Just-world Hypothesis

The just-world hypothesis (or just-world fallacy) is the cognitive bias that human actions eventually yield morally fair and fitting consequences, so that, ultimately, noble actions are duly rewarded and evil actions are duly punished. In other words, the just-world hypothesis is the tendency to attribute consequences to, or expect consequences as the result of, an unspecified power that restores moral balance; the fallacy is that this implies (often unintentionally) the existence of such a power in terms of some cosmic force of justice, desert, stability, or order in the universe.

The fallacy popularly appears in the English language in various figures of speech, which often imply a negative reprisal of justice, such as: "You got what was coming to you," "What goes around comes around," and "You reap what you sow." This phenomenon of this fallacy 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. Since that time, research has continued, examining the predictive capacity of the hypothesis in various situations and across cultures, and clarifying and expanding the theoretical understandings of just world beliefs.
