Homeocracy 3

The previous post of this series analyzed the results of the 1994 Pediatrics paper purporting to show a statistically significant effect of homeopathic preparations on acute childhood diarrhea in a population in Nicaragua. That clinical trial followed a pilot study that also had shown a small but statistically significant effect of homeopathic remedies.

A moment here for explanation as to why I am going through these old studies. Reports like the four or five in this series made headlines. They are also so well cloaked in manipulated data and overdrawn conclusions that press and even academicians accept their conclusions – and even overdraw more. This is still going on.

Over the past thirty years some of us informally and gradually developed semi-systematic ways of analyzing these increasingly scientific-appearing claims of sectarians (sCAMmers.) Errors, inconsistencies and falsifications we recognize now were not so obvious decades ago. SCAMmers developed imaginatively new methods as their fields progressed. We in the science-based or knowledge based medicine field have been trailing along, detecting their tricks and twists as they developed, and like street sweepers behind horses, picking up their excrement (metaphor to force attention.)  Yesterday’s lucid post on the latest acupuncture study by Steve Novella exemplifies this expertise (no offense intended.)

Being Right Versus Being Influential

On May 9th I had the pleasure of lecturing to an audience of critical thinkers at the NYC Skeptics meeting. The topic of discussion was pseudoscience on the Internet – and I spent about 50 minutes talking about all the misleading health information and websites available to (and frequented by) patients. The common denominator for most of these well-intentioned but misguided efforts is a fundamental lack of understanding of the scientific method, and the myriad ways that humans can fool ourselves into perceiving a cause and effect relationship between unrelated phenomena.

But most importantly, we had the chance to touch upon a theme that has been troubling me greatly over the past couple of years: the rise in influence of those untrained in science on matters of medicine. I have been astonished by the ability of “thought leaders” like Jenny McCarthy to gain a broad platform of influence (i.e. Oprah Winfrey’s TV network) despite her obviously flawed beliefs about the pathophysiology of autism. Why is it so hard to find a medical voice of reason in mainstream media?

The answer is probably related to two issues: first, good science makes bad television, and second, physicians are going about PR and communications in the wrong way. We are taught to put emotions aside as we carefully weigh evidence to get to the bottom of things. But we are not taught to reinfuse the subject with emotion once we’ve come to an impartial consensus. Instead, we tend to bicker about statistical analyses, and alienate John Q. Public with what appears to him as academic minutiae and hair-splitting.

I’m not sure what we can or should offer in place of our “business as usual” behavior – but I’ve noticed that being right isn’t the same as being influential. I wonder how we can better advance the cause of science (for the sake of public health at a minimum) to an audience drawn more to passion than to substance?

I would really enjoy your input, dear readers of Science Based Medicine, because I’m at a loss as to what we should do next to reach people in our current culture, and with new communications platforms. What would you recommend?
