The Evolution of an Idea

Abstract

This chapter considers how and why international relations might benefit from an evolutionary approach. It explains the evolutionary biology's long history of misunderstanding and resistance in the social sciences since the “sociobiology” debate of the 1970s. It also reviews how the natural and social sciences have both moved on since the 1970s, including the promise for a future of mutual collaboration on strategic instincts. The chapter focuses on evolutionary biology to understand the origins and functions of cognitive biases and comprehend the selective pressures that shaped the brain in the first place. It addresses the question of whether psychological phenomena originate from nature or nurture.
