Just-World Hypothesis

Lerner's experiment and theory

Lerner and Simmons (1966) showed female participants a scene in which another woman appeared to receive electric shocks whenever she made mistakes on a learning task. The victim was a confederate who received no real shocks. When participants had no way to stop her suffering, they tended to rate the victim more negatively. When they could help her, this derogation decreased. In The Belief in a Just World: A Fundamental Delusion, Lerner (1980) explained that, to protect their belief that the world is just, people who witness undeserved suffering either help the victim or, if they cannot, reinterpret the victim as having deserved it. Lerner and Miller (1978) laid out how this process connects to attribution theory. The tendency also dovetails with the fundamental attribution error, the tendency to attribute outcomes to personal dispositions rather than situations.

Measurement and theoretical development

Rubin and Peplau (1975) developed a scale to measure belief in a just world as an individual difference, reporting that people with a stronger belief tend to be more authoritarian and less sympathetic toward the poor and victims. Furnham (2003) reviewed the decade of research that followed. Dalbert (1999) distinguished a personal belief that the world is just to me from a general belief that the world is just in general. Research confirmed that the personal belief is more closely tied to subjective well-being, while the general belief is more closely tied to harsh social attitudes. Bègue and Bastounis (2003) supported this two-dimensional model with data from several countries. Using a modified Stroop task, Hafer (2000) showed that stories of innocent victims heighten attention to justice-related words, providing evidence that the belief is genuinely threatened. Hafer and Bègue (2005) synthesized the experimental research, laying out methodological problems and future challenges.

Social consequences and redistributive politics

Belief in a just world can have the social consequence of justifying inequality. Jost and Banaji's (1994) system justification theory held that people are motivated to see the existing social system as legitimate, and that even disadvantaged groups can internalize such beliefs. Economists have also used the concept. Alesina and Angeletos (2005) showed that different equilibria can arise: societies that believe effort determines success choose low taxes and little redistribution, while those that believe luck matters choose more redistribution. Bénabou and Tirole (2006) argued that people maintain a belief in a just world for motivational reasons, and that this can explain differences in redistributive policy between the United States and Europe. The just-world hypothesis thus stretches from individual psychology to social policy. It is also discussed alongside research on relative deprivation, the sense of deprivation that comes from comparing oneself with others.

FAQ

What is the just-world hypothesis in simple terms?

It is the wish to believe the world is fair, so good people do well and bad people get punished. Because of this belief, people who see someone suffer unfairly may think the person must have done something wrong, which is known as victim blaming.

Is belief in a just world purely harmful?

No. A personal belief that the world is fair to you helps you plan and work toward the future and is linked to well-being. But a strong general belief can lead to blaming victims and the poor.
