Mark Miller's background and research focus

In this episode of The Lectern, host Ethan Hsieh sits down with philosopher and cognitive scientist Mark Miller to explore the science of predictive processing and its implications for happiness, meaning, and wellbeing.

They unpack how the brain is not a passive receiver of reality, but an active prediction engine—constantly generating its best guesses about the world and updating them through experience. From belief formation and perception to resilience, virtue, play, and mindfulness, the conversation bridges cutting-edge cognitive science with ancient contemplative wisdom.

Together, Ethan and Mark discuss how understanding the predictive nature of the mind can transform how we relate to uncertainty, cultivate agency, and develop a deeper, more participatory sense of happiness—both individually and collectively.

This episode also introduces Mark Miller's upcoming course, Generations of Joy, which explores these ideas through neuroscience, philosophy, and contemplative practice.
