Study shows placebos can work even if you know it’s a placebo
This is a little bit disturbing. (A kind of belief in belief, perhaps? Like, “I know a placebo is where you take a fake pill but it makes you feel better anyway if you believe it’s real medicine, so I’d better believe this is real medicine!”)
Though it’s too bad they (apparently) didn’t have a third group who received a placebo that they didn’t know was a placebo, to compare the effect size.
