FOLK TRUTHS: HOW THE MEDIA USE THEM TO LIE by H. Peter Metzger, Ph.D. (9/8/88) By "Folk Truths" I mean claims that are held to be facts by the media, but which can be seen, after serious reflection by almost anyone, to be obvious lies. They are nothing more than propaganda, stories made up to support a political conclusion, but with one major difference: They are all dolled up in scientific mumbo-jumbo, which makes them acceptable to people who wanted to believe them in the first place but who needed a better reason than merely their own political passion. Examples of folk truths range from the basis for the reasons why Americans of Japanese descent were forced into relocation camps in America during World War II, to how giant public works projects, like dams and pipelines, were cancelled over fears that they would disturb a rare fish or a plant, which turned out later wasn't so rare after all. In looking back on some of these fiascos, it's easy ridicule the folk truths of another time. But it's always been more amusing to me to investigate the folk truths of today, at a time when most people still believe in them. And what I find most interesting is not so much the debunking of them (which Petr does so well in AtE) but the mechanism by which these folk truths got started in the first place. And so I thought you FREEMEN might be interested in some I've tracked over the years. I'll start with this currently fashionable claim: "America is such a cruel country that its old people have to eat cat food in order to survive". Naturally, since we're talking about lies here, the people that start these folk truths have very personal reasons for doing so. Sometimes it's just for the ego-pumping notoriety of it all, but usually it's a political activist that makes an attention-getting claim for some special political advantage. That's how this one got started: In 1985 a woman from a small Vermont town testified before the governor's task force on hunger that her neighbor had resorted to eating pet food because she couldn't afford to buy regular meat on her fixed-income. Many similar claims have been made before and since, but this one led directly to justification by scientific mumbo-jumbo. The media find it difficult to make a big issue by quoting the claims of a single person. So the original claim must be strengthened by having a group of authorities jump on the bandwagon. One authority is seldom enough but when a single authority can be made to seem to be a much larger group (as in "The New York Times says ...", when it's really only one reporter doing the writing), then a single authority will do. That's what happened in this case: In 1986, a second-year medical student wrote to The New England Journal of Medicine concerning the above claim. In a letter-to-the- editor (not in a scientific article,) she compared the nutritional values of cat food (as supplied by the companies) with published recommended daily allowances and found that they presented a "benign nutritional profile", not a surprising conclusion since cats live off the stuff.
