Yea, makes sense.
Embracing the doubts, making the doubts part of the world.
It's unplausible if everyone in that world has the exact same opinion or version of facts or history or whatnot.

I will just change it if it's something that can easily be changed, otherwise I'll leave it be unless I really hate it. That's a good idea though, I should do that more often.

This is an approach that I really like because it incorporates a layer of realism (the real realism, not "real is brown" meme realism) that as a bonus is quite useful to produce plot hooks and various conveniences. After all, just because you as the worldbuilder know everything (or most things) about your world, that does not mean their in-universe people do. They are allowed to be wrong or incompletely informed, and unless they are an epic level lore gatherer, simple statistics say they are!

Mix this with approached for in-universe folklore and bam, realism explosion.
