What can we learn from the cycles of history about political disintegration and recovery? Peter Turchin predicted the tumult.

As the U.S. diversifies, political representation is not keeping pace. But that doesn’t mean we can blame the voters.

These moderates matter for election o...

Elon Musk’s takeover of Twitter is producing a firestorm of controversy, especially among journalists, political professionals, and academics. But how did Twitter become the preferred platform for journalists to interact with politicos and professors, the key conduit for research and opinion to make their way to media coverage, and the center of elite discourse? This week, I talk to Shannon McGreg...

Democrats and Republicans are electing new leaders for their parties in the U.S. House and Senate, as a new era begins with the replacement of Speaker Nancy Pelosi.

People who are pro-choice on abortion also tend to be against the death penalty. But are those beliefs internally connected? Would changing one belief change the other? And do all of our views add up to a coherent belief system?

Public opinion polls often show large majorities in favor of hypothetical changes in public policy, such as universal background checks for gun purchases. But when voters have the opportunity to enact those changes in ballot measure initiative campaigns, the results are usually much closer.
