Feedback loops like Fisherian runaway may have played a role in the evolution of beauty. Beauty could have evolved simply by 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. Any sort of [[sexual dimorphism]], whether behavioral or ornamental 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> | Feedback loops like Fisherian runaway may have played a role in the evolution of beauty.

Miller suggested strong positive-feedback processes in sexual selection to have given rise to higher human cognition, which he regards as too complex. Much of male courtship may consists in eliciting super stimuli in women by cognitive performance such as poetry, dancing, art and humor.<ref>https://ontherapyaspse.files.wordpress.com/2012/04/geoffrey-miller-the-mating-mind.pdf</ref> | |||
