We human beings are credulous creatures at any age. We love to believe in marvels and miracles, and sometimes I think we will believe anything. In fact, the less likely it is, the more we want to believe it. I’m thinking of politics, of course, and the stock market, and the social media and certain TV news programs. The psychological mechanism that allows us to swallow the most implausible rubbish is both simple and ancient. Julius Caesar expressed it succinctly, although in Latin, 2,000 years ago: “Men will gladly believe what they want to believe.” And I’m sure that women have the same talent.
