Ultimate Attribution Error

We attribute positive acts of out-group members to luck and negative acts to their character.

Not enough meaning Filling gaps from stereotypes

The ultimate attribution error is a type of attribution error which describes how attributions of causality are affected by the groups to which people belong. In-group members' positive behaviors are attributed to character; negative behaviors to circumstance. For out-group members, the attribution is reversed. This perpetuates prejudice by making disconfirming evidence (an out-group member doing something good) seem like an exception.

Where it shows up

What it looks like in the wild.

Would you catch it?

Recognising a definition is not the same skill as spotting it.

Two scenarios from the app, with distractors drawn from the same family of biases — which is what makes them hard.

Scenario 1Which bias?

When an out-group member succeeds, it is attributed to favorable circumstances, but when an in-group member succeeds at the same task, it is seen as evidence of inherent talent.

Scenario 2Which bias?

Your colleague from the rival team delivered an excellent presentation. You think they must have gotten lucky with the data they were given. Later, they made a small error in an email, and you conclude they're just not very detail-oriented.
