Do We See Reality As It Is?: A Discussion With Cognitive Scientist Donald Hoffman

We Had the Pleasure to speak with Dr. Hoffman about his Interface Theory of Perception and Conscious Agents. Group members were able to ask Dr. Hoffman questions during this seminar style event. ABSTRACT Our perceptual capacities are products of evolution and have been shaped by natural selection. It is often assumed that natural selection favors veridical perceptions, namely, perceptions that accurately describe those aspects of the environment that are crucial to survival and reproductive fitness. However, analysis of perceptual evolution using evolutionary game theory reveals that veridical perceptions are generically driven to extinction by equally complex non-veridical perceptions that are tuned to the relevant fitness functions. Veridical perceptions are not, in general, favored by natural selection. This result requires a comprehensive reframing of perceptual theory, including new accounts of illusions and hallucinations. This is the intent of the interface theory of perception, which proposes that our perceptions have been shaped by natural selection to hide objective reality and instead to give us species-specific symbols that guide adaptive behavior in our niche. BIO Donald Hoffman received a PhD from MIT, and is a Professor Emeritus of Cognitive Sciences at the University of California, Irvine. He is an author of over 120 scientific papers and three books, including The Case Against Reality: Why Evolution Hid the Truth from Our Eyes. He received a Distinguished Scientific Award of the American Psychological Association for early career research, the Rustum Roy Award of the Chopra Foundation, and the Troland Research Award of the US National Academy of Sciences. His writing has appeared in Scientific American, New Scientist, LA Review of Books, and Edge, and his work has been featured in Wired, Quanta, The Atlantic, Ars Technica, National Public Radio, Discover Magazine, and Through the Wormhole with Morgan Freeman. He has a TED Talk titled “Do we see reality as it is?”
