Robert Sapolsky, PhD is an author, researcher, and professor of biology, neurology, and neurosurgery at Stanford University. In this interview with Big Think’s Editor-in-Chief, Robert Chapman Smith, Sapolsky discusses the content of his most recent book, “Determined: The Science of Life Without Free Will.”

Being held as a child, growing up in a collectivist culture, or experiencing any sort of brain trauma – among hundreds of other things – can shape your internal biases and ultimately influence the decisions you make. This, explains Sapolsky, means that free will is not – and never has been – real. Even physiological factors like hunger can discreetly influence decision making, as discovered in a study that found judges were more likely to grant parole after they had eaten.

This insight is key for interpreting human behavior, helping not only scientists but those who aim to evolve education systems, mental health research, and even policy making.
