Do stupid people have the potential to be the strongest Nen users?
Another thread talking about how Shizuku sucked up Pike's blood got me thinking, she was only able to do that because she believed blood wasn't a living thing. Similarily, Kurapika's Chain Jail theoretically performs the same way. As long as he truly believes someone is a Spider, his ability should work without killing him.
But that raises an interesting question. Since Nen restrictions are all based on personal interpretation, not reality, doesn't that give stupid people an advantage?
For instance, what if someone believed in something that clearly wasn't true, but it gave them an insane powerup simply because they believed it was?
Like, say there was a Nen savant who happened to have the mind of a child, and believed that everything was a plaything of some sort. People are plushies, guns and nukes are plastic toys, total childlike view of the world. It's not that they don't believe they can't get hurt, they just believe that they would only get hurt from these things as much as you or I believe we would get hurt from plushies or plastic toys.
In more technical Nen mechanics, this would either apply an area-wide Zetsu effect on everyone else, or greatly increase their Ren, making either everyone around them powerless, or making themselves indestructible.
Now, maybe this exact scenario doesn't hold up under scrutiny (I just thought of it on the fly) but would this general idea technically be a possibility?
