As a programmer and former EEG tech, all I can do is nod quietly. They could be way more scientific about their medication selection if they wanted to be [1][2] but most psychiatrists are overconfident in their own judgement.
There's a difference between "how about we approach it more appropriately" and kyro's "we shouldn't use this at all until we have a near-complete understanding".
I never advocated discontinuing the use of medications. In fact, I acknowledged their efficacy. I'm all for treating the people that cannot function otherwise -- they may have no other choice. I think for millions of others, there are other choices that are not being adequately pursued or encouraged.
