In the world of magazines, of course, none of us is immune to slickness or oversimplification—New York included. But two things make Lehrer’s glibness especially problematic, and especially representative. First, conferences and corporate speaking gigs have helped replace the journalist-as-translator with the journalist-as-sage; in a magazine profile, the scientist stands out, but in a TED talk, the speaker does. And second, the scientific fields that are the most exciting to today’s writers—neuroscience, evolutionary biology, behavioral economics—are fashionable despite, or perhaps because of, their newness, which makes breakthrough findings both thrilling and unreliable. In these fields, in which shiny new insights so rarely pan out, every popularizer must be, almost by definition, a huckster. When science doesn’t give us the answers we want, we find someone who will.
