Nir Eyal joins the podcast to explore one of the most foundational forces shaping our lives: belief. What if the way you see reality isn’t reality itself, but a simulation filtered through prior assumptions, expectations, and unconscious scripts? In this conversation, we unpack the difference between fact, faith, and belief—and why most of our suffering stems from confusing the three. Nir shares powerful research on predictive processing, placebo and nocebo effects, learned helplessness, and how our expectations literally alter what we see, feel, and experience in our bodies. From secular prayer and gratitude practices to Byron Katie’s turnaround method, this episode is a deep dive into how to move from limiting beliefs to liberating ones. If beliefs are tools, then the real question becomes: are the ones you’re using serving you?
