→Autists are judged as awkward, less physically attractive and less approachable within seconds

This finding also brings into question the often-touted claim that autists fail socially primarily because they cannot read social cues and accidentally offend people. Autists do not score lower in some components of empathy, in some even higher than [[neurotypical]]s (Song 2019). | This finding also brings into question the often-touted claim that autists fail socially primarily because they cannot read social cues and accidentally offend people.

Emotional expressiveness may have evolved due to the necessity for social organization in groups of humans. Proper expression of emotion is crucial for navigating and ascending social hierarchies; hence there is a selection pressure for sexual preferences to avoid non-[[neurotypical]] individuals. | Emotional expressiveness may have evolved due to the necessity for social organization in groups of humans. Proper expression of emotion is crucial for navigating and ascending social hierarchies; hence there is a selection pressure for sexual preferences to avoid non-[[neurotypical]] individuals. The social brain hypothesis suggests that higher human behavior emerged in [[intrasexual competition|intrasexual]] and inter-group competition, making selecting individuals to outcompete others in terms of neurotypical chatter and socializing (rendering autists easy targets of such [[bullying|competition]]). Neurodivergent individuals who cannot express emotions may tend to be ineffective coalition partners. Further, atypical behavior may have served as an indicator of neurodegenerative infectious diseases in the past, often enough that humans evolved a natural aversion, a mechanism that is known as [[wikipedia:Behavioral immune system|behavioral immune system]]. | ||

An alternative or additional explanation may be sexual selection: Geoffrey Miller's [[Fisherian runaway#Behavior|''mating mind'' hypothesis]] of human intelligence suggests that higher cognition and much of human behavior may have evolved as "cognitive ornament" though [[Fisherian runaway|positive-feedback processes]] in sexual selection. Such runaway selection predicts not only an exaggerated ornament but also a highly narrowed and exaggerated preference for such ornament. This evolutionary selection pressure may suggest the struggles high-functioning autists face may, in part, be rooted in social exclusion. This exclusion seems partially based on sexually selected preferences for highly specific modes of facial and emotional expressiveness . People strongly judge based on subtle cues of physical appearance despite them being mostly unrelated to health and ability. This superficiality in judgment may be evidence of a ''few millimeters of emotional expressiveness'' and [[charisma]] in analogy to [[a few millimeters of bone]] that contribute to social and sexual exclusion. | An alternative or additional explanation may be sexual selection: Geoffrey Miller's [[Fisherian runaway#Behavior|''mating mind'' hypothesis]] of human intelligence suggests that higher cognition and much of human behavior may have evolved as "cognitive ornament" though [[Fisherian runaway|positive-feedback processes]] in sexual selection.
