The placebo response is a real psychological, physiological, and ultimately statistical phenomenon that can be a powerful therapeutic tool in the world of medicine, especially when it comes to chronic pain conditions. For a drug to be approved, its developers must be able to demonstrate that it is significantly more effective compared to a placebo. Unfortunately, placebo response rates and effect sizes have increased considerably over the last few decades. Even certain well-established drugs can no longer surpass placebos in modern trials.
