Here’s a fascinating story from a writer at the Smithsonian who experienced that the placebo effect is engaged even if you KNOW you’re taking a sugar pill.
“I was in grad school training as a psychotherapist,” (Kelley) told me once, “and I came across a study arguing that antidepressants work just as well as psychotherapy. I didn’t mind that so much, because I like psychotherapy and see its value. But later I found another study showing that antidepressants actually work no better than placebos, and that definitely bothered me. Did this mean that psychotherapy was nothing but a placebo? It took me quite a while to consider the reverse, that placebo is a form of psychotherapy. It’s a psychological mechanism that can be used to help people self-heal. That’s when I knew I wanted to learn more.”
It seems that here at Universal Placebos we’re selling ‘open label’ placebos, that is, placebos explicitly labeled as placebos. It’s so nice that science is catching up!
In his research, which includes a wonderful ‘one person experiment’ designed to use placebos in tackling writer’s block, the author interviews Kathryn Tayo Hall, a geneticist at Brigham and Women’s Hospital, and ‘sheepishly’ admits to the fact that placebos worked for him.
“Brilliant,” she said, and showed me a box of homeopathic pills she takes to help with pain in her arm from an old injury. “My placebo. The only thing that helps.”
“I don’t have to believe in you,” (the author says directly to his placebo pills), “because you’re going to work anyway.”
A recent meta-study in the World Journal of Gastroenterology (March 28 2017) – Systematic review: The placebo effect of psychological interventions in the treatment of irritable bowel syndrome
Aim – “To determine the placebo response rate associated with different types of placebo interventions used in psychological intervention studies for irritable bowel syndrome.” (Six studies, with a total of 555 patients met the inclusion criteria.)
… and the placebo effect, unsurprisingly, figures significantly:
“Contrary to our expectations, the PRR (Placebo Response Rate) in studies on psychological interventions was comparable to that in studies on pharmacological, dietary and alternative medical interventions.”

A new study published in Brain indicates that successful treatment for insomnia may not actually require complicated neurofeedback (direct training of brain functions).
Rather, it appears patients who simply believe they’re getting neurofeedback training appear to get the same benefits.

The research effort on the placebo effect deepens and widens.
“In a report published online Feb. 15 in The BMJ, researchers at Stanford call for more health care providers to place emphasis on the importance of individual mindsets and social context in healing … (and) to develop more studies that measure the physical effects of these psychosocial elements to understand and quantify patients’ subjective experiences of expectations, connection and trust.”
“We have long been mystified by the placebo effect,” Crum said. “But the placebo effect isn’t some mysterious response to a sugar pill. It is the robust and measurable effect of three components: the body’s natural ability to heal, the patient mindset and the social context. When we start to see the placebo effect for what it really is, we can stop discounting it as medically superfluous and can work to deliberately harness its underlying components to improve health care.”

“I was just amazed that you could change what price you were going to launch a product at, and you could change what brand it was, and people would have dramatically different impressions of that product. And they would tell you incredibly different things about the product: they thought it was made of different materials, they thought it weighed more or it weighed less. Really out-there stuff that, at the time, we joked about but we couldn’t explain.”

This question/comment/assumption comes up a lot when we talk to people about placebos and the placebo effect. ‘It works’ (is the assumption) ‘if people believe it’s something else’ …
Like the ‘real’ thing, perhaps …? We’ve posted on this before, and it seems the research is becoming more robust and rigorous.

Many people take glucosamine and chondroitin supplements for arthritis pain, but a controlled trial has found no evidence that the combination works. In fact, in this study, the placebo worked better.
Spanish researchers randomized 164 men and women with knee osteoarthritis to take a single daily dose of 1,500 milligrams of glucosamine and 1,200 of chondroitin, or an identical looking placebo. The study is in Arthritis & Rheumatology.

New research has shown that patient’s envisioning and expecting positive results from major surgery, including open heart surgery, will over time actually recover and heal more effectively.
“Optimizing patients’ expectations pre-surgery helps to improve outcome 6 months after treatment. This implies that making use of placebo mechanisms has the potential to improve long-term outcome of highly invasive medical interventions”
Placebo treatments seem to have an effect on pets … but is the effect on the pets themselves, or ‘second hand’ through a placebo effect on pet owners? Find out here.
NBC News reports:
“The study included about 300 kids aged 8 to 17, enrolled at 31 centers. They had 11 migraines on average in the month before the study began and were randomly assigned to take either of the drugs or placebo pills daily for six months. Migraine frequency in the study’s last month was compared with what kids experienced before the study. At least half of kids in each group achieved the study goal, reducing migraine frequency by half.”
