Abstract: In a review of evolutionary analysis of human behavior, Alden Smith (2000) argues that evolutionary anthropology and evolutionary psychology should not be considered competing disciplines. If evolutionary anthropology and psychology were to become more collaborative, it would aid our understanding of human nature – regardless of the different assumptions and empirical methodology used by the two disciplines. The recent 10th anniversary of “The WEIRDEST people in the world” (Henrich et al, 2010) presents a good opportunity to assess the current state of the evolutionary social sciences. While scholars (e.g., Barrett, 2020) have provided thoughts on the future direction of the evolutionary social sciences, none have explicitly evaluated the degree to which the various subdisciplines within the evolutionary social sciences have moved toward greater collaboration over the past decade. The current study uses content analysis to systematically examine if the disciplines of evolutionary anthropology and psychology are becoming more collaborative by reporting the frequency of coauthored peer-reviewed papers published in Evolution and Human Behavior (EHB), the type of data, and the empirical methodology used in these papers. A total of 737 articles published in EHB between 2009 and 2020 were coded, and no evidence of increased frequency of anthropologist and psychologist collaborations was found. While evolutionary anthropologists and psychologists did not report different types of data or topics of interest, the methods for hypothesis testing were different. I discuss limitations for the current content analysis and review suggested future steps for unification.
