Polarization of political reading

posted by Jason Kottke Nov 04, 2008

Valdis Krebs uses data from Amazon to chart networks of people who read political books. Two groups typically emerge from the data: people who read liberally oriented books and people who read conservatively oriented books with a couple of books that both groups read. He ran his analysis again a few days ago and found not two groups but three — roughly: 1) pro-Obama, 2) anti-Bush, and 3) conservative — and no books that the groups read in common. (via big sort)
