This Paradox Splits Smart People 50/50
This documentary explores Newcomb’s Paradox, a thought experiment in decision theory that presents a choice between two boxes, one of which may contain a substantial sum of money. The paradox highlights a conflict between two principles of rational choice: maximizing expected utility and acting causally. The scenario involves a predictor who has foreknowledge of the participant’s choice, leading to divergent strategies among individuals.
The program delves into the historical context and philosophical implications of Newcomb’s Paradox, examining how it challenges conventional understandings of rationality, free will, and the nature of prediction. It features contributions from several academics, including Dr. Arif Ahmed, Dr. Adam Elga, Dr. Kenny Easwaran, Dr. Peter Slezak, Dr. David Wolpert, Dr. Scott Aaronson, and Dr. Michael Huemer, who provide insights into the various approaches to resolving the paradox.

Frequently Asked Questions
What is Newcomb’s Paradox?
Newcomb’s Paradox is a thought experiment involving a choice between two boxes, where a predictor has accurately foreseen the participant’s decision. One box is transparent and contains a known amount, while the other is opaque and may contain a larger sum, depending on the predictor’s forecast of the participant’s choice.
How does Newcomb’s Paradox relate to free will?
The paradox raises questions about the nature of free will by suggesting that a predictor can accurately foresee a person’s choices, which can be interpreted as implying a deterministic universe or challenging the traditional understanding of autonomous decision-making.
What is decision theory?
Decision theory is an interdisciplinary approach to identifying the values, uncertainties, and other issues relevant to a given decision, its rationality, and the resulting optimal choice. It encompasses various frameworks, including causal and evidential decision theory, which offer different perspectives on how to make rational choices under uncertainty.
