Question

Many years ago, some doctors administered medication to the patients themselves, as opposed to using a pharmacist. One curious yet unethical doctor decided to start giving all his patients sugar pills in place of the actual medication. To his surprise, many of his patients actually had their symptoms vanish despite not getting the actual medication. Explain how this might happen.

Answer 1

An example of placebo effect. This effect can be caused by patients' belief that the treatment must help them, usually they were told that they take strong treatment and there is no way that they won't recover. Even though it's going out of moral and science principles, there are many occurences in which placebo really worked.
