the fundamental attribution error: a tendency to think that people's actions are due to their personality/disposition, not to their situation/environment.
e.g. someone doesn't anwer a message you left. You think "this person is a jerk" or "this person doesn't like me". In fact, they may be just struggling with a situation that made it hard to text back.
We all have this bias. Empathy lies in the ability to deal with the fundamental attribution error
