I’d say that near-universal falling fertility rates already below replacement in the post-British global system, combined with continued net integration of unaligned countries into that system, implies that not taking ideas seriously isn’t healthy. Taking new ideas seriously is high-variance, with more downside when few people are doing it (so there’s less error-correction), so one might recommend conservatism if things basically seem to be going well. But in some key respects they don’t.
