We

We live in an age of political polarization. As political beliefs on the left and the right have been pulled closer to the extremes, so have our social environments: we seldom interact with those with whom we don't see eye to eye. Making matters worse, we are being appealed to—by companies, products, and teams, for example—based on our deep-seated, polarized beliefs. Our choice of Starbucks or Dunkin' Donuts, Costco or Sam's Club, soccer or football, New York Times vs. Wall Street Journal is an expression of our beliefs and a reinforcement of our choice to stay within the confines of our self-selected political community, making us even more polarized.
