Why Are Voters So Uninformed?

Surveys routinely show that the general public is poorly informed about government and politics. In a survey conducted in 2010, for example, fewer than half of respondents even knew which political party held the majority of the seats in the House of Representatives. Professor Diana Thomas asks why the public knows and cares so little.

To answer, she draws upon an argument from Professor Anthony Downs. He claimed that it is actually rational for people to be ignorant about politics because the act of voting itself is irrational. One voter is unlikely to influence an election or lead to improvements in government performance.

Informed voters may put a lot of time and energy into researching the best candidates and understanding the issues in government. For this work, they receive little reward since the chance their votes will change the outcome of an election are virtually zero. In other words, people don’t take the time to be informed because there is little incentive to do so. For this reason, many economists will say it is completely rational to be ignorant about politics.

You’ve probably seen surveys that show how uninformed the general public is about government and politics. For example, in a survey conducted by the Pew Research Center in 2010, only 46 percent of respondents knew what party held the majority in the House of Representatives. Worse, only 39 percent knew that national defense is the biggest government budget item, and only 14 percent knew roughly what the current inflation rate was.

The usual response to statistics like these is frustration and calls for better civic education. But maybe there are other factors to blame. Have you ever wondered why the public knows and cares so little? Economist Anthony Downs argued that it’s actually rational to be ignorant about politics because the act of voting itself is irrational.

His argument goes as follows: The costs of being an informed voter are relatively high. You have to follow the news by either reading a paper, reading online, or maybe watching the news. Ideally, to be well informed, you do all of those things. If we value the time it takes you to get informed at your hourly wage, this can get expensive pretty quickly. On a practical level, becoming an informed voter is competing with a lot of other demands on your time.

And what about the benefits of voting? Well, you might think that the benefit of being an informed voter is better government performance. But that is false and here’s why: Just because you’re better informed doesn’t mean that politicians will do a better job. As a voter, you can only affect their actions if your vote changes the result of an election. But the probability that your vote will change the outcome of an election is, for all practical purposes, zero—even in close elections. In other words, people don’t take the time to become better informed because there is a fundamental incentive problem. This is why many economists will tell you it’s completely rational to be ignorant about politics.

    I love the animation of the ballot paper plane hitting the politician. This is perhaps the perfect way of getting people to understand what their vote means.

    However, does rational ignorance apply at the local level, where one has a greater influence?

  2. taschrant

    I would think that rational ignorance at a local level would be less significant when compared to the federal level.  It’s a person’s immediate community.  I could be wrong though.

  3. EnsenLux

    If history has repeatedly shown that the majority can often be wrong, where’s the legitimacy of voting?

  4. Steve Davies

    I can attest to the high cost. I still think I’m better off being better informed.

  5. Gavin Moore

    because the alternatives are horrific. democracy is the least worst system of gov

    If you are completely ignorant and make a choice based on flipping a coin, you a least have a 50/50 (assuming two candidate/options) of being “correct”.  If you go for information, you have a chance of being misinformed and therefore increase your chance of the wrong decision.


    Give me some dice, I am going voting.
