From imagination to neuroimage: An anthropological analysis on the rationality of the placebo effect in clinical trials

Abstract

The placebo effect is an obligatory passage point to understand rationality in randomized clinical trials. From the perspective of science and technology studies, this paper analyzes how the notion of the placebo effect has been used by science in the production of biosocial borders. Thus, it will pay attention to the phenomena considered caused by imagination, and we will analyze the consequences of new methodologies that have recognized other potentialities of this effect but tend to favor biological markers. The central argument is that the epistemological dispute hides the multiple existences of the placebo effect to be recognized due to the different scientific practices to which it confers rationality.
