Placebos work even when you know they don't contain medicine

If it works, it seems very humane to prescribe placebos rather than prescribing things that do permanent damage or have high risk of doing so. For instance, it seems reasonable to try a placebo before a SSRI, since placebos have less risk of triggering an avoidable suicide. If they don’t work you can move on to Prozac afterwards. Why would that bother you? What’s wrong with “first, do no harm”?

Oh, I get it now… we must not consort with witches.

EDIT: re-reading the above it seems harsh. Sorry about that, but I haven’t time to frame it better - gotta go fix some stuff.
