What is free will, really? Steven Pinker explains.

TL;DR

Free will is a complex neurophysiological process influenced by various factors, not defying physical laws.

Transcript

I do believe that there is such a thing as free will but by that I do not mean that there is some process that defies the laws of physical cause and effect. As my colleague Joshua Greene once put it, it is not the case that every time you make a decision a miracle occurs. So I don't believe that. I believe that decisions are made by neurophysiologi...

Key Insights

• 👮 Free will is not a miraculous process but a complex neurophysiological one bound by physical laws.
• 💁 Decision-making integrates various information streams, such as memory, goals, environment, and external expectations.
• 👏 Free will responds to consequences, including rewards, punishments, praise, and blame, shaping behavioral choices.
• 👻 Unpredictability in decision-making does not involve a ghost in the machine but reflects the brain's complexity.
• 🥶 Identical twins facing the same choices may make different decisions, highlighting the non-deterministic nature of free will.
• 🥶 The existence of free will is valuable as it aligns with expectations of consequences, influencing people's choices.
• 🥶 While most individuals follow societal norms and expectations, free will allows for variability in decision-making.

Questions & Answers

Q: Is free will a process that defies physical cause and effect?

No, free will operates within the laws of physics, determined by neurophysiological processes in the brain that integrate various information streams to make decisions.

Q: How does free will differ from reflexive behaviors?

Free will involves a more deliberate and complex process influenced by memory, goals, current environment, and external expectations, distinct from reflexive and predictable behaviors.

Q: Why is free will influenced by consequences?

Free will responds to expectations of reward, punishment, praise, and blame as individuals factor in how their choices will be treated, impacting their decision-making processes.

Q: Is free will completely predictable?

Free will is not entirely predictable due to potential random, chaotic, or nonlinear effects, leading to variability in decision-making even in similar circumstances.

Summary & Key Takeaways

• Free will is not a miraculous process, but a neurophysiological one bound by physical laws.

• Decisions involve a deliberative, complex process integrating diverse information streams.

• Free will responds to expectations of reward, punishment, praise, and blame, influencing choices.
