for their suffering. During his clinical training as a psychologist, he observed treatment of mentally ill persons by the health care practitioners with whom he worked. Although Lerner knew them to be kindhearted, educated people, they often blamed patients for the patients' own suffering. Lerner also describes his surprise at hearing his students derogate (disparage, belittle) the poor, seemingly oblivious to the structural forces that contribute to poverty. The desire to understand the processes that caused these phenomena led Lerner to conduct his first experiments on what is now called the just-world hypothesis. Early evidence 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 for her errors during a learning task (learning pairs of nonsense syllables). 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. Lerner and colleagues replicated these findings in subsequent studies, as did other researchers. Theory 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. 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
