Recent political movements within the United States have raised concerns about the health of American democracy. With hyper-partisanship dividing the country and Donald Trump—the most unlikely, unsuitable, and unpopular presidential nominee of a major party in American history—securing the Republican nomination, the question emerges of whether democracy in America has gone awry. And if so, is it too much or too little democracy that’s to blame?
To help address those questions, in this paper, Thomas E. Mann summarizes and discusses the findings of Christopher Achen and Larry Bartels’ ambitious treatise on American democracy: “Democracy for Realists.” Achen and Bartels contend that the traditional conception of voters as rational, attentive decision-makers does not hold against empirical evidence. Instead, voters are best understood as members of partisan groups, which influence their perception of candidates, issues, and even simple facts. According to Achen and Bartels, perceived social identities drive voting decisions, rather than rationality.
Mann notes that most scholars would agree that voters do not follow the expectations of idealistic models, but draws attention to competing theories that are far less damning to voters’ rationality. In particular, the research of Paul Sniderman and Arthur Lupia suggests that voters are far more capable than Achen and Bartels would assert. In their view, voters have enough rationality and information to ensure a well-functioning democracy.
