"The fundamental attribution error (also known as correspondence bias or over-attribution effect) is the tendency for people to over-emphasize dispositional, or personality-based explanations for behaviors observed in others while under-emphasizing situational explanations.

In other words, people have a cognitive bias to assume that a person's actions depend on what "kind" of person that person is rather than on the social and environmental forces that influence the person."
