Ezra Klein has a provocative answer:

Increasingly, though, the incentives [for television appearances] are changing. Assume that the incentive for going on television is to raise your profile (which is about 75 percent correct). If I went on television five years ago, a large part of my incentive would be to make the host like me. After all, these appearances pass in an instant, and most of you would never see the program. So if I want to reach the maximum number of people with my arguments and do the most to increase my visibility, I want to keep coming back.

Now, however, with YouTube and GoogleVideo and online archiving, a single, contentious appearance can be seen on the internet a million times. Everyone, after all, has seen Stewart berate Tucker Carlson on Crossfire, but very few of us had actually tuned in that day. Similarly, my segment on the Kudlow show, replayed on the internet a few thousand times, did much more for my reputation among the audience relevant to my success than have my more friendly, but bland, appearances on other shows.

Making sense often requires you to be disruptive, and not long ago, being disruptive was probably a bad idea. Now it's a good one. And since the channels are wising up and putting their videos online with advertising before them, they also want widespread online dissemination of appearances, and so their incentives are increasingly aligned with mine. Does this mean more folks will be making sense? Not necessarily. But it means their might be more room for sense-making.

To put it in terms of inequalities, I would agree that (disruptive + making sense) > (disruptive + nonsense) for most TV viewers, but that (disruptive + nonsense) > (polite + making sense) for most TV viewers as well.

One could argue that this means that the best pundits will be both disruptive and make sense, crowding out everyone else. Color me skeptical, however, for two reasons. First, it's much easier to be disruptive than it is to make sense, and so for an aspiring pundit, the risk-averse attention-getting strategy is making as big a stink as possible. Making sense is optional.

Second, sometimes making sense is not disruptive -- it's boring. Most of the time, life is not simple, does not fit neatly into ideological categories, and requires "on the one hand, on the other hand" calculations. This kind of analysis can be really, really boring to people -- especially if they crave informational shortcuts in the form of brightly colored answers.

Of course,to defend this position, I hereby challenge Ezra Klein to a mano-a-mano, no-holds-barred bloggingheads smackdown to debate the issue -- a prospect that scares other pundits.
