Sacred Values: How Our Deepest Convictions Lead Us Astray | Dr. Steven Sloman – EP 715

What if many of our most heated debates and divisions aren't really about facts or outcomes, but about clinging to sacred values that feel absolute and non-negotiable?

In this eye-opening episode of Passion Struck, cognitive scientist Dr. Steven Sloman joins John R. Miles to unpack his groundbreaking book, The Cost of Conviction: How Our Deepest Values Lead Us Astray (MIT Press, May 2025).

Drawing on decades of research into how we think individually and collectively, Steven reveals why we often prioritize "right vs. wrong" sacred values over practical consequences—leading to oversimplification, outrage, polarization, and even extremism. From the illusion of explanatory depth (where we overestimate our understanding) to taboo and tragic trade-offs, this conversation explores how sacred values unite communities, define identities, and drive history, yet also create barriers to dialogue on issues such as abortion, immigration, climate change, and political conflict.

John and Steven dive into real-world examples: the rise of zealotry from ancient Judea to modern times, the shifting values among young men, the role of belonging in group identity, and why reframing conversations around consequences (rather than slogans) offers a path to better decisions, adversarial cooperation, and reduced division. At its heart, this episode is a call to question certainty, respect expertise, and balance conviction with humility—reminding us that true wisdom lies in thinking harder about outcomes, even when sacred values feel compelling.
