I've tried looking up reliable information on cluster B personality disorders beyond "they exist, here is the list of symptoms according to the DSM-5" and there's just a bunch of pop psychology nonsense. Tried asking stuff here, people just flood the threads with the same pop psychology nonsense before the mods unceremoniously lock it. I don't know where to ask where I can get more reliable information. I don't know what keywords I need to put into Google Scholar or whatever to get it to spit out results with the information I'm looking for. Where am I supposed to go?

Edit: And yes, I've tried that Consensus AI thing. It's hot garbage.
