Above-average effect
the tendency of a person to hold overly favorable views of one’s own intellectual and social abilities relative to others. For example, students’ predictions of their own final exam score in a particular college class often are based on their highest score received to that point, but their predictions of someone else’s final exam score typically are based on that student’s mean score. The above-average effect appears to be common and consistent across a variety of judgment domains. Also called the better-than-average effect. Compare below-average effect.
