Placebo response and “Mindsets”

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.”

Suggestible You

In his book, ‘Suggestible You: The Curious Science of Your Brain’s Ability to Deceive, Transform, and Heal’ author Erik Vance explores placebos, hypnosis, and how beliefs influence bodily responses to pain.

“Placebos and beliefs generally is so much a part of our lives,” he tells Kishore Hari on a recent episode of the Inquiring Minds podcast. “It has an amazing power to change our bodies.”

Branding Research Shows Placebo Effect on Consumers

“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.”

When you know you’re taking a placebo …

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.

Arthritis medication: placebo beats supplements

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.

Placebo Effect Works for Heart Procedures, Too

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”

Energy drinks? Yep – it’s the Placebo Effect!

‘Cognitive enhancers’? Oh, do us a favour. Highly hyped and highly price energy drinks like Red Bull are all about the sugar and the caffeine, that’s all. Lots of sugar and caffeine. So why pay the premium, the enormous mark-up? It’s marketing, probably one of the shiniest examples of the placebo effect in marketing. Some science on this over here.

On Placebos and Depression Drugs

We note an interesting ‘counter narrative’ emerging – that is, scepticism about the commonly held view that drug treatments designed for mood disorders such as depression often engage the Placebo Effect. In this counter-narrative,

“Drug trials don’t show much in the way of classic placebo effects. The rise in placebo responses over the years is more likely due to the supportive factors in drug trials…and increasing problems with enrollment.”

The new finding—no upward trend in placebo responses—is unexpected and certain to be contested. Meanwhile, it stands as a rebuke to a popular narrative. By that account, drug effects had been hyped, expectations soared, and the inflated hopes were reflected in rising placebo response rates.”

This is fine, except the counter-narrative also resonates with challenges about the efficacy of conventional ‘gold-standard’ ‘blind’ ‘placebo controlled’ drug trials, where it has been shown that trials funded by drug companies (who by definition have a vested interest in their outcome) are 30% more likely to return ‘favourable’ results than trials which are not funded in this way. The ‘placebo effect’ might be the design and execution of the trial itself, not the actual function and efficacy of the placebo …!
