Ostrogorski Paradox
Updated 2026-08-09
INTRODUCTION
English translation pending.
CORE DEFINITION
Named after Moisei Ostrogorski, the paradox arises in multi-issue elections where voters choose a party's entire program as a package rather than voting on each issue separately. A party can therefore hold majority opposition on every individual policy and still win the overall vote, because opposing majorities on each issue are formed by different coalitions of voters. The result exposes a mathematical distortion of popular will in representative democracy, and it applies equally to commercial bundles, where a user buys software containing many disliked features by compromising on core ones.
SCAFFOLDING EFFECT
Reduce cognitive load
- Detect bundle distortion: check whether overall support reflects majority views on each component of a package. - Unbundle before deciding: decompose a proposal into separate issues and vote on each independently. - Audit coalitions: map which voter groups support which item, so cross-issue majorities become visible.
Anchor fast decisions
The paradox arises because aggregation is performed over bundled packages rather than single issues. Majorities are recomputed at each policy separately by different voter subsets, so a party can lose every issue-specific majority while its coalition, assembled across issues, remains the largest single bloc. Changing the aggregation dimension flips the majority verdict.
