Another mechanism that could explain exaggerated ornament and the immense sexual attraction to it, could be [https://en.wikipedia.org/wiki/Handicap_principle Zahavi's handicap principle] which claims that exaggerated ornament is a costly and hence reliable signal of other desirable traits. For example a peacock with a particularly large tail can signal that even though he is easy prey (which is costly), he had good traits otherwise that enabled his survival.

For example a peacock with a particularly large tail can signal that even though he is easy prey (which is costly), he had good traits otherwise that enabled his survival. There is, however, little supporting scientific evidence. In particular, beauty is not very strongly correlated with health at all, 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> | ||
