Abstract

The ratio of men to women in a given ecology can have profound influences on a range of interpersonal processes, from marriage and divorce rates to risk-taking and violent crime. Here, we organize such processes into two categories - intersexual choice and intrasexual competition - representing focal effects of imbalanced sex ratios.

Keywords: cognition; competition; evolution; psychology; relationships; sexuality.
