McElreath and Boyd's textbook (Chapter 8.2) presents a model of runaway selection based on Lande's classic paper: Lande, R. (1981). Models of speciation by sexual selection on polygenic traits. Proceedings of the National Academy of Sciences, USA, 78:3721–3725.
They also demonstrate that "sexy sons" and "good genes" are not different explanations, but parts of a continuum, based on: Kokko, H., et. al. (2002). The sexual selection continuum. Proc B, 269:1331–1340.
Isn’t this Fisherian runaway/ runaway selection? I suspect it’s the leading cause behind the sexless male epidemic (incels). Women’s emancipation has given them access to the best males, they’re unlikely to settle for less as they did in previous generations.pic.twitter.com/aSOrBO8w6t
Mmm it could be, maybe also, is the reason why some atractive women have sons and daughters with stupid, frecuently unemployed mens that didn't went to college or don't have what it takes to have a college degree, BUT, are, to the eyes of women, "atractive" mens.
