Dr. Robert Sapolsky: Science of Stress, Testosterone & Free Will | Huberman Lab Podcast #35

Illusion

Robert Sapolsky argues that free will is an illusion, challenging the views of many philosophers and neuroscientists. He explains that our behaviors and choices are influenced by a myriad of factors, from sensory environments and hormone levels to cultural backgrounds and genetic makeup 1. Understanding these influences leaves no room for the concept of free will in our brains 1. Sapolsky's upcoming book, "Determined: The Science of Life Without Free Will," aims to convince readers of this perspective and explores the implications of living without the notion of free will 2.

If any angers and hatreds you feel aren't justified, if there's no such thing as appropriate blame or punishment or praise or reward and none of it makes any sense.

--- Robert Sapolsky

Sapolsky acknowledges the difficulty of functioning without believing in free will but emphasizes that society has historically adapted to new understandings of human behavior 2.

   

Knowledge

Andrew Huberman and Sapolsky discuss how knowledge and perception of control influence our sense of free will and decision-making. Sapolsky asserts that while we cannot change ourselves volitionally, we can be changed by our circumstances and knowledge 3. This understanding can make us more open to positive changes and resistant to discouragement 4.

The knowledge of the knowledge is an effector in and of itself.

--- Robert Sapolsky

Huberman highlights the importance of neuroplasticity, suggesting that learning about how our brains work can itself alter our neural circuitry and behavior 4.
