Downs Paradox / Paradox of Voting
Version 1.0.0 · Updated 2026-07-31
CORE DEFINITION
Anthony Downs pointed out that for a rational, self-interested individual, voting is irrational. Because the probability that your single vote changes the election outcome is extremely low (close to zero), but the costs of voting (time, transportation) are real. Therefore, a rational person should choose to 'free ride'.
SCAFFOLDING EFFECT
Reduce cognitive load
Motivation analysis. It explains why participation rates are usually low in both political elections and company annual meeting feedback. To mobilize people to participate, one cannot rely solely on 'rational calculation'; participation must be given additional social meaning (such as the moral satisfaction of 'fulfilling civic duty').
Anchor fast decisions
The Downs Paradox (rational ignorance paradox) refers to: in large elections, the probability of a single vote affecting the outcome is extremely low, and the cost for a rational person to obtain information is high while the benefit is nearly zero. According to rationality, one should be 'rationally ignorant' and not vote, but in reality, voter turnout is not zero. It reveals the contradiction between traditional rational choice theory and actual political participation.
