Abstract
People possess a pre-conscious need to believe in the existence of justice in the world. This belief in a just world (BJW) is usually measured with self-report scales. Dalbert et al., Psychologische Beitrage, 29(4), 596–615 (1987) and Dalbert, Social Justice Research, 12(2), 79–98 (1999) have developed the general belief in a just world (GBJW) and personal belief in a just world (PBJW) scales as psychometrically robust measures of just-world beliefs. We conducted three studies to demonstrate the validity of the Persian versions of belief in a just world scales and the importance of distinguishing between GBJW and PBJW. First, we confirmed the factor structure. reliability, convergent validity (self-esteem, life satisfaction, and religiosity), and divergent validity (big five personality factors and dark triad traits) of GBJW and PBJW using Iranian participants (N1 = 454). Second, the associations of GBJW and PBJW with perceived threat of unjust behavior directed to self or others were assessed using two scenario based studies (N2 = 279, N3 = 292) in the context of kin favoritism. Our finding showed that both GBJW and PBJW negatively predict perceived likelihood of kin favoritism. However, GBJW was a stronger predictor when injustice was directed at others, and PBJW was a stronger predictor when injustice was directed at self. Consistent with previous research and theoretical assumptions, perceived likelihood of punishment mediated these associations.

Kin Favoritism Scenarios
-
1.
You are a PhD student in one of Iran’s prestigious universities. Your supervisor has been given an opportunity to choose a student to study abroad as a visiting scholar for 6 months. He/she must choose among you and other students under his/her supervision. You are the one with the best GPA and resume but one of the other students is a relative of your supervisor. The supervisor clearly knows that any kind of discrimination is against the university’s rules and regulations.

2.
You are a film director and the movie you have recently made is going to be reviewed in an influential film magazine. This week, another movie with a much lower quality is going to be evaluated beside yours, and one of the movies will be chosen and featured as the “best movie of the week”. Various critics work under the supervision of the chief editor of the magazine. Coincidentally, the critic who is in charge of this week’s review process is a relative of the other movie’s director. This critic clearly knows that discrimination and choosing a movie based on anything other than cinematic standards is against the magazine’s rules and regulations.

3.
You have taken your lawsuit to a local court. After reviewing the case carefully, your lawyer has assured you that you have the upper hand, and the judge will give a verdict in your favor. Coincidentally, the judge that is assigned to your case is a relative of the other party. All the judges in the courthouse work under the supervision of the Department of Justice. The judge clearly knows that discrimination and giving a verdict based on anything other than the case material is against the law.

4.
You have been chosen as one of the two final candidates for a government job position. Considering the resumes, you are clearly better qualified for the job than the other candidate. A recruiter who works under the supervision of higher ranks has to do an interview with you and the other candidate to decide who gets the job. Coincidentally, the recruiter turned out to be a relative of the other candidate. This recruiter knows that discriminating between candidates and not choosing the most qualified person is against the rules.
-
5.
You have had a car accident in a secluded area of the city and both cars have had minimal damage. The other driver is clearly to blame for this accident. A police officer arrives and investigates the scene of the accident. Coincidentally, the officer called for this accident is a relative of the other driver. This police officer clearly knows discrimination for any reason is against the law.
