Donald David Hoffman (born December 29, 1955) is an American cognitive psychologist and popular science author. He is a professor emeritus in the Department of Cognitive Sciences at the University of California, Irvine. Hoffman studies consciousness, visual perception, and evolutionary psychology using mathematical models and psychophysical experiments. His research subjects include facial attractiveness, the recognition of shape, the perception of motion and color, the evolution of perception, and the mind–body problem. He has co-authored two technical books; Observer Mechanics: A Formal Theory of Perception (1989) offers a theory of consciousness and its relationship to physics; Automotive Lighting and Human Vision (2005) applies vision science to vehicle lighting. His book Visual Intelligence: How We Create What We See (1998) presents the modern science of visual perception to a broad audience. His 2015 TED Talk, "Do we see reality as it is?" argues that our perceptions have evolved to hide reality from us. He followed this up with a book in 2019, The Case Against Reality: How Evolution Hid the Truth from Our Eyes.
