“The medical science priesthood has a long history of treating outside-the-box thinkers harshly. Toward the end of the 18th century, Britain’s Royal Society refused to publish Edward Jenner’s discovery that inoculating people with material from cowpox pustules—a technique he called “vaccination,” from the Latin word for cow, vacca—prevented them from getting the corresponding human disease, smallpox. Jenner’s medical colleagues considered this idea dangerous; one member of the Royal College of Physicians even suggested that the technique could make people resemble cows.
At the time, many physicians were making a good living by performing variolation, which aimed to prevent smallpox by infecting patients with pus from people with mild cases. Some saw vaccination as a threat to their income. Thankfully, members of Parliament liked Jenner’s idea and appropriated money for him to open a vaccination clinic in London. By the early 1800s, American doctors had adopted the technique. In 1805, Napoleon ordered smallpox vaccination for all of his troops.
Half a century later, the prestigious Vienna General Hospital fired Ignaz Semmelweis from its faculty because he required his medical students and junior physicians to wash their hands before examining obstetrical patients. Semmelweis connected puerperal sepsis—a.k.a. “childbed fever,” then a common cause of postnatal death—to unclean hands. Ten years after Semmelweis returned to his native Budapest, he published The Etiology, Concept and Prophylaxis of Childbed Fever. The medical establishment rained so much vitriol on him that it drove him insane. (Or so the story goes: Some think, in retrospect, that Semmelweis suffered from bipolar disorder.) He died in an asylum in 1865 at the age of 47.
The “germ theory” anticipated by Semmelweis did not take hold until the late 1880s. That helps explain why, in 1854, the public health establishment rebuffed the physician John Snow after he traced a London cholera epidemic to a water pump on Broad Street. Snow correctly suspected that water from the pump carried a pathogen that caused cholera.
Public health officials clung instead to the theory that the disease was carried by a miasma, or “bad air.” The British medical journal The Lancet published a brutal critique of Snow’s theory, and the General Board of Health determined that his idea was “scientifically unsound.” But after another outbreak of cholera in 1866, the public health establishment acknowledged the truth of Snow’s explanation. The incident validated the 19th century classical liberal philosopher Herbert Spencer’s warning that the public health establishment had come to represent entrenched political interests, distorting science and prolonging the cholera problem. “There is an evident inclination on the part of the medical profession to get itself organized after the fashion of the clericy,” he wrote in 1851’s Social Statics. “Surgeons and physicians are vigorously striving to erect a medical establishment akin to our religious one. Little do the public at large know how actively professional publications are agitating for state-appointed overseers of the public health.””

“It may be true that, as American science fiction and fantasy writer Theodore Sturgeon said, “90 percent of everything is crap.” But the remaining 10 percent can be important. Health care professionals who see only the costs of their patients’ self-guided journeys through the medical literature tend to view this phenomenon as a threat to the scientific order, fueling a backlash. Their reaction risks throwing the baby out with the bathwater.”

“Openness to unconventional ideas has its limits. We don’t take flat-earthers seriously. Nor should we lend credence to outlandish claims that COVID-19 vaccines cause infertility, implant people with microchips, or change their DNA. There are not enough hours in the day to fully address every question or hypothesis. But a little tolerance and respect for outsiders can go a long way. If those habits become the new norm, people will be more likely to see rejection of challenges to the conventional wisdom as the objective assessment of specialists rather than the defensive reaction of self-interested elites. Science should be a profession, not a priesthood.”
