One very clear example can be seen among those who believe that the library holds materials that violate obscenity law. They say this is criminal, and yet refrain from filing a formal complaint with the police, a strong example of living with cognitive dissonance. Of course, they won’t file a formal complaint because they fear the real-world consequences of filing a false police report, and that means that at some level they realize that the obscenity claim is false. But the energy created by touching the child-protection instinct is so strong that it keeps that realization from coming too close to conscious awareness. The goad to action overrides the awareness that something here just doesn’t add up.
