Of all the status obsessions that preoccupy our elites, none is quite so prominent as the obsession with smartness. Intelligence is the core value of the meritocracy, one that stretches back to the early years of standardized testing, when the modern-day SAT descended from early IQ tests. To call a member of the elite “brilliant” is to pay that person the highest compliment. Intelligence is a vitally necessary characteristic for those with powerful positions. But it isn’t just a celebration of smartness that characterizes the culture of meritocracy. It’s something more pernicious: a Cult of Smartness in which intelligence is the chief virtue, along with a conviction that smartness is rankable and that the hierarchy of intelligence, like the hierarchy of wealth, never plateaus. In a society as stratified as our own, this is a seductive conclusion to reach. Since there are people who make $500,000, $5 million and $5 billion all within the same elite, perhaps there are leaps equal to such orders of magnitude in cognitive ability as well.
