Study: voice pitch indicates a mate's cheating potential

flings with individuals who have enhanced sex appeal. Because men and women have opposing interests, both have evolved subconscious strategies for reducing the potential for their partners to cheat, thus limiting the occurrence of cuckolding for men and the destruction of long term relationship investments for women.

A deep voice in males has long been correlated with enhanced sex appeal as it is a clear indicator of increased testosterone levels. However, women also believe these deep-voiced men have a higher potential to be unfaithful, and thus may not make for ideal long term mates.

Again, while men may see these high-voiced women as optimal partners to cheat with, men may be more hesitant about choosing these women as long term partners due to their increased risk of infidelity.

This intuition could also be a result of a simple logical connection. Potential mates with greater sex appeal, in this case deeper or higher voices, will be more likely to cheat simply because they will be thought attractive by more potential mates.

Voice pitch is just one of many characteristics that shapes a person's sex appeal and their potential as a short or long term mate. In terms of evolution, researches have generally agreed that the optimal mating strategy for humans is to secure one or more faithful long term partners while having a series of
