“Conventional medical wisdom has long held that placebo effects depend on patients’ belief they are getting pharmacologically active medication. A paper published in the journal Pain is the first to demonstrate that patients who knowingly took a placebo in conjunction with traditional treatment for lower back pain saw more improvement than those given traditional treatment alone.” https://www.sciencedaily.com/releases/2016/10/161014214919.htm
This RLE is quite interesting as it show that not only is there a placebo effect, there is a placebo effect even when patients know that are getting a placebo instead of actual medicine.
One could argue that some medical perspectives and practices are not focused enough on how psychology affects health and medical treatment.
Placebos are often used in double-blind experiments done to check the effectiveness of medicine. The research in this case shows a much deeper understand of placebos because a researcher asked what if patients knew they were getting a placebo.
