A common fmm of self-serving bias in judgment is the tendency for people to see themselves as being better than averwe in tern of socially desirable qualities, particularly those rhat are defined subjectively and that have ethical or moral mienones. A logical implication of this t e n d e m is that people should olso see themselves a s being less likely than others to exhibit such a self-sm'ng bias (Myen, 1990). This mticle describes two f m of a classrwm demonstration &signed to illustrate &s effect. In both studies, students who had k e n infmmed of the research on self-sewing hinses in judpent nevertheless saw themselves as engaging in such disronimu less ofren than the average person. Several catexo. in which tk demonstration may be ueful are rllscussed.Research has shown that, in a wide range of contexts and o n a variety of measures, people exhibit what has been termed aself-sewing bins in judgment. For example, we tend to attrihute our successes to internal causes and our failures to external forces, overestimate our likelihood of engaging in socially desirable behaviors, misrememher our hehavior in self-enhancing ways, overestimate the accuracy of our judgments, show unrealistic levels of optimism a b u t experiencing psitive events and avoiding negative events in our future, overestimate the degree to which others share our views and opinions, and underestimate the desee to which others share our skills and positive attrihutes (see Myers, 1990, for a review). Another way we exhibit this self-sewing bias is by seeing ourselves as heing better than average on many socially desirable dimensions-a phenomenon sometimes referred to as the W e Wobegon effect after Garrison Keillor's fictitious town where a11 the children are above average. Although some people necessarily are average on any given quality, not everyone can be. I once read the results of a faculty survey conducted as part of an accreditation selfstudy in which 10016 of the faculty rated their teaching performance % better than the average perjormance at the institution-This notion is illustrated more formally in a study reported by Myers (1990), based on data collected by the College Entrance Examination Board. Over 800,000 students taking the Scholactic Aptitude Test (SAT) were asked to indicate how they felt they compared to others their own age in terms of several abilities. For leadership ability, 70% rated themselves ahove average, and only 2% rated themselves below average. For the ability to get along with others, 60% rated themselves in the top lo%, and 0% rated themselves below avenge-results that may explain why nearly every student who has spoken to me a b u t a roommate conflict has reported the same difficulty (their roommare's poor skills in getting along with others).Experimental work has also demonstrated that we generally perceive our own behavior to he hirer and more moral than the behavior of others. Interestingly, however. this same work has shown similar self-enhancing perceptions to be weak or absent for the socially desirab...
