I think the problem is that the more complex the narrative, the less appealing it is. All narratives are fact-based, what makes the "scientific method" narrative unappealing is that it is open-ended. There is a narrative of "scientism" which is that science has an answer for everything, and that is appealing. But if someone who subscribes to "scientism" asks a follower of the "scientific method" for the "scientific answer" and the answer is "you see, things are really complex, and we don't have all the facts, but...", eyes start rolling.

Sort of like students wanting you to tell them the answer to their homework but not being really interested in an explanation.
