Y. Trope et Ep. Thompson, LOOKING FOR TRUTH IN ALL THE WRONG PLACES - ASYMMETRIC SEARCH OF INDIVIDUATING INFORMATION ABOUT STEREOTYPED GROUP MEMBERS, Journal of personality and social psychology, 73(2), 1997, pp. 229-241
Two experiments examined how category-based expectancies (CBEs) influe
nce individuating information sought when trying to make accurate judg
ments about the attitudes of targets who were members of social catego
ries that strongly or weakly implied the judged attitude. CBEs produce
d marked asymmetries in the number and content of participants' questi
ons. Specifically, participants addressed fewer questions to stereotyp
ed targets (STs) than to nonstereotyped targets (NSTs), thus acquiring
relatively little individuating information about STs prior to judgme
nt. Questions asked STs were diagnostically asymmetric--a response cou
ld better confirm than disconfirm the expected attitude, but questions
to NSTs were diagnostically symmetric--a response could equally confi
rm or disconfirm the attitude. The authors discuss asymmetric search a
s a mechanism that may protect CBEs against disconfirmation independen
t of biased processing of acquired information.
