一位曾經堅信創造論、反對演化論的人葛蘭模頓(Glenn Morton) 描述了自己過去如何忽視演化論的證據。他用「惡魔」的譬喻寫道:"Morton’s demon was a demon who sat at the gate of my sensory input apparatus and if and when he saw supportive evidence coming in, he opened the gate. But if he saw contradictory data coming in, he closed the gate. In this way, the demon allowed me to believe that I was right and to avoid any nasty contradictory data."
