The dangers of pseudoscience--parapsychology, astrology,creationism, etc.--are widely criticized. Lessons in the history of science are often viewed as an educational remedy by conveying the nature of science. But such histories can be flawed. In particular, many stories romanticize scientists, inflate the drama of their discoveries,and oversimplify the process of science. They are, literally and rhetorically, myths.While based on real historical events, they distort the basis of scientific authority and foster unwarranted stereotypes. Such stories are "pseudohistory". Like pseudoscience, they promote false ideas about science--in this case, about how science works. Paradoxically, perhaps,the history of pseudosciences may offer an excellent vehicle for remedying such impressions.
