““Some years ago, two social psychologists, Edward Jones and Richard Nisbett, argued that when it comes to explaining people's behavior-something like achievement problems, for example there is a big difference between the "observer's perspective"-the perspective of a person observing the behavior-and the "actor's perspective"-the perspective of a person doing the behavior. As observers, Jones and Nisbett said, we're looking at the actor, the person doing the behavior we are trying to explain. Thus the actor dominates our literal and mental visual field, which makes the circumstances to which he is responding less visible to us. In the resulting picture in our minds, the actor sticks out like a sore thumb and the circumstances to which he is responding are obscured from view. Jones and Nisbett held that this picture causes a bias when we try to explain the actor's behavior. We emphasize the things we can see. We emphasize things about the actor-characteristics, traits, and so on-that seem like plausible explanations for her behavior. And we deemphasize, as causes of her behavior, the things we can't see very well, namely, the circumstances to which she is adapting.””
