Built to Stay: How Leaving Mormonism Feels Impossible

Why Leaving Mormonism Is So Hard — The Psychology of Identity, Belonging, Cognitive Dissonance, and Sunk Costs Intelligent, thoughtful people stay in the Mormon church long after encountering evidence that should have sent them running. This is not a failure of intelligence. It's how belief architecture works.  This research-dense episode applies the psychology of belief directly to LDS institutional structure. Paul Harris on why children inherit belief before they can evaluate it — by the time questioning is possible, you're not in neutral territory, you're defending the foundations of your self. Robert Cialdini on commitment and consistency — temple covenants, mission service, and decades of public testimony-bearing create enormous psychological resistance to contradictory information. Leon Festinger on cognitive dissonance. Ziva Kunda on motivated reasoning. Dan Kahan on identity-protective cognition: when belief is identity-constitutive, threatening the belief feels like threatening the self. The sunk cost architecture of Mormonism is not accidental — missions, tithing, callings, and family relationships are all deliberately built inside the institution. If the people you love haven't left, this episode is why. In this episode: Paul Harris on childhood belief inheritance and why questioning feels like self-betrayal; Robert Cialdini's commitment and consistency principle applied to temple covenants and missionary service; Leon Festinger's cognitive dissonance theory and how the church engineers it; Ziva Kunda's motivated reasoning research; Dan Kahan's identity-protective cognition framework; the sunk cost architecture of Mormonism — tithing, callings, missions, temple marriage — and why leaving feels financially, socially, and existentially catastrophic. Support the show: buymeacoffee.com/postmormonpostmortemAd-free listening from $2/month: patreon.com/postmormonpostmortemTikTok & Instagram: @postmormonpostmortempostmormonpostmortem.comNew episodes every Sunday at 9 AM — just in time for sacrament meeting.
