The sexy son hypothesis in evolutionary biology and sexual selection—proposed by Ronald Fisher in 1930—states that a female's ideal mate choice among potential mates is one whose genes will produce male offspring with the best chance of [[reproductive success]].
The ''sexy son hypotheses'' was also proposed by Fisher and considers runaway sexual selection of men's [[looks]] and sexiness. It simply states that the positive feedback loop can make women so attracted to male ornament that women will choose a very good looking male regardless of other considerations such as morality or paternal investment, because the male's ornament—which is partly heritable—confers on their offspring a potential reproductive advantage.<ref>https://academic.oup.com/beheco/article/19/2/456/214088</ref> This is particularly staggering in women, otherwise [[libido|coy]], engaging in casual sex with men way above their league (i.e. getting [[pump and dump|pumped and dumped]]).
This implies that the male's ability to provide is less important, especially in polygynous species (like humans are, moderately) where the lesser paternal investment must be outweighed by the benefit in reproductive success the female achieves through mating with an attractive male. She forgoes direct benefits (resources and protection) in exchange for indirect genetic benefits (greater reproductive success). Though these are not necessarily mutually exclusive, of course.<ref>https://academic.oup.com/beheco/article/19/2/456/214088</ref>
 
Since women heavily depended on men's provision, only a [[Chad|tiny percentage]] of men is good looking enough that they can skip women's typical coy waiting time (around 4%, compared to 60-70% for men).<ref>https://incels.wiki/w/Scientific_Blackpill#Men_like_61.9.25_of_female_profiles.2C_women_like_only_4.5.25_of_male_profiles</ref>
Women would also much more readily forego using a condom with a good looking mate.<ref>https://incels.wiki/w/Scientific_Blackpill#Women_are_less_likely_to_use_a_condom_with_a_more_attractive_male_partner</ref> Of course, men also more readily copulate with sexy women, but men have less [[Bateman's principle|parental investment]] and hence do not need to care as much about such considerations (as evidenced by men's much higher inclination to copulate with a random stranger, i.e. lower standards for casual sex; men are also more choosy when they actually have to provide).
Hence, for women, copulating only based on sexiness has more drastic implications, hence people care less about the "sexy daughters" phenomenon. However, arguably, a similarly risky strategy for men is raping a sexy woman (to produce sexy daughters as a promising vehicle of one's own genes). Both are irresponsible and socially parasitic as they depend on others providing on the offspring (in modern societies via taxes). Engaging in [[alpha fuxx, beta buxx]], the woman risks not being provided for. Engaging in rape, the man risks death and exile and also won't provide for the offspring. But provided some do engage in these strategies, may mean such sexual strategies have evolved because better looking offspring can make up for these risks on average (in terms of evolutionary fitness).

Since having sexy sons stems from women choosing the mate they are most physically attracted too, the male equivalent is doing the same thing (resulting in sexy daughters). However, men are typically [[bateman's principle|less choosy]] in regards to their standard in female looks (at least for relationships that require less investment). Males choosing women whom they were most physically attracted too, and could attain, having been the norm throughout human history, has resulted in the development of female ornamental traits designed to attract men.
