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.
