Researchers at UC Berkeley are doing a wide range of studies exploring positive emotions and happiness. Experiments on the brain, nervous system, hormones, heart, and social interaction are indicating that human nature and the survival of the species rely much more on compassion, gratitude, trust, and altruism than previously thought. The theory of "survival of the fittest" is giving way to "survival of the kindest." Psychologists Dacher Keltner, Rudy Mendoza-Denton, and sociologists Rob Willer and Christina Carter discuss their work and its implications for society.
