Brain Chain query

Brain Chain is supposed to be a sliding scale of intelligence in works right? In practice, I dunno if that works because i don't see what purpose pointing out any instance of intelligence in a work serves. The page is organized in a confusing way too.

Just seems like a more specific version of the Intelligence Tropes index. Don't see a reason to keep it

I have recently noticed some troper have been copying examples from other Intelligence Tropes to that page, which is spurious.
