In this episode, we explore the Fun Criterion, a powerful idea of David Deutsch that helps us take action in a way that’s both enjoyable and effective. Rather than relying on discipline or forcing ourselves through tasks, the Fun Criterion urges us to take all parts of our mind seriously—our Statements, Intuitions, and Drives. We unpack what “Fun” really means in this context, why coercion undermines problem-solving, and how to recognize when you’re in a state of fun. We also discuss practical ways to apply the Fun Criterion in daily life.
