I’m always wrong. Even when Nonna is frustrated or angry that she has forgotten, she always smiles and always tells me she loves me. And then I’m sad: I know she certainly won’t remember the day of my wedding or any special days after that, nor will she remember my incredible partner and the life we’ve built together.

When we say that someone isn’t acting rationally, what we mean is that we do not understand the world in which the person’s actions are rational. The problem is not so much that Putin is irrational; the problem is that there is a world in which it is rational for him to move ever closer to a nuclear strike, and most Western analysts cannot comprehend the logic of that world.

The analytics revolution, which began with the movement known as Moneyball, led to a series of offensive and defensive adjustments that were, let’s say, catastrophically successful. Seeking strikeouts, managers increased the number of pitchers per game and pushed up the average velocity and spin rate per pitcher. Hitters responded by increasing the launch angles of their swings, raising the odds of a home run, but making strikeouts more likely as well. These decisions were all legal, and more important, they were all correct from an analytical and strategic standpoint.
