Placebos work even when the patient knows it's a placebo ?

Why should it be the case that being told it’s a placebo eliminates the effect? This would require that the placebo effect is due to a patient’s conscious knowledge, which seems rather dubious.

That should probably say ‘solely due to’—I don’t doubt that it does have a role to play, but it needn’t be the sole determining factor.
