On the hypothesis that the subject becomes angry, and wants to hurt the other person, we might predict that the subject will > take any of many possible avenues to revenge - a kick, a trip, a bite, a phone call two months later that leads the confederate's wife and girlfriend to the same hotel... All of these I can predict by saying, "The subject is angry, and wants revenge."

Is it not fake causality to show a variety of different outcomes, all for the exact same reason?

Or perhaps is the point that saying 'angry' increases the probability of certain responses to other?
