Abstract

A l’occasion du premier tour des élections présidentielles du 22 avril 2012, les électeurs de trois communes françaises ont été invités à tester in situ le vote par approbation ainsi que trois versions du vote par évaluation. Ce papier a pour objet de présenter les résultats de cette expérimentation. Après correction des biais de représentativité locaux et nationaux, deux enseignements principaux s’en dégagent. Le vote par approbation conduit à un classement des candidats qui diffère nettement du scrutin uninominal et, quelle que soit l’échelle des notes retenue, le vote par évaluation tend à accentuer cette divergence.
