Dr. Steven Hayes is one of the most cited psychologists in the world. He was listed by the Institute for Scientific Information as the 30th "highest impact" psychologist worldwide and is the author of 46 books and nearly 650 scientific articles. His career has focused on an analysis of the nature of human language, cognition, and the application of this for the understanding and alleviation of human suffering.

He's also the developer of Relational Frame Theory, an account of human higher cognition, and has guided its extension to Acceptance and Commitment Therapy (ACT), a popular evidence-based form of psychotherapy that uses mindfulness, acceptance, and values-based methods.

In this episode, we discuss the importance of psychological flexibility, why mental suffering is optional, how our minds have created a virtual reality, theory of mind, psychedelics, lucid dreaming, utopias, and of course his famous form of psychotherapy, ACT.
