Political judgments, perceptions of facts, and partisan effects

We test two competing hypotheses about the impact of partisanship and information on people's political judgments and perceptions of facts using Canadians' reactions to a major scandal. Our findings with respect to subjective political judgments confirm the argument that partisan predispositions are crucial. But there is no evidence to support the argument that the polarizing effect of partisanship is most evident among the most informed. When it comes to perceptions of “objective” facts, the results are consistent with Zaller's reception axiom: the more informed people are, the more likely they are to correctly perceive objective facts. Partisanship does not appear to affect these perceptions.
