Donald Hoffman

Donald Hoffman (1955–present) is a cognitive scientist (UC Irvine) whose research on perception and evolutionary game theory led him to a striking thesis, set out in The Case Against Reality (2019): evolution shaped our senses for fitness, not truth, so the world we perceive (space, time, objects) is a species-specific “user interface,” not reality as it is.

From this he builds “conscious realism” — the bolder metaphysical claim that consciousness is fundamental and that physical reality (including spacetime) emerges from a substrate of interacting “conscious agents.” Hoffman’s work spans tiers.

The empirical and game-theoretic core — that perception is tuned for fitness and that “spacetime is doomed” as a fundamental category (echoing some physicists) — engages with legitimate science. But “conscious realism” and his formal “conscious agents” model are speculative metaphysics, not established results, and are not accepted by mainstream cognitive science or physics.

Because his idealism is dressed in mathematics and evolutionary theory, it is heavily adopted by spiritual, manifestation, and simulation-theory communities as scientific proof that “reality is a projection of consciousness” and therefore malleable by mind.

Hoffman himself is cautious about manifestation-style claims, but his framework is among the most directly enlisted bridges from academic cognitive science to consciousness-creates-reality belief. Tier: legitimate-science (interface theory) versus speculative/contested (conscious realism); routinely over-extended toward manifestation.
