Why the Old A2K was great

The result is polarization and intolerance. Cass Sunstein, a Harvard law professor now working for President Obama, has conducted research showing that when liberals or conservatives discuss issues such as affirmative action or climate change with like-minded people, their views quickly become more homogeneous and more extreme than before the discussion. For example, some liberals in one study initially worried that action on climate change might hurt the poor, while some conservatives were sympathetic to affirmative action. But after discussing the issue with like-minded people for only 15 minutes, liberals became more liberal and conservatives more conservative.

The decline of traditional news media will accelerate the rise of The Daily Me, and we’ll be irritated less by what we read and find our wisdom confirmed more often. The danger is that this self-selected “news” acts as a narcotic, lulling us into a self-confident stupor through which we will perceive in blacks and whites a world that typically unfolds in grays.

So what’s the solution? Tax breaks for liberals who watch Bill O’Reilly or conservatives who watch Keith Olbermann? No, until President Obama brings us universal health care, we can’t risk the surge in heart attacks.

So perhaps the only way forward is for each of us to struggle on our own to work out intellectually with sparring partners whose views we deplore. Think of it as a daily mental workout analogous to a trip to the gym; if you don’t work up a sweat, it doesn’t count.
