In recent dramatic and often unequivocal headlines—such as with this BBC article—"DDT: Pesticide linked to Alzheimer's—news agencies across the globe have been promoting claims that the insecticide DDT may cause Alzheimer's. This is not the first time that DDT has been linked to causing some or another ailment, and probably won't be the last. But stastically distant "links"—what scientists call correlation—is just not sufficient evidence of a cause-effect relationship, and that presents a challenge to journalists who make scientific claims based on preliminary studies.
Ever since Rachel Carson's 1962 Silent Spring, DDT has been alleged to cause obesity, diabetes, autism, and so forth. In fact, DDT has been accused of causing almost every human malady imaginable, and practically every such claim has garnered newspaper headlines. In a classic case, in 1983, one small scale study led to widespread media reports that DDE, a breakdown product of DDT, was a cause of breast cancer. It was a false alarm. Eight years later a much larger study found, in fact, that DDE was not a cause of breast cancer-yet this far more credible study garnerd almost no media coverage, and so the false perception largely remains
