Well, I checked PhD acceptance rates and they are much lower than I thought. I had honestly never met anyone who applied and failed to get a PhD place. I just assumed everyone got in, but they clearly don't so I got that wrong. Selection bias, obviously.
What do you disagree about in relation to autism and PDs? That diagnosis is based on patterns of symptoms is uncontroversial, isn't it? There are no biomarkers. Nobody thinks there's a single underlying cause for each disorder do they? Or are you talking about something else? I hope everyone reading this feels free to jump in evidence and arguments against what I have said.
I don't think it's just you. Responses on this thread are not what I expected! I've been on this site for a while, and normally people don't go after me like this, so I think it's the doctorates that are bugging people. Of course, it's reasonable to be suspicious of anonymous people online, and there are plenty of false threads on here, so that's fair enough, I suppose. Not much I can say in response though.
The idea that I should stfu because I didn't specialise in clinical seems unreasonable. I can't really follow that argument.
