Abstract
An attempt to reconceptualize placebo phenomenon. Placebo isn't only a glucose pill, and a glucose pill is not always a placebo. The concept of placebo in Psychology comes from Medicine and Pharmacology, and its theoretical conception, as well its application has been biased by its origins. We believe that placebo is not an unitary concept: Placebo can have different meanings, depending on the scientific discipline in which it is used. We defend the existence of placebo in Psychology, Medicine, and other sciences, but we consider that, what traditionally has been conceived as placebo in psychotherapy rests on unknowledge. We attempt to re-conceptualize this phenomenon in the setting of scientific theories.
