What if some of the things you believe most strongly aren’t actually facts—but tools you’re using to navigate a complicated world?
In this bittersweet final interview for Psychologists Off the Clock, Jill Stoddard welcomes back Nir Eyal, author of Beyond Belief: The Science-Backed Way to Stop Limiting Yourself and Achieve Extraordinary Results. Nir was Jill’s very first guest when she joined the podcast, making this conversation a fitting bookend to her time on POTC. Together, they explore how our beliefs shape motivation, perception, pain, relationships, and our ability to create lasting change.
Nir explains why beliefs are different from facts or faith, and why treating beliefs as tools rather than truths can give us more flexibility. He shares his personal story of struggling with his weight, how changing his beliefs helped him persist, and what his experience with Pain Reprocessing Therapy taught him about chronic pain.
You’ll hear why “seeing is believing” is only half the story, how our expectations can change our experience of pain and pleasure, why venting may reinforce the very beliefs that keep us stuck, and how expanding your portfolio of perspectives can create more freedom in relationships and everyday life.
Join Jill and Nir for a fascinating conversation about the power of belief—and a reminder that feeling bad isn’t necessarily bad. Sometimes, pain comes with purpose.
Listen and Learn:
- Why beliefs are neither facts nor faith, but flexible “working models” that help us navigate reality when the truth isn’t fully knowable
- How beliefs influence motivation, behavior, and persistence—and why believing you can succeed may be just as important as knowing what to do
- Nir’s personal weight-loss journey and how searching for the “one true” diet ultimately got in the way of persistence
- Why beliefs can be powerful tools even when we can’t prove that they are objectively true, and how choosing beliefs that serve us can change the way we respond to everyday challenges
- How attention shapes perception, why our brains rely on predictions and prior beliefs, and what the classic checkerboard illusion teaches us about seeing reality
- The relationship between beliefs, expectations, pain, and suffering—including what Nir learned from Pain Reprocessing Therapy and the surprising power of the brain to change the experience of chronic pain
- Why feeling bad isn’t necessarily bad, and how redefining discomfort as something that can accompany purpose may help us stop avoiding the experiences that matter
- How placebo and nocebo effects demonstrate the powerful role of expectations, and why beliefs can influence our experience through changes in behavior and biology
- Why venting can reinforce negative beliefs about other people, and how “getting it off your chest” may provide short-term relief while making us angrier in the long run
- How Inquiry-Based Stress Reduction can help us loosen rigid beliefs by developing a broader “portfolio” of possible perspectives rather than forcing ourselves to replace one belief with another
- Nir’s personal transformation in his relationship with his mother, and how questioning assumptions about other people can create more flexibility without requiring them to change
- How expanding our beliefs can create “wiggle room” to respond more flexibly, reconnect with our values, and take responsibility for our own contribution to difficult situations
