Why do people despise those who are politically different from themselves? The answer lies with a widespread cognitive phenomenon called group polarization. When you talk only to those you agree with, or listen only to news that affirms your opinions, you become more radical in your beliefs.

As people radicalize like this, they grow less able to comprehend opposing views, more likely to dismiss objections to their opinions and increasingly prone to regarding dissenters as incompetent and depraved.

Recall the last time you were present in a packed arena watching your favorite team win a home game. As you roared along with your fellow fans, everyone’s enthusiasm for the team spiked. At the same time, animosity for the opposing team and its fans intensified. Your mood was elevated and your identity was affirmed. Cheering with fellow fans makes us feel good about ourselves.

Online environments function as immense polarization machines. They enable individuals to select their information sources and filter out challenging or unfamiliar messages.
