Facial cues to immunity
What is it about?
Masculine features – a strong jaw line and prominent brow – are generally thought to indicate that a man has a strong immune system. We tested this assumption in a group of Latvian men using a direct measure of immune response. The men's weight served as a better indicator of the relationship between immune response and attractiveness than masculinity did. It is therefore more likely that women use weight, rather than masculinity, in their subconscious judgements of a men's immunity.
Why is it important?
The hypothesis that masculinity serves as the predominant cue to immunocompetence in human mate choice underpins a large literature on mate choice preferences. To our knowledge, this is the first study to test the role of masculinity as a cue to immunocompetence using a direct measure of immunity. We show that adiposity is a more important cue to immunocompetence in human mate choice compared to masculinity. The findings provide new insight into the immunocompetence handicap hypothesis.
