One of our great behavioural scientists, the bestselling author of Behave, dives to the depths of the science and the philosophy of decision-making to mount a devastating case against free will, an argument with profound consequences. After listening, ask yourself, what side are you on?

Are we indeed the masters of our fate, or is free will nothing more than an illusion? In this week’s episode, I sit down with renowned neuroscientist and Stanford professor Dr. Robert Sapolsky to explore the provocative ideas from his groundbreaking book, Determined: A Science of Life Without Free Will.

Sapolsky argues that our choices—from our morning coffee to major life decisions—are entirely shaped by biology and environment, leaving no room for free will. We dive into the science behind human behaviour, the randomness of life, and the implications of viewing ourselves as “biological machines.”

This thought-provoking conversation challenges everything we think we know about accountability, morality, and transformation. Can we truly change? How do we raise children in a world without free will? And could letting go of the notion of free will make the world a more compassionate place?

From personal anecdotes about Sapolsky’s early questioning of faith and free will to his fascinating insights into human biology and culture, this episode will leave you questioning whether you are truly in control—or just along for the ride.
