Chronotype dependent choosiness and mate choice

Chronotype influences the success of mate choice. Evening types reproducibly report higher mating success than morning types. In this study, we directly assessed the reasons for these advantages, hypothesizing the degree of choosiness a person has concerning mate choice being causal. A total of N = 1247 (male = 440/female = 807) heterosexuals participated in an experiment. We defined two facets of choosiness: attractiveness rating and dating desire. Participants rated the attractiveness of opposite sex stimuli and indicated whether they had a desire to date the stimuli or not. Morningness in males correlated with a higher attractiveness-rating and dating desire, while results of evening-orientated males, and females in general were not significant. The causes of higher mating success in eveningness remains unclear. Unexpectedly, we showed that eveningness is related to a higher choosiness.

Automated summary

The study found that morningness in males is correlated with higher attractiveness-rating and dating desire, while the results for evening-orientated males and females in general were not significant. Evening types may be more choosy in mate selection, which could be a reason for their higher mating success.
