Chemical Decisions

What this episode covers

This episode of Can You Predict the Past? examines free will from a biological perspective, with Kaden Proa and Nate discussing whether our choices are determined by brain activity or if true autonomy exists. They conclude that while biology—such as hunger, instincts, genetics, and brain chemistry—strongly influences behavior, it does not fully control it. Nate introduces the idea that the brain produces urges, but a separate sense of “self” or free will can override those impulses, especially in cases like addiction or discipline. The conversation also highlights that environment and upbringing often shape decisions more than genetics alone, and that habits formed early in life can redirect biological tendencies. Despite these influences, both agree that people are still responsible for their actions and cannot simply blame biology. The episode ultimately argues that free will exists in the ability to consciously resist or act against natural instincts, emphasizing that real control comes from choosing how to respond to the pressures of our biology.
