We all fail at anger.
In the recalibration theory of anger, anger does not only exist as an emotional response to our needs to be met by others, but it also exists as a way to build community. Because in the field of evolutionary psychology, the argument is that anger exists because we also expect others to take our anger seriously and value in an empathetic way. What is the recalibration theory of anger, you ask?

The recalibration theory of anger is a computational-evolutionary model that maintains that the function of anger is to recalibrate individuals who place insufficient weight on the welfare of the angry individual when making decisions in short when others are angry and we do nothing to understand it, we dismiss our responsibility to validate their emotional experience — which also diminishes the communal spirit that inhabits us all.
We deny the opportunity to build that community that evolutionary psychology claims are the reason why we get angry. When we don’t take someone else’s’ emotional experience as real, we deny the human bond altogether.
