J. Krueger et D. Stanke, The role of self-referent and other-referent knowledge in perceptions of group characteristics, PERS SOC PS, 27(7), 2001, pp. 878-888
Research on social projection shows that perceptions of group characteristi
cs depend, in part, on people's perceptions of themselves. According to the
principles of inductive reasoning however Knowledge of other other individ
ual group members should also predict perceptions of the group, The present
studies directly compared the use of self- and other-referent knowledge. I
n Study 1, self-judgments predicted group judgements better than judgments
about a familiar other person did. When differences in the accessibility an
d stability of self-referent and other-referent knowledge were controlled,
the predictive advantage of self-referent knowledge disappeared. In Study 2
the other person was present during assessment (i.e., visually salient) an
d other judgments predicted group judgements as well as self-judgments did.
Changes in social categorization, however; instead of increases in the ind
ividuation of the other person accounted for this finding. It is concluded
that projection is best understood as an egocentric bias rather than a form
of inductive reasoning.
