Question

Joanie is in a research study in which she is told that a powerful new drug will dramatically increase her memory abilities. she is then administered the drug, which is in fact a placebo. how will joanie do on a memory test after taking the drug?

Answer 1

She will likely do better, because she thinks she has fantastic memorization powers.  My parents once put a dish of oregano on my nightstand and told me it would make me sleep better, it did simply because I thought it would, even though oregano has no soporific qualities.
