In-your-face talking heads shout over one another on your TV screen. Extreme close-ups feature prominent politicians in proportions that violate real-life social norms.
By now these are familiar constructs of cable news talk shows like the top-rated "The O'Reilly Factor." But the real O'Reilly factor (as with Maddow, Matthews, Sharpton, Schultz, O'Donnell, Hannity, Van Susteren, Cooper or Morgan) may be how political television can contribute to political polarization and partisan paralysis.
That's the data-driven conclusion of Prof. Diana Mutz, director of the Institute for the Study of Citizens and Politics at the University of Pennsylvania's Annenberg School for Communication.
Mutz, who recently presented her research at the University of Minnesota, said that these programs, as well as some on broadcast TV, are "in your face in a very literal sense, in a way that doesn't occur in our perceptual processes in everyday life."
To demonstrate, Mutz showed footage of the 2004 media meltdown between MSNBC's Chris Matthews and former Georgia Democratic Sen. Zell Miller (who wistfully recalled days of duels). Their angry exchange featured faces far closer than in most real-life discourse.
"What we know about facial close-ups is they intensify emotional reactions," Mutz said, not just of the angry combatants, but of those watching. "Particularly in the context of disagreement, this is problematic. Because when we disagree with someone in the face-to-face world, our natural reaction -- regardless of culture and what your normal level of social distance is -- we back up. We put greater distance between someone we have disagreement with. And yet many times in the TV world we see the exact opposite."
Mutz's observations are based on research that includes content analysis of 10 shows every 10 years dating back to 1969. The most significant swing is from 1979 to 1989, the era of great growth in cable penetration.
Since then, Mutz calculates, the number of conflicts per broadcast hasn't changed, but story pacing has quickened, and the "percentage of conflicts featuring identifiable faces" has soared from 60 percent to nearly 100 percent today. This personalization of politics is met with a doubling of the percentage of the TV screen taken up by the human body, from 20 percent to about 40 percent today.
