What is the Placebo Effect?
The placebo effect is the improvement of a patient’s health when using placebos. A placebo is a medicine prescribed for the psychological benefit of a patient. During a clinical trial, some patients receive the medicine, but others receive a placebo. All patients believe that they are receiving the real medicine, which makes them have a positive attitude. As a result, some of them are more cautious of their diet, doing exercise, or other factors like quitting smoking during the clinical trial. Doctors use the placebo effect to test medicine and to see if it actually works, or it is just the mental attitude and food/hygiene changes that occur to the patients during a clinical trial. Some reasons why people volunteer for the clinical trials is because in the past they have performed these experiments on people in jail, and they have said that if they volunteer, they will be let out of jail.
