Let's be explicit here - your suggestion is that people like me should not be here. I'm a lawyer, and my mathematics education ended at Intro to Statistics and Advanced Theoretical Calculus. I'm interested in the cognitive bias and empiricism stuff (raising the sanity line), not AI. I've read most of the core posts of LW, but haven't gone through most of the sequences in any rigorous way (i.e. read them in order).

I agree that there seem to be a number of low quality posts in discussion recently (In particular, Rationally Irrational should not be in Main). But people willing to ignore the local social norms will ignore them however we choose to enforce them. By contrast, I've had several ideas for posts (in Discussion) that I don't post, but I don't think it meets the community's expected quality standard.

Raising the standard for membership in the community will exclude me or people like me. That will improve the quality of technical discussion, at the cost of the "raising the sanity line" mission. That's not what I want.
