Ben Goldacre on the Placebo Effect

This is clear, concise and sensible, and worth spending the time watching.

He doesn't mention the nocebo effect which is just as valid and powerful. If you believe you're being harmed by something, the nocebo effect makes it much more likely that you really will be harmed. I feel sure it works in exactly the same way as the placebo effect, though I've no idea whether any research has been done.
