This is Study 2 reported in a paper by Abrams, Travaglino et al. on the Deviant Ingroup Protection Effect, in the Journal of Personality and Social Psychology. Methods complied with APA ethical standards and were approved by the University of Kent's Psychology ethics board (ID 2011855) The data are in an SPSS .sav file called DIP_Study2_Tax Design Participants viewed and evaluated either six In-Category or six Out-Category groups.

Participants One-hundred-and-sixty-five US residents were recruited from the crowdsourcing platform Academic Prolific.

There were 80 participants in the in-category valid condition and 85 in the out-category condition.
