Despite a recent dubious claim that placebos don't require deception (critiqued here), placebos appear to function on the basis that a subject believes X will have effect Y. Without knowing too much detail, we say that the subject's mind/body will assist or attempt to achieve Y upon the perception that X causes Y.

Can a person, without self-deception [1] and with knowledge of the placebo effect, induce a placebo response? Or can a person knowledgeable of the placebo effect induce the same "reactions" that a placebo can normally be used to induce?

_{[1] self-deception. [for the purpose of this question,] any mental activity in the general category of suspending one's "participation" in the full body knowledge they normally possess.}
