Essay by Ilya Somin in Special issue on Is Smaller Government Smarter Government? of Cato Unbound: ” Democracy is supposed to be rule of the people, by the people, and for the people. But in order to rule effectively, the people need political knowledge. If they know little or nothing about government, it becomes difficult to hold political leaders accountable for their performance. Unfortunately, public knowledge about politics is disturbingly low. In addition, the public also often does a poor job of evaluating the political information they do know. This state of affairs has persisted despite rising education levels, increased availability of information thanks to modern technology, and even rising IQ scores. It is mostly the result of rational behavior, not stupidity. Such widespread and persistent political ignorance and irrationality strengthens the case for limiting and decentralizing the power of government….
Political ignorance in America is deep and widespread. The current government shutdown fight provides some good examples. Although Obamacare is at the center of that fight and much other recent political controversy, 44% percent of the public do not even realize it is still the law. Some 80 percent, according to a recent Kaiser survey, say they have heard “nothing at all” or “only a little” about the controversial insurance exchanges that are a major part of the law….
Some people react to data like the above by thinking that the voters must be stupid. Butpolitical ignorance is actually rational for most of the public, including most smart people. If your only reason to follow politics is to be a better voter, that turns out not be much of a reason at all. That is because there is very little chance that your vote will actually make a difference to the outcome of an election (about 1 in 60 million in a presidential race, for example).2 For most of us, it is rational to devote very little time to learning about politics, and instead focus on other activities that are more interesting or more likely to be useful. As former British Prime Minister Tony Blair puts it, “[t]he single hardest thing for a practising politician to understand is that most people, most of the time, don’t give politics a first thought all day long. Or if they do, it is with a sigh…. before going back to worrying about the kids, the parents, the mortgage, the boss, their friends, their weight, their health, sex and rock ‘n’ roll.”3 Most people don’t precisely calculate the odds that their vote will make a difference. But they probably have an intuitive sense that the chances are very small, and act accordingly.
In the book, I also consider why many rationally ignorant people often still bother to vote.4 The key factor is that voting is a lot cheaper and less time-consuming than studying political issues. For many, it is rational to take the time to vote, but without learning much about the issues at stake….
Political ignorance is far from the only factor that must be considered in deciding the appropriate size, scope, and centralization of government. For example, some large-scale issues, such as global warming, are simply too big to be effectively addressed by lower-level governments or private organizations. Democracy and Political Ignorance is not a complete theory of the proper role of government in society. But it does suggest that the problem of political ignorance should lead us to limit and decentralize government more than we would otherwise.”
