It's more like how you have to be careful with psychotherapists because they may try to sell you therapy you don't really need, and maybe your mate who's a surgeon points that out to you.

But thanks for illustrating my point so perfectly. All the people who think they're most rational on this topic are actually the least rational. Relying purely on mental shortcuts and social cues works right up until someone figures out how they can game you for profit, which is what's happening here (cry crisis = funding, grants, status, fame).

Yeah, but you would probably listen to a Neurologist about your lack of a foot problem if 99 out of 100 podiatrists told you 20 years ago that your perfectly healthy foot would fall off in 10 years if you didn't stop driving your car or you didn't pay them the money every day for the rest of your life.
