[close] Scientific error, says Robert Park, "has a way of evolving ... from self-delusion to fraud. I use the term voodoo science to cover them all: pathological science, junk science, pseudoscience, and fraudulent science." In pathological science, scientists fool themselves. Junk science refers to scientists who use their expertise to befuddle and mislead others (usually juries or lawmakers). Pseudoscience has the trappings of science without any evidence. Fraudulent science is, well, fraud--old-fashioned lying.

Park is well-acquainted with voodoo science in all its forms. Since 1982, he has headed the Washington, D.C., office of the American Physical Society, and he has carried the flag for scientific rationality through cold fusion, homeopathy, "Star Wars," quantum healing, and sundry attempts to repeal the laws of thermodynamics. Park shows why a "disproportionate share of the science seen by the public is flawed" (because shaky science is more likely to skip past peer review and head straight for the media), and he gives a good tour of recent highlights in Voodoo. He has a rare ability to poke holes compassionately, without excoriating those taken in by their fondest wishes. Park is less forgiving of scientists (especially Edward Teller) when he thinks they've fallen down on the job, a job that should include helping the public separate the scientific wheat from the voodoo chaff. --Mary Ellen Curtin [close]
