Punditry is an industry built on confirmation bias. Rush Limbaugh and Keith Olbermann, Glenn Beck and Arianna Huffington, Rachel Maddow and Ann Coulter - These people provide fuel for beliefs, they pre-filter the world to match existing worldviews. If their filter is like your filter, you love them. If it isn't, you hate them. You watch them not for information, but for confirmation.
