Fisherian runaway: Difference between revisions

The sexy son hypotheses was also proposed by Fisher and is merely a [https://en.wikipedia.org/wiki/Corollary corollary] of Fisherian runaway regarding men's beauty. It simply states that the positive feedback loop makes men's beauty so attractive that women are willing to choose a beautiful male regardless of other considerations such as morality, ability to provide, physical or mental health etc. because the males' beauty—which is partly heritable—confers on their offspring a potential reproductive advantage. There is indeed [[Scientific_Blackpill#Women_are_less_likely_to_use_a_condom_with_a_more_attractive_male_partner|compelling evidence]] of this behavior. Of course men also more readily copulate with beautiful women, but men have less [[Bateman's principle|parental investment]] and hence do not need to care as much about such considerations. Further, women's ability to provide does not matter nearly as much as men's and women also largely lack this ability (at least they did before the invention of modern welfare states). Hence, women's behavior of disregarding the ability to provide merely at the benefit of better looking offspring has much more drastic implications.

The male equivalent is raping a sexy woman (to produce a sexy daughter). Both are risky strategies. Engaging in [[alpha fuxx, beta buxx]], the woman risks not being provided for. Engaging in rape, the man risks death and exile. But provided some do engage in these strategies, better looking offspring apparently can make up for these risks on average (in terms of evolutionary fitness). Only feedback loops in sexual selection can explain this.
