This brief self-report measure assesses beliefs about whether social groups have an inherent, underlying “essence” that is stable over time. The Psychological Essentialism Scale is used to characterize the degree to which respondents view group membership as natural, immutable, and potentially biologically grounded. It was developed by Susan A. Gelman and Lawrence J. Hirschfeld.
The instrument contains 7 items and typically takes about 2 minutes to complete. Scores from the Psychological Essentialism Scale are commonly interpreted as an index of essentialist thinking about social categories and may be used in research or applied settings focused on intergroup attitudes and related sociocognitive beliefs.
