Why do some people actually experience measureable effects when given a placebo(fake drugs) versus the actual drug? Is is the power of suggestion, belief, or something else?
Few examples in which placebo looks effective even if it isn't (Wikipedia):
- The condition, for example, common cold heals on its own in participants who received a real drug and in those who receieved a placebo.
- In psychological and other conditions in which the participants are asked only how they feel after the treatment, some of them may just think that they feel better.
- Sometimes neither the real drug nor the placebo work, but the condition has a naturally fluctuating course, so it looks that they both work.
