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."

Strength represents the power of gentle persuasion and inner fortitude over brute force. It signifies the ability to tame the wilder aspects of oneself with compassion and patience.
Ryan Martin’s talk maps to Strength because it treats anger as powerful life-force that carries useful information and calls for wise handling. He explains that anger often arises when something feels unfair, avoidable, blocking, or powerless, and he argues that anger can alert us to injustice. Strength is the tarot archetype of meeting heat, instinct, and intensity with courage, calm, and conscious direction, so it fits this talk with unusual precision.
