===Good genes===
Good genes hypothesis or ''Zahavi's handicap principle'' claims 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 and ornament is not strongly correlated with health at all (only weakly), and even less with cognitive ability, though people strongly perceive them to be.<ref>https://incels.wiki/w/Scientific_Blackpill#Attractive_people_are_perceived_much_more_positively_than_they_really_are</ref>
A computer model created by Chandler et al., found evidence that traits initially spread by runaway selection can also become indicator traits of "good genes".  They also found that these ornamental traits could serve as indicators of "good genes" even when they didn't function as costly signals, contradicting Zahavi's handicap principle. They concluded that runaway selection for ornamental traits and selection for indicator (honest signal) traits should therefore be viewed as complementary mechanisms that serve to reinforce each other.<ref>https://app.dimensions.ai/details/publication/pub.1009220931</ref>

Topics related to sexual selection are subject to political controversy, especially since female scientists are involved (or their [[white knight|white knights]]) and they do not want to portrait female choice or behavior as maladaptive.

Further, considering women's secondary sexual characteristics as means to conspicuously advertise themselves implies that they signal nubility, which however occurs long before reaching legal age.
