Imagine slipping into a multiplayer VR version of Grand Theft Auto, racing cars against players scattered across the world. You see a red Corvette speeding beside you. You immediately grip the steering wheel of your matte-black Porsche 911, slam the virtual gas pedal, and tear through the glowing digital streets of Los Santos chasing after it. How dare the Corvette come for your crown? Now, if someone logically asked you, after taking off the headset, whether the rival car was true reality, you’d likely laugh and say no. You can grasp, even faintly, that what you experienced existed as millions of bits being toggled in precise sequences at blinding speed somewhere inside a supercomputer. There is no actual Corvette inside that machine. For Donald Hoffman, PhD, a cognitive scientist at the University of California, Irvine, this may be the best metaphor for reality itself. “We’re playing a multiplayer game,” he says. “My body is just an avatar in a VR game. It’s not the truth.”
In Hoffman’s “interface theory” of perception, evolution shaped us not to perceive objective reality directly, but to experience a simplified survival interface. Just as a VR game hides the incomprehensible complexity of the underlying code, Hoffman argues that space-time may function more like a navigational dashboard than objective reality itself. In such an interface, our senses evolved not to reveal the truth, but simply to help us play the game of life. And after a while, the game becomes so immersive that we lose ourselves inside it, thinking our avatars are all there is.
Hoffman arrived at the theory through an unusual reading of Darwinian evolution. If natural selection rewards survival rather than truth, he wondered, why assume humans evolved to perceive “raw” reality accurately at all? Then he turned to evolutionary game theory, which is a mathematical framework for modeling survival and competition.
In these mathematical models, organisms survive not by discovering objective truth, but by maximizing what scientists call “payoff functions,” which are strategies that increase the odds of survival and reproduction. A hungry lion chasing a gazelle, for example, receives a high evolutionary payoff. A hungry lion trying to eat a rock receives almost none, Hoffman says. Over time, evolution preserves the sensory systems associated with successful payoffs, not necessarily the ones that perceive reality accurately.
That realization led him to what he considers the theory’s most radical implication. Mathematically, Hoffman says, the question becomes whether the sensory shortcuts favored by evolution preserve the true structure of reality itself. Using evolutionary game theory models, he argues they do not. “What’s the probability that, you know, I see a rock because there really is a rock? I see the tree because there really is a tree?” he asks. “The answer is 0 percent. Exactly 0 percent.”
Natural selection, he says, never shaped organisms to perceive objective reality accurately, but simply to survive long enough to reproduce. It made us competent enough to navigate the world through simplified survival shortcuts—a user interface optimized for fitness rather than truth.
“Most of us think that means we’ve been shaped to see reality, because of course seeing reality would make you more fit,” Hoffman says. “And the answer is no. Period… When you do the math, the probability that seeing the truth will help you reproduce is zero.”
But if the body is merely an avatar inside the interface, where exactly is the “real” self, the consciousness? This is a question we shouldn’t even be asking, according to Hoffman. Because the true self is “nowhere in the game.”
“The very notion of being in the game is just wrong for who you really are,” Hoffman says. Questions like “Where am I? When am I?” assume that we are thinking in terms of space and time coordinates. But this returns us back into the VR headset—the trap of space-time itself. “Whatever you really are transcends the very notions of where and when,” he says. In other words, the very interface that allows us to navigate reality may also prevent us from perceiving what we truly are beyond it.
That idea, strange as it sounds, partially overlaps with a growing crisis in modern physics. Many high-energy physicists increasingly suspect that the fabric of space and time may not be fundamental reality after all. At the smallest scales of the universe—the Planck scale—the equations underlying modern physics appear to break down mathematically. This dilemma is pushing researchers to search for deeper structures beyond both conventional quantum theory and our ordinary understanding of the cosmos. Case in point: physicist John Wheeler of Princeton, who famously proposed “It from Bit,” the idea that physical reality may ultimately emerge from underlying information rather than matter itself.
“Space-time is doomed,” believes Hoffman. “It’s not just a cognitive scientist crying wolf about spacetime. The physicists themselves are saying we need to look beyond,” he continues. But if space-time is not fundamental reality, then what is?
Theoretical physicists have long struggled to reconcile quantum mechanics with gravity, and many of the equations of modern physics begin to break down at the Planck scale. So in 2013, some researchers began stepping outside of space-time itself. What they found were enormous geometric structures with strange properties—including giant diamond-shaped objects later dubbed amplituhedrons—that could predict particle interactions without relying on conventional notions of space and time at all.
These so-called “positive geometries” are exotic mathematical structures that attempt to derive the behavior of the physical universe directly from geometry itself rather than conventional space-time equations. They are the next clue outside of the space-time headset, Hoffman says. They may not yet represent the final truth, he quickly adds, but perhaps a crucial clue pointing toward it.
However, given the relatively young age of these “magical” structures in scientific research, Hoffman says: “Nobody yet knows what they really are.”
Still, the broader possibility that humans may not perceive reality directly is increasingly spreading to fields other than theoretical physics. Mona Sobhani, PhD—a cognitive neuroscientist and author who studies consciousness and anomalous experiences—says Hoffman’s theory at least aligns with one uncomfortable implication of evolution itself: Survival and truth may not be the same thing.
“Seems like a reasonable theory that is in line with the idea of evolution,” Sobhani says. “I think we are finding more scientists open to the idea, especially younger ones, although I’d say the mainstream explanations still sway toward the physicalist,” meaning theories that still treat matter and the physical universe as fundamental.
Critics are much more skeptical, however. While evolution may simplify perception, they argue, that doesn’t necessarily mean space-time itself is merely an interface or illusion. Some philosophers have also questioned whether Hoffman’s argument becomes self-defeating: If evolution shaped human cognition for survival rather than truth, why trust the conclusions produced by that cognition in the first place? A 2021 critique of Hoffman’s interface theory further argued that under more realistic environmental conditions, organisms disconnected from objective reality would actually be pushed closer to extinction rather than survival.
Still, such criticisms have not deterred a growing number of scientists from describing perception as a heavily filtered construction—a kind of shared hallucination even. Meanwhile, theorists such as Wheeler explored whether the physical world ultimately arises from deeper informational structures beneath space-time itself. Likewise, Stephen Wolfram, PhD, of the University of Illinois has argued that reality itself may emerge from hidden computational rules.
So, what if we ditched the headset altogether, directly dug into the deeper machinery of reality itself, and confronted the truth head-on?
“If you were smart enough, you could go into the supercomputer and toggle the millions of bits really, really quickly, and that would also be a way to play the game,” says Hoffman. Almost instantaneously, he circles back to evolution and what Darwinian payoffs have taught us, though not before wishing those who attempt it “good luck.”
For the interface of reality is essentially rigged against the searcher. Take Grand Theft Auto. The winner is rarely the player who stops to wonder why the Corvette is red, the Porsche black, or who designed Los Santos. The winner is the one who plays. For Hoffman, evolution clearly favors organisms that successfully navigate the game, not those that spend their time trying to understand the code running underneath it.
“Searchers will always lose to someone who can simply turn the steering wheel and hit the fake gas pedal inside the VR headset we call reality,” Hoffman says.
