An experiment employing a sample (N=280) of undergraduates from an urb
an university was designed to test the general hypothesis that the per
ception of justice and injustice in life events depends upon the relat
ionship between two variables that are part of the stimulus situation:
the valence of the person being observed (good or bad), and the valen
ce of the outcome experienced by that person (positive or negative). T
he findings from both qualitative (analysis of spontaneous comments) a
nd quantitative scale ratings supported the prediction that justice an
d injustice perceptions depend respectively on whether the signs of th
e person-outcome valences are the same or different. Two perceptual bi
ases were revealed by the analysis. The first was a positive outcome b
ias: respondents rated as more just outcomes that were positive regard
less of the goodness or badness of the person in the life event. The s
econd was a justice bias: respondents in both measures found the just
life events to be more just than unjust life events to be unjust. Fina
lly the more religious respondents perceived the life events as more j
ust regardless of the patterns of person-outcome valences than did the
less religious, suggesting a third, religiosity bias. A number of the
oretical implications and questions for future research were discussed
, including the quantification of the hypothesis and its cross-cultura
l generality.
