Placebo effect is a well-known phenomenon attracting the interest of both physicians and non-physicians. The number of evidence-based studies examining the magnitude of placebo effects and the mechanisms responsible for placebo effects has steadily increased over recent decades. Currently available evidence shows that many diseases such as heart failure, gastric ulcer, Crohn-disease, asthma, Parkinson-disease, depression and the common cold respond well to placebo therapies. In spite of all of these facts the conventional understanding of placebo effect and of the role of placebo effect in medical treatment is based on confused and contradictory ideas. The research program focuses primarily on these questions, and the ethical considerations raised by them.
