P. Borkenau et A. Liebler, CONVERGENCE OF STRANGER RATINGS OF PERSONALITY AND INTELLIGENCE WITH SELF-RATINGS, PARTNER RATINGS, AND MEASURED INTELLIGENCE, Journal of personality and social psychology, 65(3), 1993, pp. 546-553
Several studies have shown above-chance agreement of self-reports on e
xtraversion and conscientiousness with ratings by strangers, indicatin
g that ratings by strangers might be quite accurate. Because self-repo
rts are a less-than-ideal criterion to evaluate the accuracy of strang
er ratings, however, the present study compared them also with ratings
by acquaintances and with targets' performance on an intelligence tes
t. Ratings of extraversion, conscientiousness, and intelligence by str
angers having been exposed to a videotape of targets were significantl
y related to self-reports of these traits as well as to ratings by acq
uaintances. Moreover, ratings of intelligence by strangers were relate
d to targets, measured intelligence, provided that judges had been exp
osed to a sound film of the targets.
