The critical factor in understanding behavior is the intent behind it, rather than just the action itself. Assessing behavior without considering the intent is likened to judging a movie based only on its last three minutes. Understanding the origin of intent opens up a broader perspective, involving considerations such as brain function, environmental triggers, hormone levels, trauma, and fetal development. The brain's structure and functioning are heavily influenced by past experiences, and even the prenatal environment plays a significant role in shaping an individual's brain development.
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.
