A refreshingly sober view on important issues in mental health science that I think about a lot... I'm not as pessimistic/nihilistic as I come across sometimes, but I do worry deeply that we are often not meeting the challenges where they are.
Putting the two together: The mushy imprecision of our methods leaves room for almost any theory to be substantiated and for any 'mechanism' to find some kind of operational instantiation, but not really. Not at all, in fact, from where I stand. It's all so impossibly noisy and imprecise.
