this is the tendency to react to horrible misfortune, like homelessness or drug addiction, by believing the people stuck in these situations must have done something to deserve it. The key word there is “deserve.” This is not an observation that bad choices may lead to bad outcomes. The just-world fallacy helps you to build a false sense of security. You want to feel in control, so you assume as long as you avoid bad behavior, you won’t be harmed. You feel safer when you believe those who engage in bad behavior end up on the street, or pregnant, or addicted, or raped.
