Evolution science and behavioral science both have strong theories that can help us understand humans in context, and yet, until now, the two fields have been mostly separate. In this episode, Dr. Steven Hayes and Dr. David Sloan Wilson share how they are collaborating to bridge this divide. They discuss their recent co-edited book, Evolution and Contextual Behavioral Science: An Integrated Framework for Understanding, Predicting, and Influencing Human Behavior, and they explore about how taking an evolutionary view of humans can be helpful in daily life, and in psychotherapy practice.
