We present a psychometric scale that assesses risk-taking in 10 evolutionary content domains: between-group competition, within-group competition, status-power, environmental exploration, food selection, food acquisition, parent-offspring conflict, kinship, mate attraction, and mate retention. We report on three studies that evaluate the scale’s validity and consistency for a sample of 1,326 participants who rated their likelihood of engagement in, the perceived riskiness of, and the benefit associated with various risky activities. Behaviors were framed as modern-day analogues of qualitatively similar actions in recurring problem domains of the ancestral environment that were potentially beneficial but also potentially costly to survival and reproductive success. As expected, respondents’ degree of risk-taking was not consistently risk-averse or risk-seeking across content domains, and a set of eight life-history variables …
