Public opinion scholars have recently focused on understanding why surveys report such high levels of misinformation among otherwise knowledgeable and engaged partisans. In this paper, we take advantage of a natural experiment involving the October 2012 jobs report announcement to gain a more complete understanding of how individuals’ beliefs are influenced by new salient information in a politicized environment.

Using a variety of techniques, including response latency measures, we conclude that partisans did react to the jobs report by engaging in motivated reasoning, providing a clearer understanding of why individuals respond to factual questions in vastly different ways.
