5 min read

Nir Eyal returns to discuss his book Beyond Belief, drawing on six years of research to explain how beliefs act as a lens filtering perception, emotions, and actions. Grounded in peer-reviewed studies, he distinguishes beliefs from facts (objective truths) and faith (convictions without evidence), positioning beliefs as revisable convictions based on past experiences—or "priors." The brain processes 11 million bits of sensory data per second but consciously handles only 50 bits, relying on predictive processing to construct a simulated reality. This makes beliefs powerful: they literally alter what people see, as in the coffer illusion where urban dwellers perceive rectangles and rural ones circles.

Beliefs Shape Seeing, Feeling, and Doing

Beliefs influence biology and behavior beyond mysticism. Placebos work even when disclosed as inert, as Ted Kaptchuk's IBS study showed: labeled placebo pills matched leading drugs, with patients requesting refills. Branded painkillers outperform generics due to expectations. Prayer rituals yield health benefits—longer life, less depression—independent of supernatural faith; secular substitutes like "the universe" suffice, per a pain tolerance study where nonbelievers taught to pray outlasted controls in ice water.

Show Notes

Nir Eyal is an author, behavioral design expert, and investor.

What does it mean to truly hold a belief you endorse? Maybe some of what we believe isn’t true. But more interesting is how beliefs are formed, and how they can be reshaped. So how do you update your beliefs in a way that actually serves you, rather than holds you back?

Expect to learn why belief is so important and why they are just tools not truths, what’s wrong with the traditional view of behaviour change and motivation, why smart, disciplined people still quit when their beliefs weaken, how big of a problem limiting beliefs are, how to reframe rejection and failure, why rumination feels productive when it’s actually destructive, how to audit your beliefs and much more…
