Chances are you heard some blatantly untrue statements during last night’s debate. It’s a cynical, manipulative strategy, but it works: Psychological studies have consistently shown that oft-repeated statements are more likely to be perceived as true, regardless of their actual veracity.
Since this “Illusory Truth Effect” was first noted in the late 1970s, it has been widely assumed that this ploy is effective only on people unfamiliar with the issue in question. Knowledge of the subject matter will lead people to dismiss the lie and distrust the liar, one might assume.
But a newly published study reports that’s not necessarily true: Even those of us with a solid grasp of the issue at hand are susceptible to this sort of misinformation. CONT.
