Sorry. I think my previous post may have been unclear. I was referring to the effectiveness of unblinded placebos, not expensive placebos in my previous post.

I'm assuming that the study to which Paul B. is referring is the following: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0015591#pone-0015591-g002 Full reference is: Kaptchuk, T. J., Friedlander, E., Kelley, J. M., Sanchez, M. N., Kokkotou, E., Singer, J. P., ... & Lembo, A. J. (2010). Placebos without deception: A randomized controlled trial in irritable bowel syndrome. PloS one, 5(12), e15591. It will be interesting (and important) to not only replicate this finding, but to examine its potential generalizability and boundary conditions as applied to other medical and psychological conditions.

I seem to recall another study that showed placebos to be effective even when the subjects knew that the drug was a placebo. That's been my (warning:anecdote) personal experience; I take some drugs where I've read the studies that show them to be pharmacologically ineffective.
