Can People Use Party Cues to Assess Policymaker Positions? Ecological Rationality and Political Heuristics

Scholars disagree about the ability of people to use heuristics to make political judgments, with some arguing that heuristics are easy-to-use pieces of information and others arguing that applying heuristics may require some degree of political expertise. We argue that these debates have been somewhat intractable because most prior work has not considered the ecological rationality of political judgments—that is, the potential for cues to yield accurate judgments about a clearly defined reference class. In this paper, we present the results of two studies exploring whether people use party labels to make judgments about a random sample of U.S. Representatives’ voting behaviors. We find that respondents consistently performed worse in guessing U.S. Representatives’ votes than if they had correctly used a simple partisan heuristic. There is also some evidence that people performed worse with the presence of more nonparty cues. Attention to politics had a positive relationship with accuracy in both studies, although the relationship was modest. The results suggest that party cues may be more difficult to apply than some research has suggested.
