Evolutionary psychology has demonstrated success by finding a strong correspondence between its theoretical expectations and empirical observations. This approach involves forming hypotheses based on evolutionary theory and then testing them through experimental or observational studies.

Experimental Success of Evolutionary Psychology

A key example of research in evolutionary psychology is Buss's (1989) study of mate preferences across 37 cultures. The findings generally aligned with evolutionary predictions: women tended to place a higher value on a partner's earning potential, whereas men prioritized factors indicating reproductive fitness, such as youth and attractiveness. While these trends were broadly consistent, some cultural variations were noted.

Cross-Cultural Study on Mate Preferences (Buss, 1989)

A cross-cultural study finds that both men and women consistently rank 'dependability' and 'emotional stability' as highly important traits in a long-term partner. How does this empirical finding relate to the approach of evolutionary psychology?
