After Lerner's first studies, other researchers replicated these findings in other settings in which individuals are victimized. This work, which began in the 1970s and continues today, has investigated how observers react to victims of random calamities like traffic accidents, as well as rape and
domestic violence, illnesses, and poverty. In the early 1970s, social psychologists
Zick Rubin and Letitia Anne Peplau developed a measure of belief in a just world. This measure and its revised form published in 1975 allowed for the study of individual differences in just-world beliefs. Much of the subsequent research on the just-world hypothesis used these
measurement scales. These studies on victims of
violence,
illness, and
poverty and others like them have provided consistent support for the link between observers' just-world beliefs and their tendency to blame victims for their suffering. These findings have been replicated repeatedly, including using a rape ending and a "happy ending" (a marriage proposal). Other researchers have found a similar phenomenon for judgments of
battered partners. One study found that observers' labels of blame of female victims of relationship violence increase with the intimacy of the relationship. Observers blamed the perpetrator only in the least intimate case of violence, in which a male struck an acquaintance.
Bullying Researchers have employed the just-world fallacy to understand
bullying. Given other research on beliefs in a just world, it would be expected that observers would derogate and blame bullying victims, but the opposite has been found: individuals high in just-world belief have stronger anti-bullying
attitudes. Other researchers have found that strong belief in a just world is associated with lower levels of bullying behavior. This finding is in keeping with Lerner's understanding of belief in a just world as functioning as a "contract" that governs behavior. as has been shown for the
general population.
Illness Other researchers have found that observers judge sick people as responsible for their illnesses. One experiment showed that persons suffering from a variety of illnesses were derogated on a measure of attractiveness more than healthy individuals were. In comparison to healthy people, victim derogation was found for persons presenting with indigestion, pneumonia, and stomach cancer. Moreover, derogation was found to be higher for those suffering from more severe illnesses, except for those presenting with cancer. Stronger belief in a just world has also been found to correlate with greater derogation of
AIDS victims.
Poverty More recently, researchers have explored how people react to poverty through the lens of the just-world fallacy. Strong belief in a just world is associated with blaming the poor, with weak belief in a just world associated with identifying external causes of poverty including world economic systems,
war, and
exploitation.
The self as victim Some research on belief in a just world has examined how people react when they themselves are victimized. An early paper by Dr. Ronnie Janoff-Bulman found that rape victims often blame their own behavior, but not their own characteristics, for their
victimization. It was hypothesized that this may be because blaming one's own behavior makes an event more
controllable. ==Theoretical refinement==
