判定の一貫性と利己的バイアスが当事者による判定に対する公正知覚と判定者に対する知覚に及ぼす影響 The effects of consistent judgments and egocentric bias on the perceived fairness of the judgment by the person concerned and the perception of the judge by the person concerned

It has generally been expected that inconsistent judgments would have a negative influence on their perceived fairness, and that egocentric bias would force perceivers to make a more positive response to favorable outcomes than to unfavorable ones. In consequence, perceivers with favorable outcomes derived from inconsistent judgments would impair the perceived fairness less than perceivers with unfavorable outcomes. Thus, we can anticipate that this interaction would also be observed in the case of perception of the judge, for the perceived fairness can be considered to correlate with perception of the judge. We had under graduate students (N=270) participating in this study. The results of Analysis 1 supported the effect of consistent judgments, though it did not show the effect of egocentric bias and the interaction we had expected so far. However, the result of Analysis 2, employing a stratified correlation analysis, revealed that egocentric bias could be observed in the perceivers with unfavorable outcomes derived from inconsistent judgments. These findings suggest that framing could be a factor in the appearance of egocentric bias.
