Rose McDermott (Brown University): “the Influence of Psychological Factors in the Search for Strategic Stability”

“The Influence of Psychological Factors in the Search for Strategic Stability.”

Nuclear deterrence and strategic stability have always rested on fundamental assumptions about the nature of human psychology that are dubious at best and demonstrably empirically false at worst. Rationality, for example, represents one of these beliefs that have little, or at least restricted, basis in reality. And yet the entire fate of the planet depends, in essence, on our collective delusion that pivotal actors, no matter how selfish, remain fundamentally rational and intent on preserving survival if nothing else. Like most judgmental biases, this perception may be mostly accurate most of the time. However, it suffers from systematic and predictable flaws that can occur in predictable ways that can undermine not only our notions of rationality but also the foundations of stability and deterrence.

There are many judgmental biases that could potentially affect decision making in general, with profound implications for nuclear decision making in particular. However, after providing a brief discussion of decision processing in general, this paper will concentrate on five of the most notable candidates for improving our understanding of the way human psychological architecture may not be well suited for understanding the enormous destructive potential of weapons in the nuclear age, and thus could hinder effective decision making in the realm. These include overconfidence, the planning fallacy, the illusion of validity, psychic numbing and the prominence effect. Alone, and in concert, each of these common processes can influence how leaders and others make judgments and reach decisions without recognizing the bias inherent in their choices. A brief comment on how evolutionary perspectives which typically argue against the notion of error actually support wider concerns in this particular arena precedes a discussion about the policy implications suggested by these insights.
