Gender differences in risk behaviors can be explained by evolutionary theory, which predicts differences in the domain under analysis. In order to investigate this question, we used a risk propensity scale with 358 people, who answered a questionnaire of 15 items covering five domains, evaluated concerning the dimensions Perception, Attractiveness and Probability of engagement. In general, gender differences were found in the dimensions, but the analysis of the domains suggested differences only in Environmental challenge, and Mating and resources. These results are consistent with the literature about the greater propensity of men to risk, but also suggest that the domain involved may be relevant in risk propensity. The need for further research to refine the present findings is discussed.
