Intelligent people tend to be more rule abiding in general
As an aside, do you have a source for this? A quick search didn’t turn up anything useful.
My intuition would be the opposite: if people are acting meta-rationally, then less intelligent people should be more rule-abiding because they know they’re not smart enough to figure out when exceptions are worth it. But I don’t have anything to back that up.
I believe [this](https://www.lesswrong.com/posts/ftbtZy9dBmYC5StQz/lesswrong-v2-0-anti-kibitzer-hides-comment-authors-and-vote) is what you are referring to. I have the same preference as you and I use Marcello’s script.
