Reddit mentions of Doctoring the Mind: Why Psychiatric Treatments Fail

Okay, yes, it is possible to investigate meditation and apply various kinds of research design to that investigation. I haven't denied that. BTW you seem to have only linked to an image rather than an article. Without wanting to be dismissive, there is an instant problem with holding up RCTs and their grouped analyses up as the highest standard of evidence. It's too big a topic to explore here, and takes us way outside the subject of this thread, so I'll just link to a couple of texts:

Book length:
Article indicative of the literature: http://www.amazon.co.uk/Doctoring-Mind-psychiatric-treatments-fail/dp/0141023694http://ssir.org/articles/entry/rcts_not_all_that_glitters_is_gold

OF course I want good evidence. But the standards of rigour implied by the evidence-based medicine paradigm aren't actually always all that rigorous.

Meditation is currently advised as a treatment for a range of physical and mental health conditions on the basis that it has evidence based benefits. In some instances it has been suggested- from the evidence- that meditation may be better than antidepressants in the treatment of mental suffering.

These studies will not have involved Buddhist meditators- ie. people actively practicing meditation techniques learned and practiced within various Buddhist traditions and settings as part of a complete way of life- but only people with some "mindfulness" training.
