It’s become fashionable to argue that free will is a fiction: that we humans are in the thrall of animal urges and unconscious biases and only think that we are choosing freely. In Freely Determined, research psychologist Kennon Sheldon argues that this perception is not only wrong but also dangerous.

Shermer and Sheldon discuss: definitions of free will, determinism, compatibilism, libertarian free will • dualism • reductionism, materialism, predetermination, and epiphenomenalism • Christian List’s three capacities for free will • AI, Star Trek’s Data, sentience and consciousness, ChatGPT, GPT-4 • how what people believe about free will and determinism influences their behaviors • the case for hard determinism • brain injuries, tumors, addictions, and other “determiners” of behavior • emergence • symbolic self • System 1 vs. System 2 thinking •  Experiencing Self vs. Remembered Self •  subjective well-being and happiness.
