The challenge posed by this political crisis is how to take the stupidity seriously without reducing it to a wholly mental or psychiatric, let alone genetic, phenomenon. Stupidity can be understood as a problem of social systems rather than individuals, as André Spicer and Mats Alvesson explore in their book The Stupidity Paradox. Stupidity, they write, can become “functional,” a feature of how organizations operate on a daily basis, obstructing ideas and intelligence despite the palpable negative consequences. Yet it’s hard to identify anything functional about Trumpian stupidity, which is less a form of organizational inertia or disarray than a slash-and-burn assault on the very things — universities, public health, market data — that help make the world intelligible.
