Try to focus on the main point in the abstract: if delusion X is low-status and rejected by experts and high-status people (even if it might be fairly widespread among the common folk), while delusion Y is instead accepted by them, so much that by asserting non-Y you risk coming off as a crackpot, should we be more worried about X or Y, in terms of both the idealistic pursuit of truth and the practical problems that follow?
Y, of course. Perhaps I should have started out by saying that while I agree that what you say is possible, I don’t know if it describes the real world. Your assertion was that there are many high status delusions, but without evidence of that, all I can say is that I agree that supposed experts are not guaranteed to be correct on every point, and that it is extremely possible that they will reinforce delusions within their community.
Words written on paper count very well when we have a decent reason to expect that they are not utterly fabricated. The opposite is true in this case. Unless you claim this particular experiment is somehow distinct from all the other parts of the Bible which never happened.
