Rumor’s Reasons

By FARHAD MANJOO

In the summer of 2004, Andy Martin, a colorful Web columnist and sometime Republican candidate for state office, put out a press release announcing his sadness at having to “expose” Barack Obama as a “Muslim who has concealed his religion.” Reporters ignored Martin’s charge, which offered no proof. But the story took root: Martin’s screed bounced about blogs, mutating over the course of a couple years into an e-mail message that suggested the senator is a kind of Muslim Manchurian candidate for the White House.

Though news organizations and fact-checking Web sites like Snopes.com have debunked the claim, the story just won’t die. In an NBC/Wall Street Journal poll taken in December, 8 percent of respondents thought Obama was Muslim, half as many as correctly identified him as a Protestant.

The Obama-is-a-Muslim rumor does not seem to have hurt the candidate’s fortunes, at least not yet. But the myth’s persistence illustrates a growing cultural vulnerability to rumor. Journalists typically presume that facts matter: show the public what is true, and they will make decisions correctly. Psychologists who study how we separate truth from fiction, however, have demonstrated that the process is not so simple. And because digital technology fosters social networks that are both closely knit and far-flung, rumors are now free to travel widely within certain groups before they meet any opposition from the truth.

Consider, for starters, this paradox of social psychology, a problem for myth busters everywhere: repeating a claim, even if only to refute it, increases its apparent truthfulness. In 2003, the psychologist Ian Skurnik and several of his colleagues asked senior citizens to sit through a computer presentation of a series of health warnings that were randomly identified as either true or false — for example, “Aspirin destroys tooth enamel” (true) or “Corn chips contain twice as much fat as potato chips” (false). A few days later, they quizzed the seniors on what they had learned.
