The just-world hypothesis or just-world fallacy is the cognitive bias that assumes that “people get what they deserve” – that actions will have morally fair and fitting consequences for the actor. For example, the assumptions that noble actions will eventually be rewarded and evil actions will eventually be punished fall under this hypothesis. In other words, the just-world hypothesis is the tendency to attribute consequences to—or expect consequences as the result of— either a universal force that restores moral balance or a universal connection between the nature of actions and their results. This belief generally implies the existence of cosmic justice, destiny, divine providence, desert, stability, and/or order. It is often associated with a variety of fundamental fallacies, especially in regard to rationalizing suffering on the grounds that the sufferers “deserve” it.
The hypothesis popularly appears in the English language in various figures of speech that imply guaranteed punishment for wrongdoing, such as: “you got what was coming to you“, “what goes around comes around“, “chickens come home to roost“, “everything happens for a reason”, and “you reap what you sow“. This hypothesis has been widely studied by social psychologists since Melvin J. Lerner conducted seminal work on the belief in a just world in the early 1960s.[1] Research has continued since then, examining the predictive capacity of the hypothesis in various situations and across cultures, and clarifying and expanding the theoretical understandings of just-world beliefs.[2]
In 1966, Lerner and his colleagues began a series of experiments that used shock paradigms to investigate observer responses to victimization. In the first of these experiments conducted at the University of Kansas, 72 female participants watched what appeared to be a confederate receiving electrical shocks under a variety of conditions. Initially, these observing participants were upset by the victim’s apparent suffering. But as the suffering continued and observers remained unable to intervene, the observers began to reject and devalue the victim. Rejection and devaluation of the victim was greater when the observed suffering was greater. But when participants were told the victim would receive compensation for her suffering, the participants did not derogate the victim.[6] Lerner and colleagues replicated these findings in subsequent studies, as did other researchers.[8]
To explain these studies’ findings, Lerner theorized that there was a prevalent belief in a just world. A just world is one in which actions and conditions have predictable, appropriate consequences. These actions and conditions are typically individuals’ behaviors or attributes. The specific conditions that correspond to certain consequences are socially determined by a society’s norms and ideologies. Lerner presents the belief in a just world as functional: it maintains the idea that one can influence the world in a predictable way. Belief in a just world functions as a sort of “contract” with the world regarding the consequences of behavior. This allows people to plan for the future and engage in effective, goal-driven behavior. Lerner summarized his findings and his theoretical work in his 1980 monograph The Belief in a Just World: A Fundamental Delusion.[7]
Lerner hypothesized that the belief in a just world is crucially important for people to maintain for their own well-being. But people are confronted daily with evidence that the world is not just: people suffer without apparent cause. Lerner explained that people use strategies to eliminate threats to their belief in a just world. These strategies can be rational or irrational. Rational strategies include accepting the reality of injustice, trying to prevent injustice or provide restitution, and accepting one’s own limitations. Non-rational strategies include denial, withdrawal, and reinterpretation of the event.[9]
