"For if we choose only to expose ourselves to opinions and viewpoints that are in line with our own, studies suggest that we will become more polarized and set in our ways. And that will only reinforce and even deepen the political divides in this country. But if we choose to actively seek out information that challenges our assumptions and our beliefs, perhaps we can begin to understand where the people who disagree with us are coming from.

This of course requires that we all agree on a certain set of facts to debate from, and that is why we need a vibrant and thriving news business that is separate from opinion makers and talking heads. As Senator Daniel Patrick Moynihan famously said, "Everyone is entitled to his own opinion, but not his own facts."

Still, if you're someone who only reads the editorial page of The New York Times, try glancing at the page of The Wall Street Journal once in awhile. If you're a fan of Glenn Beck or Rush Limbaugh, try reading a few columns on the Huffington Post website. It may make your blood boil; your mind may not often be changed. But the practice of listening to opposing views is essential for effective citizenship."
