In 1960, about one American in twenty said they would mind if their child married someone from the other party. Fifty years later, about half of Republicans and a third of Democrats said so, even though most voters' actual opinions had not moved nearly as far apart. Something besides disagreement was growing, and figuring out what it is turns out to be one of the more interesting puzzles in modern politics.

Here you will learn to tell real policy differences from tribal hostility and from the distorted picture each side carries of the other. You will weigh the evidence on cable news, social media, primaries, party competition and identity, compare the United States with other democracies, and look at what experiments say actually lowers the temperature. Afterward, a headline claiming the country has never been more divided will read as a question rather than a verdict.
