•Openness to Experience shifted as a function of mating opportunity.•Openness decreased in response to potential mates of average attractiveness.•This differed from Openness-shifts in response to attractive potential mates.•Mating strategy, attractiveness, and sex interacted to predict these shifts.
The current study tested the hypotheses that (1) psychological adaptations calibrate Openness to Experience to facilitate or deter pursuit of short-term mating, and (2) this calibration varies as a function of mating strategy, physical attractiveness, and sex—individual differences that shift the costs and benefits of alternative personality strategies. Participants completed a personality inventory before and after reading vignettes describing mating opportunities of different durations (short- and long-term) with individuals of differing levels of attractiveness. Among study findings, participants presented with short-term mating opportunities with individuals of average attractiveness exhibited down-regulated Openness relative to those presented with highly attractive mates. Moreover, these effects varied as a function of the interaction between participants’ sex, mating strategy, and attractiveness. These findings are consistent with the hypothesis that evolved psychological mechanisms adaptively calibrate Openness levels in response to short-term mating opportunities. More broadly, they highlight the heuristic value of an evolutionary framework for the study of personality and individual differences.
