INTRODUCTION

English translation pending.

CORE DEFINITION

Proposed by Gordon Allport in The Nature of Prejudice. The hypothesis holds that prejudice between groups can be reduced by direct contact, but only under four conditions: equal status between the groups, shared goals, cooperative interdependence rather than competition, and support from authorities or institutions. Mere contact without those conditions can increase hostility rather than reduce it, which is why the qualifying conditions carry as much weight as the claim itself.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Design the encounter: engineer equal status and a shared goal before bringing groups together - Check the conditions: verify that all four are present, since missing one can worsen hostility - Replace symbolism: create interdependent tasks rather than symbolic gestures of diversity

Prejudice rests partly on abstract category labels that leave individual variation invisible. Personal interaction under equal status supplies individuating information, which competes with the stereotype and, repeated often enough, displaces it. Shared goals make the other group's success instrumental to your own, which converts the relationship from zero-sum into cooperative and makes empathy possible.
