Truthiness a Casualty in Reality

According to a serious study undertaken by researchers at Ohio State both liberals and conservatives find Stephen Colbert funny. No harm in that. On the other hand conservatives don't know he's joking:

Additionally, there was no significant difference between the groups in thinking Colbert was funny, but conservatives were more likely to report that Colbert only pretends to be joking and genuinely meant what he said while liberals were more likely to report that Colbert used satire and was not serious when offering political statements. Conservatism also significantly predicted perceptions that Colbert disliked liberalism.

See, that's what makes these people so dangerous.
