If you were wrong about something important, how quickly would you want to know and how quickly would you want to do something about it? Unfortunately, the answer isn’t nearly as obvious as we’d like to think.
Mark Twain sagely noted that a lie can travel half way around the world while the truth is putting on its shoes. That’s because the truth is so much messier. Lies are created to be believable. They cater to our prejudices, whims, desires and hopes even when the truth cannot. Lies offer a good story when the truth does not. They are plausible when the truth is not. We often resist and even deny the truth. It is inherently unwieldy. It requires a careful sifting and analysis of facts in order to be discerned — we want deduction but are limited to induction most of the time. The truth is simply very hard to handle.
Of course, if we’re talking about relatively trivial matters (perhaps the distance from the earth to the moon) or about something we’re predisposed to believe anyway, we adjust our beliefs quite readily. But when truth doesn’t fit with what is important to us — when it matters — our perception of it gets caught up in who we perceive ourselves to be and in our vested interests. In those instances, attacking false information with data and related evidence often backfires, having the opposite of the desired effect. We like to think that straightforward education overcomes falsehoods, but things aren’t nearly that simple. This horrifying phenomenon — the backfire effect — was demonstrated once again recently in a study of the responses of parents to various forms of reporting that vaccines are not dangerous.
