Robert Sapolsky, a renowned neuroscientist and Stanford professor, dives into the intriguing interplay between determinism and free will. He argues that factors like genetic background and environment shape our behavior and decision-making, challenging traditional notions of accountability. The discussion reveals how even subtle environmental cues, like smells, can impact our beliefs and actions. Sapolsky encourages a compassionate reevaluation of societal structures and moral responsibility, emphasizing that understanding determinism may lead to a more empathetic approach to individual circumstances.
Human behavior is preordained and determined by a combination of biological, genetic, and environmental factors.
Accepting determinism challenges the notions of accountability and meritocracy, leading to a more compassionate and understanding society.
Recognizing the influence of biology and environment on behavior can lead to a justice system focused on rehabilitation rather than punishment.

The Illusion of Free Will
In this podcast episode, neuroscientist and author Robert Sapolsky discusses his book 'Determined: A Science of Life Without Free Will.' Sapolsky argues that there is no free will and that human behavior is preordained and determined by a combination of biological, genetic, and environmental factors. He presents evidence from various fields, including neuroscience and social science, to support his viewpoint. Sapolsky explores examples such as how sensory stimuli like smells can influence our political views, how the socioeconomic status of a fetus's mother can affect brain development, and how cultural factors shape behaviors like honor systems. He acknowledges the discomfort and resistance people may have to accepting the notion of determinism and reflects on the implications of this understanding for concepts like regret, blame, and moral responsibility.
The Challenge of Accepting Determinism
Sapolsky acknowledges that accepting the idea of determinism can be challenging for individuals who are accustomed to thinking of themselves as having free will. He discusses the tendency to view consciousness and the human experience as distinct from other organisms. Sapolsky highlights that while humans possess consciousness and self-awareness, these qualities do not change the fundamental fact that we are biological machines, driven by instinct and influenced by a complex interplay of genetic and environmental factors. He explores the deeply rooted cultural and personal discomfort with the idea of determinism and reflects on the implications for concepts such as regret, judgment, and moral responsibility.
The Relationship Between Belief and Behavior
Sapolsky addresses the concerns that embracing determinism would lead to a breakdown of ethical behavior and social order. He presents research studies that demonstrate how individuals' belief in free will or determinism does not necessarily correlate with their moral behavior. Whether someone believes in free will or accepts determinism, their actions are shaped by a combination of biological, genetic, and environmental factors. Sapolsky explains that accepting determinism does not imply that people will 'run amok' or abandon moral norms. He emphasizes that understanding the factors influencing human behavior allows for a more comprehensive analysis of actions and behaviors, with implications for our legal, social, and ethical frameworks.
Our view of the world as a meritocracy is flawed
Our perception of the world as a meritocracy is flawed as we tend to forget the differences that interfere with this view. We praise the success of individuals who graduate but often overlook the different backgrounds and opportunities that people have. It is important to recognize that each person has a unique genetic endowment and upbringing, which influences their abilities and choices. Judging and blaming others becomes unjust when we understand that everyone's circumstances are different.
The implications of a world without free will
In a world without free will, where our actions and behaviors are a result of biology and environment, it becomes difficult to assign blame or reward. This challenges the notions of accountability and meritocracy. While it may be disheartening to realize that we haven't truly earned our achievements, it opens up the possibility for a more compassionate and understanding society. By recognizing that people's behaviors and choices are influenced by factors beyond their control, we can create a justice system that focuses on rehabilitation rather than punishment. Embracing this perspective can lead to a more humane and empathetic world.
Your mother's socio-economic status at the time of your birth. Whether your ancestors raised crops or led camels through the desert. The smell of the room you're in when you're making a decision--all of these things, says neuroscientist Robert Sapolsky, combine to affect your behavior, as well as everything in between. And if you're wondering where free will fits in, Sapolsky says, it doesn't: If we're all the sum of our biology and environments over which we had no control, it makes no sense to hold us accountable for anything that we do. In a conversation that's equal parts fascinating and frightening, Sapolsky and EconTalk's Russ Roberts discuss the science and philosophy behind determinism. They explore what this argument, taken to its logical conclusion, means for our social and legal systems, and the challenge of how to live if free will is an illusion.
