L.A. Paul on Vampires, Life Choices, and Transformation

Episode Summary

Executive Summary: Russ Roberts and L.A. Paul discuss transformative experiences—choices like becoming a vampire, having children, disability decisions, and religion—that radically change both what we know and who we become. Paul argues that standard expected-utility reasoning fails when evidence is too coarse, preferences shift after the choice, and first-person experience cannot be fully captured by description, testimony, or science.

Main Topics: Transformative experience as a decision problem (Priority: 5/5): Paul frames choices like becoming a vampire as irreversible, identity-changing decisions where the chooser cannot know what the outcome will be like until after committing. Limits of evidence, reference classes, and averages (Priority: 5/5): The conversation emphasizes that even good social-scientific evidence is too coarse-grained to predict an individual's response to life-changing experiences. Diachronic choice and conflicting selves (Priority: 5/5): A central issue is whether to follow present preferences or the preferences of the future self created by the transformative choice. First-person experience versus third-person calculation (Priority: 4/5): Both speakers debate the inadequacy of reducing rich human experiences to scalar measures like happiness or expected utility. Parenthood, disability, and religious transformation (Priority: 4/5): The discussion applies the framework to having children, cochlear implants and deaf culture, and religious identity, showing how these choices shape identity and values. Epistemic humility and alternative decision models (Priority: 4/5): Paul proposes recognizing the value of revelation, respecting what cannot be known in advance, and developing more nuanced models rather than pretending certainty.

Key Arguments: Transformative choices are hard because they are both epistemically transformative (you learn only by doing) and personally transformative (your values and preferences change). Expected utility and average outcomes are too blunt for major life decisions because they ignore the distribution of possible outcomes and individual variation. Reference-class reasoning can help in ordinary decisions, but for transformative choices it is often impossible to know which comparison group really applies to you. Testimony from people who have already undergone a transformative experience may be sincere, but it may not be actionable because their preferences and identities may no longer match yours. The best framework is epistemic humility: admit the limits of prediction and avoid imposing a false precision on life decisions. First-person experience has value that third-person, impersonal analysis misses; reducing life to a numeric score distorts human flourishing. Cultural norms, religion, and tradition historically helped resolve these choices, but modernity has expanded options and therefore increased uncertainty and angst.

Data Points: EconTalk archive episodes: 700+ - Roberts notes this is the first episode in the archive to discuss becoming a vampire. Interview date: February 11, 2020 - The episode introduction states the conversation date. Example of timing in diachronic choice: Noon to 5 p.m. - Paul uses a hypothetical in which the choice is made at noon and the vampire transformation occurs by 5 p.m. Childhood hearing example: Congenitally blind / congenitally deaf - Paul cites sensory transformation cases to illustrate epistemic revelation. Illustrative age comparison: 17, 40, 70 - Roberts references the play with three ages to show how identity changes over time.

Pivotal Quotes: "You don't know what it's like to live your life forward as a vampire." — L.A. Paul: Core statement of why transformative choices resist ordinary decision-making. "I think the value of revelation... we need to recognize what we can do and what we can't do, what we can know and what we can't know." — L.A. Paul: Paul's summary of her proposed response to transformative experience. "I don't want my children to be happy, I want them to have rich lives." — Russ Roberts: Roberts pushes back against happiness-as-scalar and emphasizes meaning and life quality.

Implications: Listeners should be skeptical of one-size-fits-all metrics for major life choices. For high-stakes decisions, humility, identity, first-person experience, and moral context matter as much as prediction and averages.
