Feedback loops in sexual selection like Fisherian runaway may have played a role in the evolution of beauty in some animals, but unlikely in humans as good looking individuals in primitive societies do not have higher [[reproductive success]].<ref>https://doi.org/10.1016/j.evolhumbehav.2012.01.002</ref> Beauty could have evolved simply by aesthetic sexual selection in some animals, i.e. mate selection favoring objective [[beauty]] (simplicity). But feedback loops as mentioned above may have exaggerated aspects of it, leading to increased sexual dimorphism and amplified and narrowed the attraction to specific kinds of beautiful physical traits. This also stabilizes the phenotype, making it harder to adapt to environmental changes. Any sort of [[sexual dimorphism]], whether behavioral or physical likely tends to get reinforced by such feedback loops because [[sexual dimorphism]] is inherently attractive.<ref>https://incels.wiki/w/Scientific_Blackpill#Even_chickens_prefer_sexually_dimorphic_human_faces.2C_to_the_same_extent_as_humans</ref> The narrowing in preferences may explain the [[few millimeters of bone]] effect. | Feedback loops in sexual selection like Fisherian runaway may have played a role in the evolution of beauty in some animals, but unlikely in humans as good looking individuals in primitive societies do not have higher [[reproductive success]].<ref>https://doi.org/10.1016/j.evolhumbehav.2012.01.002</ref> Beauty could have evolved simply by aesthetic sexual selection in some animals, i.e. mate selection favoring objective [[beauty]] (simplicity).

It may also explain the disproportional importance people place on good looks and why people undergo great risks and costs merely for improving their looks, e.g. by surgeries, diets or steroid intake (see [[#zyzz|Zyzz's photo]]). It could also explain the phenomenon of being ''stunned'' by someone's appearance, double takes, as well as "love at first sight" and [[oneitis]], in fact "love at first sight" is nearly entirely explained by looks.<ref>https://incels.wiki/w/Scientific_Blackpill#Love_at_first_sight_can_be_predicted_by_physical_attractiveness</ref> | It may also explain the disproportional importance people place on good looks and why people undergo great risks and costs merely for improving their looks, e.g. by surgeries, diets or steroid intake (see [[#zyzz|Zyzz's photo]]).
