Right. And I do think that meticulous effort is invaluable because it heightens the cost of cognitive dissonance which can be important to reaching people on the sidelines.
But it makes you wonder if the debunking community should be a bit more intentional about intercepting whatever these psychological processes are that make people immune to evidence-based correction, and target those mechanisms the same meticulousness in patients of a debunk.
Although obviously I think the trouble with that is such a task would amount to helping steer such people into a fabric of social and cultural connectedness that's more valuable to them than the conspiracies are. Which seems a tall order. But maybe engineering an alternative psychological virus that crowds out the conspiracies in favor of something else is a more efficient option.
