Height discrimination (also known as heightism) is prejudice or discrimination against individuals based on height. In principle, it refers to the discriminatory treatment against individuals whose height is not within the normal acceptable range of height in a population. Various studies have shown it to be a cause of bullying, commonly manifested as unconscious microaggressions. Modern Western height discrimination originated in 19th century eugenic, Social Darwinist, and white supremacist movements, beginning with eugenicist Sir Francis Galton's observation of the correlation of human height between parents and offspring. These movements promulgated pseudoscientific beliefs about the superiority of larger male stature, most grotesquely embodied by the Nazi height ideals within the social construct of the Aryan master race.
Research indicates that people often use height as heuristic proxy to judge social status and fitness, regardless of its accuracy. In related studies, men have been found to be more strongly judged based on height than women.
