In almost as quickly as it takes to blink an eye, we make assumptions about a group of people. New research from UCLA (University of California, Los Angeles) shows people perceive the sex ratio of a group, and decide if the group is threatening or not, in half a second. The perceptions of the number of men in the group are accurate, according to the research.
Nicholas Alt (UCLA), Brianna Mae Goodale (UCLA), David J Lick (New York University) and Kerri Johnson (UCLA) conducted the research. The results appear in the journal Social Psychological and Personality Science.
