I'm reading Alan Wolfe's The Future of Liberalism (2009). On p. 45, Wolfe refers in passing to "some scholars [who] have relied on sociobiological arguments to develop theories of international relations supportive of neoconservative understandings of how the world works." Curious about which scholar(s) Wolfe had in mind (I guessed Bradley Thayer, author of a book on Darwinism and IR), I turned to his endnotes. My guess was wrong. The single work Wolfe cites in this connection is Stephen P. Rosen's War and Human Nature (2005).
It happens that I'd read Rosen's book, but it was a while ago and I didn't remember it especially well, so I took it down from the shelf. "Relie[s] on sociobiological arguments to develop theories of international relations supportive of neoconservative understandings of how the world works" is not, I think, a particularly good description of much of what Rosen is trying to do. In his chapter 2, for example, "Emotions, Memory, and Decision Making," Rosen draws on animal and human research to argue for the importance of "emotion-based pattern recognition" in decision-making. Pattern recognition happens when the brain processes information "in blocks or chunks" (p.34), and "pattern recognition of events associated with past emotional arousal radically reduce[s] decision-making time" (p.35). With respect to foreign policy decision-making, Rosen hypothesizes, among other things, that "if decisions are made on the basis of emotion-driven pattern recognition, the decision will be made quickly and early in the process, despite the complexity of the situation and the availability of contradictory analysis and data" (p.55). He then examines several historical cases where this kind of decision making (arguably) occurred.
The argument may or may not be persuasive, but at least this chapter of War and Human Nature would appear to have little to do with "neoconservative understandings of how the world works." Indeed one might well be able to apply 'emotion-based pattern recognition' to the Bush administration's decision to invade Iraq. I doubt that the results would be pleasing to neoconservatives.
