The Folly of Fools ~NYTIMES book review
Our big brains and communication skills make us master dissemblers. Even before we can speak, Trivers notes, we learn to cry insincerely to manipulate our caregivers. As adults, we engage in "confirmation bias," which makes us seize on facts that bolster our preconceptions and overlook contradictory data. We wittingly and unwittingly inflate the qualities of ourselves and others in our religious, political or ethnic group. We denigrate those outside our in-group as well as sexual and economic rivals. Fooling others yields obvious benefits, but why do we so often fool ourselves? Trivers provides a couple of answers. First, believing that we're smarter, sexier and more righteous than we really are -- or than others consider us to be -- can help us seduce and persuade others and even improve our health, via the placebo effect, for example. And the more we believe our own lies, the more sincerely, and hence effectively, we can lie to others. "We hide reality from our conscious minds the better to hide it from onlookers," Trivers explains. But our illusions can have devastating consequences, from the dissolution of a marriage to stock-market collapses and world wars.
