Md. Alicke et al., PERSONAL CONTACT, INDIVIDUATION, AND THE BETTER-THAN-AVERAGE EFFECT, Journal of personality and social psychology, 68(5), 1995, pp. 804-825
Research in which people compare themselves with an average peer has c
onsistently shown that people evaluate themselves more favorably than
they evaluate others. Seven studies were conducted to demonstrate that
the magnitude of this better-than-average effect depends on the level
of abstraction in the comparison. These studies showed that people we
re less biased when they compared themselves with an individuated targ
et than when they compared themselves with a nonindividuated target, n
amely, the average college student. The better-than-average effect was
reduced more when the observer had personal contact with the comparis
on target than when no personal contact was established. Differences i
n the magnitude of the better-than-average effect could not be attribu
ted to the contemporaneous nature of the target's presentation, commun
ication from the target, perceptual vividness, implied evaluation, or
perceptions of similarity.
