Ja. Shepperd et al., CONSTRAINTS ON EXCUSE MAKING - THE DETERRING EFFECTS OF SHYNESS AND ANTICIPATED RETEST, Personality & social psychology bulletin, 21(10), 1995, pp. 1061-1072
Although prior research has documented a pervasive egocentric bias in
the self-perceptions, self-ascriptions, and behaviors of most people,
shy individuals seem not to share this bias. This study examined wheth
er the apparent absence of an egocentric bias among shy individuals is
reflected in their excuse making following poor performance. It also
examined whether anticipating a challenge to one's excuses would dissu
ade even nonshy individuals from making excuses. Shy and nonshy subjec
ts received either success or failure feedback on an intelligence test
and then were or were not told that they would be retested. Consisten
t with predictions, shy individuals refrained from making consistency-
lowering excuses regardless of performance feedback and retest instruc
tions. By contrast, nonshy subjects made consistency-lowering excuses
after failure feedback, but only when they expected that their excuses
would go unchallenged by a retest.
