SCIENCE AND SKEPTICISM

Science is founded on the conviction that experience, effort, and reason are valid; magic on the belief that hope cannot fail nor desire deceive.

—Branislaw Malinowski, Magic, Science, and Religion, 1948

A Skeptic’s Manifesto

On the opening page of his splendid little book To Know a Fly, biologist Vincent Dethier makes this humorous observation about how children grow up to be scientists: “Although small children have taboos against stepping on ants because such actions are said to bring on rain, there has never seemed to be a taboo against pulling off the legs or wings of flies. Most children eventually outgrow this behavior. Those who do not either come to a bad end or become biologists” (1962, p. 2). In their early years, children are knowledge junkies, questioning everything in their purview, though exhibiting little skepticism. Most never learn to distinguish between skepticism and credulity. It took me a long time.

In 1979, unable to land a full-time teaching job, I found work as a writer for a cycling magazine. The first day on the job, I was sent to a press conference held in honor of a man named John Marino who had just ridden his bicycle across America in a record 13 days, 1 hour, 20 minutes. When I asked him how he did it, John told me about special vegetarian diets, megavitamin therapy, fasting, colonies, mud baths, iridology, cytotoxic blood testing, Rolfing, acupressure and acupuncture, chiropractic and massage therapy, negative ions, pyramid power, and a host of weird things with which I was unfamiliar. Being a fairly inquisitive fellow, when I took up cycling as a serious sport I thought I would try these things to see for myself whether they worked. I once fasted for a week on nothing but a strange mixture of water, cayenne pepper, garlic, and lemon. At the end of the week, John and I rode from Irvine to Big Bear Lake and back, some seventy miles each way. About halfway up the mountain I collapsed, violently ill from the concoction. John and I once rode out to a health spa near Lake Elsinore for a mud bath that was supposed to suck the toxins out of my body. My skin was dyed red for a week. I set up a negative ion generator in my bedroom to charge the air to give me more energy. It turned the walls black with dust. I got my iris read by an iridologist, who told me that the little green flecks in my eyes meant something was wrong with my kidneys. To this day my kidneys are functioning fine.

I really got into cycling. I bought a racing bike the day after I met John and entered my first race that weekend. I did my first century ride (100 miles) a month later, and my first double century later that year. I kept trying weird things because I figured I had nothing to lose and, who knows, maybe they would increase performance. I tried colonics because supposedly bad things clog the plumbing and thus decrease digestive efficiency, but all I got was an hour with a hose in a very uncomfortable place. I installed a pyramid in my apartment because it was supposed to focus energy. All I got were strange looks from guests. I starting getting massages, which were thoroughly enjoyable and quite relaxing. Then my massage therapist decided that “deep tissue” massage was best to get lactic acid out of the muscles. That wasn’t so relaxing. One guy massaged me with his feet. That was even less relaxing. I tried Rolfing, which is really deep tissue massage. That was so painful that I never went back.

In 1982 John and I and two other men competed in the first Race Across America, the 3,000-mile, nonstop, transcontinental bike race from Los Angeles to New York. In preparation, we went for cytotoxic blood testing because it was supposed to detect food allergies that cause blood platelets to clump together and block capillaries, thus decreasing blood flow. By now we were a little skeptical of the truth of these various claims, so we sent in one man’s blood under several names. Each sample came back with different food allergies, which told us that there was a problem with their testing, not with our blood. During the race, I slept with an “Electro-Acuscope,” which was to measure my brain waves and put me into an alpha state for better sleeping. It was also supposed to rejuvenate my muscles and heal any injuries. The company swore that it helped Joe Montana win the Super Bowl. Near as I can figure, it was totally ineffective.

The Electro-Acuscope was the idea of my chiropractor. I began visiting a chiropractor not because I needed one but because I had read that energy flows through the spinal cord and can get blocked at various places. I discovered that the more I got adjusted, the more I needed to get adjusted because my neck and back kept going “out.” This went on for a couple of years until I finally quit going altogether, and I’ve never needed a chiropractor since.

All told, I raced as a professional ultra-marathon cyclist for ten years, all the while trying anything and everything (except drugs and steroids) that might improve my performance. As the Race Across America got bigger—it was featured for many years on ABC’s Wide World of Sports—I had many offers to try all sorts of things, which I usually did. From this ten-year experiment with a subject pool of one, I drew two conclusions: nothing increased performance, alleviated pain, or enhanced well-being other than long hours in the saddle, dedication to a consistent training schedule, and a balanced diet; and it pays to be skeptical. But what does it mean to be skeptical?
