Before I became a journalist, I was an academic cultural theorist. If you want to construct a scholarly argument, you cite other people. In journalism, it’s basically the same. But whatever academics or journalists claim, no matter how many times we do it, no matter how committed we are to sticking to the facts, absolute certainty does not exist. When I was transitioning out of teaching at Yale en route to my current vocation, I took a brief detour through a journalism graduate program.
