A while ago I mentioned how I'd set up some regexes in my browser to alert me to certain suspicious words that might be indicative of weak points in arguments.

I still have this running. It didn't have the intended effect, but it is still slightly more useful than it is annoying. I keep on meaning to write a more sophisticated regex that can somehow distinguish the intended context of "rather" from unintended contexts. Natural language is annoying and irregular, etc., etc.

Just lately, I've been wondering if I could do this with more elaborate patterns of language. It's recently come to my attention that expressions of the form "in saying [X] (s)he is [Y]" is often indicative of sketchy value-judgement attribution. It's also very easy to capture with a regex. It's gone in the list.

So, my question: what patterns of language are (a) indicative of sloppy thinking, weak arguments, etc., and (b) reliably captured by a regex?

(In the back of my mind, I am imagining some sort of sanity-equivalent of a spelling and grammar check that you can apply to something you've just written, or something you're about to read. This is probably one of those projects I will start and then abandon, but for the time being it's fun to think about.)
