## What it is

Assuming outcomes are deserved, so misfortune implies fault.

## In the wild

> He lost his job, so he must have deserved it.

## How to answer it

Ask what role chance, timing, and circumstance played in the outcome.

## Origin and naming

Psychologist Melvin Lerner named the belief in a just world in the early 1960s and documented it at the University of Kansas in 1966, where observers of a suffering victim, unable to help, came to derogate her instead. He summarized the work in The Belief in a Just World: A Fundamental Delusion (1980).

## More places it shows up

- Reading about the investor who lost everything to a fraud, the comments decide he was greedy and the scheme 'only takes in people who want shortcuts'.
- After the layoff, colleagues explain the cut among themselves: 'She never really fit the culture' — a verdict that arrives only after the verdict did.
- A neighbor hears about the car accident on the highway and immediately knows the driver must have been speeding.
- On a help forum, someone who was locked out of their account by a platform error is told to check what they did to trigger the flag.

## How to spot it

- The story rearranges itself so the victim's character arrives just in time to explain the event.
- The search for what they did wrong starts only after the bad thing happened — the outcome picks the evidence.
- Ask what role chance played and the reply treats luck as an accusation, not a factor.
