Ryan Martin: Why we get mad -- and why it's healthy (2019x135)

:

Anger researcher Ryan Martin draws from a career studying what makes people mad to explain some of the cognitive processes behind anger — and why a healthy dose of it can actually be useful. "Your anger exists in you ... because it offered your ancestors, both human and nonhuman, an evolutionary advantage," he says. "[It's] a powerful and healthy force in your life."
