By the time you feel the anger, your body has already set off. That feeling is news arriving late, not proof that you have failed at anything.

What the research says

In a randomised controlled trial, brief internet treatments that taught either mindful awareness of emotion or cognitive reappraisal both reduced problematic anger, with no clear advantage to combining them. Attending to what is happening in you seems to help, and it is not the only route that works. It was a short, therapist-supported online programme, so it says more about the direction than about how much.

Strength of evidence: one line of research. A single study, or a theoretical account.
