Evan has a habit. He's not ashamed of it, but he doesn't want to reveal too much about himself, lest his colleagues learn how he's spending so much of his time.

But his fixation takes a particular form: with every browser refresh, he hopes math will reveal the future. Evan is a poll obsessive, FiveThirtyEight strain-a subspecies I recognize because I'm one of them, too.
