The placebo effect has been shown to work even when the patient was told about it.
As in, the patient went in being fully informed about the placebo effect and it still worked.
And this weirdness also holds for the nocebo effect, where you get a negative/opposite effect that is out of character or excessive to the degree to which the treatment ought to fail or have negative repercussions.
