Da. Wilder et al., ENHANCING THE IMPACT OF COUNTERSTEREOTYPIC INFORMATION - DISPOSITIONAL ATTRIBUTIONS FOR DEVIANCE, Journal of personality and social psychology, 71(2), 1996, pp. 276-287
Counterstereotypic behavior by a single our-group member often fails t
o change out-group stereotypes because it can be dismissed as an excep
tion to the rule. The impact of the ''exception'' fan be strengthened
by making the exception appear to be a typical out-group member and by
encouraging a dispositional attribution for the exception's counterst
ereotypic behavior. These hypotheses were supported in 3 experiments u
sing both artificial and real social categories and both positive and
negative stereotypes. When counterstereotypic behavior by a typical me
mber of the out-group was attributed to a stable internal cause, it wa
s effective in moderating out-group stereotypes. However, the same beh
avior had virtually no impact when it was either performed by an atypi
cal group member or attributed to external causes or to unstable inter
nal causes.
