Feedback loops in sexual selection like Fisherian runaway may have played a role in the evolution of beauty. Beauty could have evolved simply by aesthetic sexual selection, 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.

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. | ||
While it is not proven that feedback loops were involved in shaping human ornament, or just sexual selection without feedback, it is certainly plausible, especially considering the importance people place on good looks. It could explain 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, as well as "love on first sight" and [[oneitis]]. | While it is not proven that feedback loops were involved in shaping human ornament, or just sexual selection without feedback, it is certainly plausible, especially considering the importance people place on good looks.
