“Culture catechizes,” Alan Jacobs, a distinguished professor of humanities in the honors program at Baylor University, told me. Culture teaches us what matters and what views we should take about what matters. Our current political culture, Jacobs argued, has multiple technologies and platforms for catechizing—television, radio, Facebook, Twitter, and podcasts among them. People who want to be connected to their political tribe—the people they think are like them, the people they think are on their side—subject themselves to its catechesis all day long, every single day, hour after hour after hour.
