I'm not aware of any research that says a placebo won't help a "non-believer" - can you cite a study? Given the study I linked where they were deliberately handed inert pills and told that they were an inert placebo, and they still worked, I actually strongly doubt your claim.

And given the research I linked, why in the world wouldn't you believe in them? They do rationally work.

A placebo will help if you think the pill you're taking will help. This may be because you think it's a non-placebo pill that'd help even if you didn't know you were taking it, or because you know it's a placebo but think placebos work. If you were given a placebo pill, told it was just a candy and given no indication it might help anything, it wouldn't do anything because it's just sugar. Likewise if you're given a placebo, know it's a placebo, and are convince on al levels that there is no chance of it working.

Right. So find someone who will tell you it's a placebo, and read up on the research that says it does work. It'd be irrational to believe that they don't work, given the volume of research out there.

facepalms Did you even read any other post in this thread?

Yes, but you have to BELIEVE the placebos will help.

Quite a few of them. You're being vague enough that I can only play with the analogies you give me. You gave me the analogy of a placebo not working if you don't believe in it; I pointed out that disbelief in placebos is rather irrational.

Trying to figure out if it's rational or not, and if so HOW it's rational so I can convince my brain of it, is exactly what the entire discussion is about starting from the first post here: http://lesswrong.com/lw/7fo/open_thread_september_2011/4r8q

Can anyone think of a better thing to have said here?

A single study is not sufficient grounds to believe in something, especially a proposition as complicated as "placebos work" (it may not sound complicated expressed in this way, but if you taboo the words 'placebo' and 'work' you'll see that there is a lot of machinery in there).

See previous discussion here and note my remarks, I recommend reading the linked articles.

Given Armok is looking for a psychological solution, this still seems relevant. There have been a number of interesting studies on placebo effects; whether it's the actual pill or just priming, it does have a well document and noted beneficial effect, and it seemed relevant to Armok's situation.
