I don't mind using short titles; your point about easy searching and linking makes sense I think.

I don't want the thing I was envisioning to be called a "study guide", though. Because I want the individual "study guide"-like pages to serve not only as a guide for newcomers but also as a summary of what we've produced so far as a community, and where the gaps in our analysis are. Your other suggestions don't really unite the purposes either. We could just do e.g. "Heuristics and biases, conversational style", but that doesn't indicate purpose the way "study guide" does and I don't much like the way it sounds. Maybe it would help if I understood what purpose or use-case you have in mind for the NPOV style articles, as a contrast class.
