"decades of research have shown meditation's effects to be highly unreliable, as James Austin, a neurologist and Zen Buddhist, points out in Zen and Brain. Yes, it can reduce stress, but, as it turns out, no more so than simply sitting still does. Meditation can even exacerbate depression, anxiety, and other negative emotions in certain people."
