What if anxiety, bad habits, and even curiosity can all be explained by a single mathematical principle? What if your brain isn’t processing information—it’s actively constructing fantasies to explain the world?
Professor Karl Friston is the most cited neuroscientist alive. His Free Energy Principle attempts something audacious: to explain what all living things, from cells to humans to future AI, are fundamentally trying to do. His work underpins modern theories of prediction, perception, consciousness, and how the brain actually works. But beyond the mathematics lies something deeply human—a framework for understanding why we feel anxious, why we can’t break bad habits, what makes us curious, and how our minds construct reality moment by moment. His ideas are being explored not just in neuroscience, but across psychology, biology, robotics, and AI development. Now Chief Scientist at Verses AI, Karl is building the next generation of agentic artificial intelligence based on these same principles.
