If you read some self-blinding studies for things like modafinil et al. you'll see this isn't always the case. (They get surprised when they find out at the end of the experiment cycle that a particular pill on a particular day was just a sugar pill.) Placebo effects are weird. In any case while the plural of anecdotes is not "data" I still think anecdotes are valuable.
