Study shows placebos can work even if you know it’s a placebo

Placebo Effect Benefits Patients Even When They Knowingly Take a Fake Pill

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.

Edit: Here’s the actual study. RolfAndreassen points out that its results may not actually be strong evidence for what is being claimed.
