In this study, I use qualitative and quantitative methods to gauge the effect that consumption of highly polarized news-media (i.e. Glen Beck, Chris Matthews, etc.) has on its consumers. Using PEW survey data, I compare those who frequently consume such media against those who do not, and I find that consumers of polarized media are more likely to score highly on a current events test, and are more likely to be registered to vote, with 95% confidence.
