Problem as I see it, with studies in general, is that there is no guarantee that what was reported matches reality. Who paid for the study, what were the biases and objectives of those running the study, what data was omitted, what data was distorted, what powerful financial interests were involved, etc etc?

I also question anything that medicalizes mental health or tries to make it a measurable scientific enterprise. That sort of thinking is what led to the horrors of the DSM, biological psychiatry (it's a chemical imbalance in your brain, take this pill), and psych drugs.

Seems like our culture is obsessed with science. It's a bit like a religion with its own zealots and scary dogma.
