This experiment fits into a large body of psychological literature about something called “the fundamental attribution error.” The word attribution refers to the tendency to explain people’s behavior in terms of either “dispositional” factors—in other words, the kind of person they are—or “situational” factors, like whether they happen to be late for a talk. The word error refers to the fact that these attributions are often wrong, that we tend to underestimate the role of situation and overestimate the role of disposition. In other words, we’re biased in favor of essence.
