Acne illustrates the problem. The dermatological party line is that diet doesn’t cause acne. According to a website of the American Academy of Dermatology, “extensive scientific studies” show it’s a “myth” that “acne is caused by diet.” According to “guidelines for care” for dermatologists published in 2007, “dietary restriction (either specific foods or food classes) has not been demonstrated to be of benefit in the treatment of acne.” In fact, there is overwhelming evidence linking diet and acne. Starting in the 1970s, a Connecticut doctor named William Danby collected evidence connecting dairy consumption and acne; it is telling that Danby wasn’t a professional scientist. When his patients gave up dairy, it often helped. In 2002, six scientists (none a dermatologist) published a paper with the Weston Price–like conclusion that two isolated groups of people (Kitava Islanders and Ache hunter-gatherers) had no acne at all. They had examined more than 1,000 subjects over the age of 10 and found no acne. When people in these groups left their communities and ate differently, they did get acne. These observations suggest that a lot of acne—maybe all of it—can be cured and prevented by diet.
Why is the official line so wrong? Because the painstaking research needed to show the many ways diet causes acne is the sort of research that professional researchers can’t do and don’t want to do. They can’t do it because the research would be hard to fund (no one makes money when patients avoid dairy) and because the trial and error required would take too long per publication. They don’t want to do it because it would be low-tech, low-cost, and very useful—and therefore low-status. While research doctors in other specialties study high-tech expensive treatments, they would be doing low-cost studies of what happens when you avoid certain foods. Humiliating. Colleagues in other specialties might make fun of them. To justify their avoidance of embarrassment, the whole profession tells the rest of us, based on “extensive scientific studies,” that black is white. Self-experimentation allows acne sufferers to ignore the strange claims of dermatologists, not to mention their dangerous drugs (such as Accutane). Persons with acne can simply change their diets until they figure out what foods cause the problem.
Gregor Mendel was a monk. He was under no pressure to publish; he could say whatever he wanted about horticulture without fear for his job. Charles Darwin was wealthy. He had no job to lose. He could write On the Origin of Species very slowly. Alfred Wegener, who proposed continental drift, was a meteorologist. Geology was a hobby of his. Because they had total freedom and plenty of time, and professional biologists and geologists did not (just as now), Mendel, Darwin, and Wegener were able to use the accumulated knowledge of their time better than the professionals.
