abstract
- A common method for assessing blatant dehumanization asks participants to rate "how evolved" they think members of various social groups are using the Ascent of Human scale (AOH) that transitions in stages from a crawling ape to a fully upright modern human. However, little is known about how task instructions affect participant ratings. In this pre-registered study, participants saw alternative forms of instruction including the traditional instructions emphasizing "evolution", a prompt without any reference to evolution, and a prompt that clearly explained that the scale assesses dehumanization. Instruction type had no effect on dehumanization ratings on the AOH scale. These results support the idea that the AOH scale is a robust means of assessing blatant dehumanization.
