Fundamental Attribution Error or Person Bias

The fundamental attribution error is a tendency for people to assign personal attributes to a behaviour, and to discard situational factors, when making judgments about the behaviour of others. An example is of seeing someone driving on a motorway at under half the speed limit. One might automatically assume that the person is deliberately driving slowly, but the slow driving may in fact be due to other factors such as a mechanical problem.
