Placebos are sometimes used in research in order to demonstrate the effects of participant expectations or beliefs on the outcome of behavior.
true or false?

True

Explanation:

Placebos are treatments that have no pharmacological properties and therefore do not act directly on diseases.  Placebo is not just a medicine, it can be any medical procedure, including surgeries and anesthesia.

Used mainly in research control groups, they are critical for assessing the effects of a given drug.  When we use placebos in experiments, we expect that the group using it will not show any clinical improvement. The group that is using the actual drug should present a substantial improvement, thus representing the therapeutic efficacy of a new drug.

It is very important that the patient who is using a placebo does not know that this "drug" will not lead to a cure.  Therefore, he must believe that it is a medicine or therapy with proven curative effects.
