"Why does more education lead to less accurate beliefs? The answer returns us to the difference between rational voters (what we think we are) and rationalizing voters (what we really are). It turns out that the human mind is a marvelous information filter, adept at blocking out those facts that contradict what we’d like to believe.
Just look at this experiment, which was done in the late 1960’s, by the cognitive psychologists Timothy Brock and Joe Balloun. They played a group of people a tape-recorded message attacking Christianity. Half of the subjects were regular churchgoers while the other half were committed atheists. To make the experiment more interesting, Brock and Balloun added an annoying amount of static – a crackle of white noise – to the recording. However, they allowed listeners to reduce the static by pressing a button, so that the message suddenly became easier to understand. Their results were utterly predicable and rather depressing: the non-believers always tried to remove the static, while the religious subjects actually preferred the message that was harder to hear. Later experiments by Brock and Balloun demonstrated a similar effect with smokers listening to a speech on the link between smoking and cancer. We silence the cognitive dissonance through self-imposed ignorance."
