Fundamental Attribution Error
When a problem with a person is really a problem with the situation.
We tend to attribute people’s behavior to their core character rather than to their situation. It's the Situation, Not the Person.
“What a jerk!... see how he drives!”
“Fundamental Attribution Error honey, I wonder the situation he’s in that’s causing him to drive so crazy.”

"What do you mean?"
"He is the doctor in charge of emergency at the hospital few blocks away... don´t you remember?"
