DescriptionThis research tests a new model of the role of stereotypes and individuating information. The Stereotyping and Individuation Process Model (SIP) predicts that individuals will use stereotypes versus individuating information based on relevance to the judgment. Three steps of the model were tested by examining discrimination against Arabs and Muslims in an airport security setting. A 2 (Target Ethnicity) x 3 (Target Religion) x 2 (Participant Ethnicity) Mixed Model was employed where Target Ethnicity and Target Religion are within-subjects factors. Participants were asked to review 36 passengers in an airport and recommend suspicious passengers for further questioning. Results show preliminary support for Steps 1 through 3 of the model. Anti-Arab and Anti-Muslim prejudice predicted recommendation for questioning. Additionally, a Black Sheep Effect was found where White Muslims were discriminated against more than any other group. An In-Group Bias effect was found where White participants favored White targets and Non-White participants favored Arab targets.
