Vy. Yzerbyt et al., SOCIAL JUDGEABILITY - THE IMPACT OF META-INFORMATIONAL CUES ON THE USE OF STEREOTYPES, Journal of personality and social psychology, 66(1), 1994, pp. 48-55
According to a social judgeability analysis, a crucial determinant of
impression formation is the extent to which people feel entitled to ju
dge a target person. Two experiments tested the impact of the subjecti
ve availability of individuating information on a social judgment inde
pendent of its actual presence. In Experiment 1, people made a stereot
ypical judgement when they believed individuating information was pres
ent even if no information was in fact given. In Experiment 2, Ss who
thought they received individuating information made more extreme and
confident judgments than Ss who thought they received category informa
tion. This indicates that Ss' judgments were not simply a function of
implicit demand: The illusion of receiving individuating information l
ed Ss to believe they possessed the necessary evidence for legitimate
decision making. This result supports the existence of rules in the so
cial inference process.
