What if the Placebo Effect Isn’t a Trick?
New research is zeroing in on a biochemical basis for the placebo effect — possibly opening a Pandora’s box for Western medicine.

The Chain of Office of the Dutch city of Leiden is a broad and colorful ceremonial necklace that, draped around the shoulders of Mayor Henri Lenferink, lends a magisterial air to official proceedings in this ancient university town. But whatever gravitas it provided Lenferink as he welcomed a group of researchers to his city, he was quick to undercut it. “I am just a humble historian,” he told the 300 members of the Society for Interdisciplinary Placebo Studies who had gathered in Leiden’s ornate municipal concert hall, “so I don’t know anything about your topic.” He was being a little disingenuous. He knew enough about the topic that these psychologists and neuroscientists and physicians and anthropologists and philosophers had come to his city to talk about — the placebo effect, the phenomenon whereby suffering people get better from treatments that have no discernible reason to work — to call it “fake medicine,” and to add that it probably works because “people like to be cheated.” He took a beat. “But in the end, I believe that honesty will prevail.”/.../
