Triumph of the Heart, as its name does not suggest, is about science. The book’s author, Jie Jack Li, is a medicinal chemist who meticulously reviews the history relevant to the discovery of lipid-lowering drugs. He spares no details, even recounting the amusing quarrels and quirks of the scientists engaged in the “apocryphal showdowns” leading to the manufacture of cholesterol in a laboratory.
The personalities of the various scientists and Nobel laureates described in the book are highly entertaining. From beating one another with umbrellas, to insisting on wearing blue clothing only, to egos so large and unappealing as to empty an entire academic center of all its promising young recruits, one has the distinct impression that brilliance does not go hand-in-hand with grace.
That being said, each of these scientists did seem to share a common approach to research: carefully testing hypotheses, repeating peer study results to confirm them, and patiently exploring complex biochemical pathways over periods of decades. The physicians, physicists, and chemists showed an incredible ability to doggedly pursue answers to specific questions – understanding that the results might influence human health. But even more importantly, they were each willing to invest their careers in analysis that may never lead to anything more than a dead end. In fact, the book is full of examples of great ideas, developed over decades, that did not lead to a marketable drug. In some cases the research was halted due to lack of efficacy, in others political forces or personal whims influenced the course.
In the interests of fairness and intellectual honesty, I’ve forced myself to read a lot of really bad books. The True Believer tells me his guru’s book is the Real Stuff. He tells me I have a closed mind and won’t look at anything outside establishment dogma, and if I only read the book and understood Dr. Quack’s evidence and arguments, I would be a True Believer too. I have tried, really I have. I’ve given the Dr. Quacks every chance to convert me, and I’ve hoped to learn something new, but I’m always disappointed. I’ve come to the point that I feel like I’m reading the same book over and over: it is always a mixture of real science, pseudoscience, and speculation, based on cherry-picked evidence and argued with the same logical fallacies.
I recently got hooked into reading another one by a correspondent who had called me an “ignorant relic” for writing a “grossly ignorant article” about alternative medicine. I suggested he read R. Barker Bausell’s book Snake Oil Science and a couple of others, which he promised to do. Then he said, “If I am willing to buy three books that you have suggested and read them and you are not willing to read what I have suggested, then that pretty much says all that needs to be said.”
I was willing, even though the very title of the book suggested that its message was incompatible with the scientific evidence as I know it: How to Prevent and Treat Cancer with Natural Medicine. The authors are big names in naturopathic and herbal medicine: Michael Murray, Tim Birdsall, Joseph Pizzorno, and Paul Riley. It’s nowhere near as bad as some of the bad books I’ve read, but it is a good example of the genre and I’ll use it to illustrate why I call them bad.
It offers “an arsenal of disease-fighting tools for prevention, treatment, and coping with side effects” (Yes, it offers tools; but do those tools work?) And it promises to “change your internal environment so cancer can’t survive.” (Wow! If it could really do that, every oncologist in the world would enthusiastically adopt these methods and the authors would be eligible for a Nobel prize.)
For my first blog entry, I wanted to write about something important, and I couldn’t think of anything more important than a recent book by R. Barker Bausell: Snake Oil Science: The Truth About Complementary and Alternative Medicine. If you want to understand how medical research works, if you want to know what can lead patients and scientists to false conclusions, if you have ever used complementary or alternative medicine or have wondered why others do, if you value evidence over belief, if you care about the truth, you will find a treasure trove of information in this book.
Some of the treatments encompassed under “complementary and alternative medicine” (CAM) have been around for a long time. Before we had science, “CAM” was medicine. Back then, all we had to rely on was testimonials and beliefs. And even today, for most people who believe CAM works, belief is enough. But at some level, the public has now recognized that science matters and people are looking for evidence to support those beliefs. Advocates claim that recent research validates CAM therapies. Does it really? Does the evidence show that any CAM therapy actually works better than placebos? R. Barker Bausell asks that question, does a compellingly thorough investigation, and comes up with a resounding “NO” for an answer.
Bausell is the ideal person to ask such a question. He is a research methodologist: he designs and analyzes research studies for a living. Not only that: he was intimately involved with acupuncture research for the National Center for Complementary and Alternative Medicine (NCCAM). So when he talks about what can go wrong in research and why much of the research on CAM is suspect, he is well worth listening to.
