We have become increasingly aware that supernatural thinking is something to be embarrassed about. We may even hide our superstitious behavior when there are others around. Three out of four adults will avoid walking under a ladder if they think they are unobserved.53 If they see another adult do it first, they are much more likely to walk under the ladder. If we do not think that we are being watched, we are more likely to act superstitiously. Students were even less likely to cheat when they were told casually that the exam room was said to be haunted.54
