In three studies, we tested the hypothesis that the belief in a just and an
unjust world are distinct constructs. The two-factor model was supported t
hrough the use of structural equation modeling and the pattern of correlati
ons with religiosity, well-being, and political ideology. Specifically, onl
y the belief in a just world correlated positively with religiosity, three
indicators of well being (life satisfaction, mood level, and affect), and p
referring a well-established political party. A comparison between prisoner
s and guards revealed further differences. Prisoners endorsed more strongly
the belief in an unjust world, but both guards and prisoners equally endor
sed the belief in a just world, We discuss the differences between the beli
ef in a just and an unjust world, and the implications of believing in an u
njust world for social behavior. (C) 2001 Elsevier Science Ltd. All rights
