Flip-flop
Ahh, no wonder the scientific community is the butt of so many jokes. I can't wait to read the articles a year from now which state "oops, we were wrong... brain training DOES work".
This reminds me of all their other flip-floped "findings", like the evils/merits of eggs, red wine, beer, chocolate, vitamin pills, coffee, carbs, yadda yadda yadda. Next, please.
