Deterrence theories purport to supply the auxiliary assumptions rational choice theories need to predict rational strategic behavior. They generally assume that would-be initiators are (i) instrumentally rational; (2) risk-prone gain-maximizers; (3) free of domestic constraints; and (4) able to identify themselves correctly as defenders or challengers. These assumptions are contradicted by empirical studies that indicate that risk-prone, gain-maximizing initiators are relatively uncommon; that leaders at times calculate as deterrence theories expect, but behave contrary to their predictions; and that the calculus of initiators generally depends on factors other than those identified by deterrence theories. Deductive theories of deterrence are also inadequate because they do not define their scope conditions. Nor can they accommodate deviation by initiators from processes of rational calculation. Rational deterrence theories are poorly specified theories about nonexistent decision makers operating in nonexistent environments.

3 Formal concepts of risk and uncertainty apply to the estimation of the likelihoods of given alternatives. In a “risky” choice, the probability distribution of a consequence is known, even though its occurrence is not. In an uncertain environment, by contrast, even this distribution of probabilities is unknown and no a priori estimates can be made. The formal distinction between risk and uncertainty does not capture the attributes of the environment of strategic decision making. Once leaders estimate the probability of a consequence of an option, even without adequate baseline information on which to make their judgments, they make their choice under conditions of risk.
4 In models of subjective expected utility, preferences under conditions of risk are determined by at least two separate factors: the strength of the preference for the consequences under certainty, and the attitude toward risk.

17 In reviewing the predictive use of subjective expected utility models, Schoemaker (fn. 4, 538–39) argues that evidence counter to the theory can often be refuted because it is indirect. The most irrefutable evidence, which directly concerns the axioms, is discounted in the positivist tradition. Ex post facto interpretation of a decision as rational through the addition of factors not specified by the model treats the optimality of behavior as an essentially unfalsifi-able metapostulate. Consequently, ex post empirical models have limited refutation power regarding the corresponding theoretical ex ante model.
18 Mefford (fn. 7) argues persuasively: “Interpreting the uninterpreted key concepts of rational choice requires spelling out for each actor that actor's utility function, perceptions of uncertainty, and perceived set of outcomes. Because there is virtually no limit on the variety of ways that these concepts of rational choice can be mapped onto a political world, rational-choice based models of deterrence seem to suffer from much the same open-ended character ... of the case-based work. ... The number of auxiliary propositions that can be attached to the uninterpreted core of rational choice is disturbingly large. It matters which ones are chosen. And, the rational choice theorist's choice of auxiliary propositions is a legitimate target for critical examination” (emphasis in original), p. 9.

26 As Mefford argues (fn. 7), what is at issue is the correspondence between the essential terms in the core of rational models and the auxiliary assumptions of deterrence theory (pp. 7–10). These auxiliary assumptions are the costs of war, the probability of winning, and the probability of retaliation. Achen and Snidal ignore the necessity to test these propositions as the core of an empirical theory of deterrence.

29 Technically, Zagare's analysis is based on a different interpretation of the meaning of two-by-two games. The numbers denote rates of payoff rather than single payoffs, with players moving around within the matrix.
30 O'Neill, Barry, “Game Theory and the Study of the Deterrence of War,” in Stern, Paul C. et al., eds., Perspectives on Deterrence (New York:Oxford University Press, 1989Google Scholar). O'Neill notes: “Previous concepts had tried to draw a sharp line between rational and irrational actions based solely on the utilities of the outcomes, but recent approaches regard rational actions as interlocked with rational beliefs. ... Whether they [the players] adopt these beliefs is an empirical question, and thus the validity of an equilibrium becomes a question of social science rather than mathematical axioms. Models like this seem more realistic and reduce the isolation of game theory applications from other social sciences.”

33 The Egyptian Minister of War, Shams al-Din Badran, estimated in May 1967 that Egyptian forces could handle military intervention on behalf of Israel by the Sixth Fleet; cited by Riad, Mahmoud, The Struggle for Peace in the Middle East (London:Quartet Books, 1981), 23Google Scholar. Is this, in Snidal and Achen's terms, psychopathological reasoning that falls outside the scope of a “rational theory of deterrence,” or evidence of systematic miscalculation that defeats the expectations of rational deterrence theory?
