Our conscious mind plays a much smaller role in our decision-making and behavior than we believe. The vast majority of our brain's operations occur in the subconscious realm, from basic survival responses to complex problem-solving, often making decisions before we're consciously aware of them.

The human brain consists of competing neural networks that simultaneously process different possibilities and outcomes. This complex system explains why we can hold contradictory beliefs, struggle with internal conflicts, and sometimes act in ways that seem to defy our conscious intentions.

Our understanding of the brain's role in behavior raises profound questions about free will, personal responsibility, and the justice system. Eagleman challenges traditional notions of culpability by examining how biological factors influence human behavior and decision-making.
