Anecdotal Evidence (testimonials)

via Unnatural Acts that can improve your thinking

anecdote_250pxTestimonials and anecdotes are used to support claims in many fields. Advertisers often rely on testimonials to persuade consumers of the effectiveness or value of their products or services. Others use anecdotes to drive home the horror of some alleged activity or the danger of widely-used electronic devices like cell phones. In the mid-90s, there were many people, some in law enforcement, claiming that Satanists were abducting and abusing children on a massive scale. The anecdotes involved vivid descriptions of horrible sexual abuse, even murder of innocent children. The anecdotes were quite convincing, especially when they were repeated on nationally televised programs with popular hosts like Geraldo Rivera. A four-year study in the early 1990s found the allegations of satanic ritual abuse to be without merit. Researchers investigated more than 12,000 accusations and surveyed more than 11,000 psychiatric, social service, and law enforcement personnel. The researchers could find no unequivocal evidence for a single case of satanic cult ritual abuse.

There have also been scares fueled by anecdotes regarding such disparate items as silicone breast implants, cell phones, and vaccinations. In the 1990s many women blamed their cancers and other diseases on breast implants. Talk show hosts like Oprah Winfrey and Jenny Jones presented groups of women who were suffering from cancer or some other serious disease and who had been diagnosed after they’d had breast implants. The stories tugged at the heartstrings and brought tears to many sensitive eyes, but the scientific evidence did not exist that there was a causal connection between the implants and any disease. That fact did not prevent lawyers from extorting $4.25 billion from implant manufacturers. Marcia Angell, former executive editor of the New England Journal of Medicine, brought the wrath of feminist hell upon herself in 1992 when she wrote an editorial challenging the Food and Drug Administration’s decision to ban the manufacture of silicone breast implants. The scientific evidence wasn’t there to justify the ban. She eventually wrote a book describing the fiasco: Science on Trial: The Clash of Medical Evidence and the Law in the Breast Implant Case. The scientific evidence is now in. The implants don’t cause cancer or other diseases, and the FDA has lifted its ban. When the data were collected, they showed that women with silicone breast implants did not suffer cancer or any other disease at a significantly higher rate than women who had not had implants.

The public fear that cellphones might be causing brain tumors was first aroused not by scientists but by a talk show host. On January 23, 1993, Larry King’s guest was David Reynard, who announced that he and his wife Susan had sued NEC and GTE on the grounds that the cellphone David gave Susan caused his wife’s brain tumor. There was nothing but junk science to back up her claim, plus the fact that . . .
