This page has been split from Placebo due to the length of that page. In doing this, I have made a few changes, such as putting proper inline citations with pubmed links, and in some cases online links to actual source papers. I have also reorganized it in various ways to make it read with greater continuity, notably I have put the history section down a bit and raised the methodological issues to the start.-- LittleHow ( talk) 09:46, 9 January 2009 (UTC) reply

There's a recent article from Wired that has a lot of information that could be added to the article:

• Steve Silberman (August 24, 2009). "Placebos Are Getting More Effective. Drugmakers Are Desperate to Know Why". Wired magazine.
