The extra credit effect in interpersonal attraction

Abstract An experiment was conducted in which three levels of personal evaluation (positive, mixed, or negative) were crossed with two levels of dependence of the evaluator (high or low) and two levels of accuracy of the evaluation (high or low). Liking for the evaluator was expected to increase linearly with the favorableness of the evaluation, with two possible exceptions: When a positive evaluation from a dependent evaluator was inaccurate, and when a negative evaluation from a dependent evaluator was accurate. In the former case, the obvious inaccuracy of the positive evaluation in the face of the temptation to ingratiate was expected to elicit a decrement in liking (an “ingratiation effect”) by the person being evaluated. In the latter case, the honesty of the evaluator in the face of the temptation to ingratiate was expected to elicit an increment of linking (an “extra credit effect”) by the person being evaluated. Only the second of these two possibilities was supported.
