Also called the ''good genes hypothesis'', this claims the exaggerated ornament is a costly and hence a reliable signal of other desirable traits. For example, a peacock with a very large tail would be easy prey (which is costly), and thus would most likely have other good traits that make up for this handicap (good genes). There is, however, little supporting scientific evidence. In humans in particular, beauty is not strongly correlated with health at all (those it is weakly), and even less with cognitive ability.<ref>https://incels.wiki/w/Scientific_Blackpill#Attractive_people_are_perceived_much_more_positively_than_they_really_are</ref> | Also called the ''good genes hypothesis'', this claims the exaggerated ornament is a costly and hence a reliable signal of other desirable traits.
