Karen believes that the reason someone cut in front of her on the road is because the person is out to get her. However, when she cuts off a person a few miles later, she believes it is because she needed to get over to the right lane to make a turn. In this example, Karen is demonstrating:

The actor-observer effect or bias is a socio-psychological term used to describe human perception to interpret situations in a biased way.

The actor-observer effect or bias occurs when individuals associate their actions to external reasons but attribute other people's actions to internal reasons.
