How do you determine a placebo is "known"? A basic pattern of thinking, when faced with contradictory information, is to assume some of it is false (whether or not you know specific reasons) and some of it is appropriate to rely on. People also rely on their sense of what everyone else is doing to figure out what to trust. So it's a false model if you assume that a disclosure means something is "known".

I don't honestly care and I'm not really interested in dissecting the finer points of whether someone knows whether they're getting a placebo or not. You brought up placebos, you tell me what you think about them.

I'm in the homeopathy-is-a-load-of-horseshit camp, not the gives-two-shits-about-placebos camp.
