The Philosophy of Democracy and the Epistemic Competence of Citizens
Quick fact
Political scientist Ilya Somin estimates that the median voter knows less about politics than the average non-voter, and that widespread political ignorance is rational because a single vote almost never changes an election outcome.
Why this is interesting
Democracy gives every citizen an equal vote, but what if those votes are cast in ignorance? Can a system of rule by the people actually be wise?

Understanding The Philosophy of Democracy and the Epistemic Competence of Citizens
We often assume that democracy works because citizens are informed and engage in reasoned debate. But a large body of research shows that most citizens are poorly informed about politics—they cannot name their representatives, do not know basic policy facts, and rely on biases. This seems to undermine the very foundation of democracy. However, some philosophers argue that democracy still works, even with ignorant voters. They point to the 'miracle of aggregation': the idea that when many people vote, their individual errors cancel out, and the collective decision can be remarkably intelligent. This is similar to how a crowd's average guess can be very close to the true answer. The tension between these two views—that citizens are incompetent versus that democracy is still wise—lies at the heart of the philosophy of democracy and epistemic competence.
A deeper explanation
The philosophical debate about the epistemic competence of citizens is about whether democracy produces good decisions, not just legitimate ones. Historically, thinkers like Jean-Jacques Rousseau believed that the 'general will' would be correct if citizens were virtuous and informed. But modern critics, starting with Joseph Schumpeter, argued that voters are irrational and easily manipulated, making democracy more a method for selecting leaders than a way to find truth. The strongest epistemic defense of democracy comes from the Condorcet jury theorem: if each voter has a better-than-chance probability of making the correct decision, then the majority's probability of being correct increases with the number of voters. This suggests that even a modest level of individual competence can lead to collective wisdom. However, this theorem relies on conditions that are often violated—voters are not independent, and they can be systematically biased. A more robust epistemic argument is the 'miracle of aggregation' (or the 'diversity trumps ability' theorem): under certain conditions, a group of diverse but uninformed individuals can outperform a group of experts. The key is that errors are random and cancel out, while any signal of truth is amplified. This works for simple judgments, but political decisions are complex and values-laden, making it unclear if such aggregation applies. Given these worries, some philosophers propose 'epistocracy'—the rule of the knowledgeable—suggesting that voting rights be restricted to those who pass a basic political knowledge test. Others advocate for deliberation as a remedy: if citizens discuss issues, they can share information, correct biases, and improve their judgments. This has led to institutions like citizen assemblies, where randomly selected citizens deliberate on issues and often produce well-reasoned recommendations. Ultimately, the philosophy of democracy's epistemic competence is about answering the question: can ordinary people govern themselves wisely? The answer has profound implications for how we design democratic institutions—whether we rely on direct voting, representative government, or more deliberative and expert-guided processes.
