The just-world hypothesis (also called the just-world theory, just-world fallacy, just-world effect, or just-world phenomenon) refers to the tendency for people to want to believe that the world is fundamentally just. As a result, when they witness an otherwise inexplicable injustice, they will rationalize it by searching for things that the victim might have done to deserve it. This deflects their anxiety, and lets them continue to believe the world is a just place, but often at the expense of
blaming victims for things that were not, objectively, their fault.
