There are people who pay good money for homeopathic remedies, so I’m of the opinion that placebos are already being used.
Also, when I feel a cold coming on, I take one of those fizzy vitamin “makes-your-cold-shorter” remedies. It makes me feel better, even while I’m convinced it’s the placebo effect. It’s one of the flavors of my childhood, probably, chewable vitamin C. This must be the “theater” mentioned in the article.
If Big Pharma finds out how to make a lot of money from placebos, they would be everywhere. Whether that would be ethical is an open question.
