It is expected in existing theories that bias suppression, known to be a procedural justice norm (Leventhal, 1980), has a positive influence on perceived fairness and that egocentric bias causes perceivers to make a positive response to favorable outcomes more than to unfavorable ones. In addition, we tend to exhibit egocentric bias when unfavorable outcomes emerge; an interaction between the favorability of an outcome and egocentric bias is therefore to be expected. That is, perceived fairness would be lower in unfavorable outcome without bias suppression than in others. For the sake of meeting expectations, we have availed ourselves of modified scenarios from Study 1 of De Cremer (2004). Sixty undergraduate students participated in this study, of whom 55 were analyzed. Almost all of the results are to meet expectations. It can be considered that procedural justice might be superior to egocentric bias in perceived fairness; however, the influence of egocentric bias should not be disregarded.
