I see a lot of anekdotes here on HN about meditation. But anekdotes are not science. I dislike the very close relation between meditation and spirituality that turns into fluffy bullshit. I distrust peoples self-reporting because it is extremely unreliable. The 'eight weeks to a better brain' sounds like any link-bait you see on the internet (' 6-pack in 12 days!'). Also, the results may be merely from the fact that these people spent ~30 minutes a day deliberately relaxing. What would happen if the control group would just lie on a couch for 30 minutes, doing nothing? None of that in the article.
