Sex differences and life style-dependent shifts in the attunement of self-esteem to self-perceived mate value: Hints to an adaptive mechanism?

It has been suggested that self-esteem is reactive to signs of social rejection, and that this ``sociometer'' mechanism becomes attuned to those personal attributes that affect social acceptance by significant others. Based on evolutionary models of human mating, we predicted that self-esteem should be more attuned to self-perceived mate value in men (when compared to women) who pursue short-term mating tactics, especially if they are unsuccessful therein. In a web-based study (N=2670), we found that mate value self-perceptions had a stronger effect on self-esteem on those who had less short-term mating success in the past. However, being in a committed relationship or parenthood reduced the impact of mate value self-perceptions. As expected, these effects were specific to men. These results are suggestive of a psychological mechanism based on adaptive sociometer attunements that could help men to choose their optimal mating tactic and might thus partly explain intrasexual differences in sociosexuality.
