A Rational Approach to Stereotype Change

Existing theories of stereotype change have often made use of 
categorisation principles in order to provide qualitative explanations 
for both the revision and maintenance of stereotypical 
beliefs. The present paper examines the quantitative methods 
underlying these explanations, contrasting both rational and 
heuristic models of stereotype change using participant data 
and model fits. In a comparison of three models each simulating 
existing descriptions of stereotype change, both empirical 
data and model fits suggest that stereotypes are updated using 
rational categorisation processes. This presents stereotype use 
as a more rational behaviour than may commonly be assumed, 
and provides new avenues of encouraging stereotype change 
according to rational principles.
