Deconstructing the Placebo Effect and Finding the Meaning Response

TLDR

The current definition of the placebo effect conflates unrelated elements, obscuring its most intriguing aspects. The study aims to reframe the placebo effect by centering on the concept of meaning as a response in illness. The authors review multiple medical domains where meaning influences illness or healing and introduce the “meaning response” concept. They argue that redefining the placebo effect as a meaning response offers deeper insight into treatment mechanisms and could enhance patient well‑being.

Abstract

We provide a new perspective with which to understand what for a half century has been known as the "placebo effect." We argue that, as currently used, the concept includes much that has nothing to do with placebos, confusing the most interesting and important aspects of the phenomenon. We propose a new way to understand those aspects of medical care, plus a broad range of additional human experiences, by focusing on the idea of "meaning," to which people, when they are sick, often respond. We review several of the many areas in medicine in which meaning affects illness or healing and introduce the idea of the "meaning response." We suggest that use of this formulation, rather than the fixation on inert placebos, will probably lead to far greater insight into how treatment works and perhaps to real improvements in human well-being.
