Expressive Voting

INTRODUCTION
English translation pending.
CORE DEFINITION
Expressive voting, developed by Geoffrey Brennan and Loren Lomasky, holds that voters often act to express who they are and what they value rather than to affect the electoral outcome. Because the probability that a single vote is decisive is effectively zero, the instrumental return to voting is negligible, while the expressive return, in standing, solidarity, and anger, remains. The key qualifier is that this does not make voting irrational; it relocates the benefit from outcome to expression.
SCAFFOLDING EFFECT
Reduce cognitive load
- Motive split: Separate what a vote would achieve instrumentally from what it expresses about the voter. - Puzzle solver: Use expressive benefit to explain turnout where the outcome is already certain. - Forecast caution: Expect voting behavior to track identity signals rather than policy performance.
Anchor fast decisions
When the chance of changing the result approaches zero, a cost-benefit calculation should predict abstention, yet turnout persists. The explanation is that the payoff is not the outcome but the act: casting a ballot communicates identity and values to oneself and to others. Because expression is the reward, voters are relatively insensitive to whether their side can win, which is why landslides and safe seats still produce turnout.
