It occurred to me that another way to try to move someone on complicated category 3 disagreements might be to put together a well-constructed survey of a population that the person is inclined to defer to. This approach is definitely still tricky: you’d have to convince the person that the relevant population was provided with the strongest arguments for that person’s view in addition to your counterarguments, and that the individuals surveyed were thinking about it reasonably hard. But if done well, it could be pretty powerful.
