On the morning after the 2016 presidential election I tried to distract myself by reading some pages of Thucydides that I had assigned for a class the next day, and found myself reading the clearest explanation I had seen of the vote that I was trying to forget. In the third book of his History of the Peloponnesian War, Thucydides describes the outbreak of civil war on the northern island of Corcyra in 427 BC:
There was the revenge taken in their hour of triumph by those who had in the past been arrogantly oppressed instead of wisely governed; there were the wicked resolutions taken by those who, particularly under the pressure of misfortune, wished to escape from their usual poverty and coveted the property of their neighbors; there were the savage and pitiless actions into which men were carried not so much for the sake of gain as because they were swept away into an internecine struggle by their ungovernable passions.
The closest thing to a consolation that I found in the election was the catastrophic failure of almost every attempt to predict the outcome by using numerical data, instead of interpreting the passions that provoked it, as Thucydides interpreted the conflict in Corcyra. The most confident pre-election pollsters proclaimed themselves 99 percent certain of the result that didn’t happen. Even the least confident predicted exactly what did not occur.
