Allport’s three mechanisms of prejudice acquisition were learning, conformity, and contact
Evidence
Allport most convincingly argued for three social mechanisms of acquisition: learning, conformity, and contact. He proposed that parents were most influential as children learned and conformed to societal rules, yet peers were most likely to provide contact in biracial schools. Although Allport touched on the more psychological processes of identity and developmental sequencing, the cognitive revolution that gave full force to such constructs was a decade away. — John F.
