We couldn’t understand why Kennedy thought otherwise. Why did he seem sure that the Soviets would respond to an attack on their missiles in Cuba by armed moves against Turkey or Berlin? We wondered if—after his campaigning in 1960 against a supposed “missile gap”—Kennedy had never really absorbed what the strategic balance actually was, or its implications.

I mention this because additional research suggests that this is implausible: that Kennedy and his staff were aware of the true strategic situation, and that their planning was based on that premise.
