The following is a collaborative effort by Peter Lipson, MD, a usual contributor to Science-Based Medicine, and Ames Grawert, JD, a soon-to-be-sworn-in attorney working in New York City.
Proponents of science-based medicine have always had one major problem—human beings are natural scientists, but we are also very prone to cognitive mis-steps. When we follow the scientific method we have developed, we succeed very well in understanding and manipulating our environment. When we follow our instincts instead, we frequently fail to understand cause and effect. This is how people on the fringes of medicine and science survive—intentionally or otherwise, they exploit our natural tendency to have too much faith in our own non-systematic observations.
One of the most important examples of this is the anti-vaccination movement (hereafter called the “infectious disease promotion movement” or IDPM). There have always been those suspicious of medicine and science, but the IDPM has taken this a step farther. They encourage people to “go with the gut”, ignoring centuries of science and public health data in favor of superstition. It’s not hard to exploit a parent’s fears. But exploiting these fears leads to real harm as many of us in the blogosphere have documented (and documented, and documented).
The IDPM is so fixed on their false beliefs that vaccination causes some sort of serious harm that they cannot be swayed by evidence. As each piece of their hypothesis is disproved, they move on to the next. Thimerosal doesn’t lead to autism? Then maybe it’s “the toxins”. Once the idea is fixed, there is no way to dislodge it. It simply shifts around a bit.
Since there is no science to lend legitimacy to the infectious disease promoters, they must rely on appeals to emotion. Most of their websites are full of testimonials, misinformation, and outright hostility. And when they really get backed into a corner, rather than hunkering down to do some real science, they sue.
