Is Reality Really Real? With Donald Hoffman
Jun 26, 2026 · 1h 14m
Summary
Neil deGrasse Tyson, Gary O'Reilly, and Chuck Nice interview cognitive scientist Donald Hoffman, who argues evolution shaped perception as a survival-focused VR headset rather than a window to objective reality. Hoffman uses evolutionary game theory to claim the probability of seeing true reality is zero, suggesting consciousness is fundamental while space-time emerges from it. The discussion explores simulation theory, the limits of scientific measurement, and potential experiments using DMT to test if altered states access higher dimensions.
