B. Doosje et al., WHEN BAD ISNT ALL BAD - STRATEGIC USE OF SAMPLE INFORMATION IN GENERALIZATION AND STEREOTYPING, Journal of personality and social psychology, 69(4), 1995, pp. 642-655
The influence of the reliability and valence of sample information on
generalization to in-group and out-group target populations was invest
igated in 2 studies. In both studies the valence of the information wa
s either favorable (i.e., a positive in-group sample and a negative ou
t-group sample) or unfavorable. The reliability of sample information
was manipulated in terms of sample variability (Study 1) and sample si
ze (Study 2). In both studies the perceived central tendency of favora
ble sample information was directly generalized, but unfavorable and u
nreliable sample information was not. Moreover, generalizations based
on unfavorable and unreliable samples were characterized by enhanced v
ariability estimates for both in-group and out-group populations, ther
eby undermining unfavorable group differences. These results are discu
ssed in terms of strategic use of sample information in the formation
of social stereotypes.
