Résumé
Des élections expérimentales faites à Montréal, Paris et Bruxelles permettent de comparer l’influence directe du mode de scrutin sur la décision des électeurs de voter ou non, et de voter pour leur parti préféré ou non. En tout, 16 groupes de 21 électeurs votent sous différents systèmes électoraux, soit le système uninominal à un tour et la représentation proportionnelle. Les préférences sont attribuées aléatoirement et connues de tous les participants. Nos résultats indiquent que le vote n’est pas globalement plus sincère et que la participation électorale n’est pas plus élevée lorsque le nombre de sièges pouvant être remportés augmente. Toutefois, nous observons moins de désertion d’un petit parti sous le système proportionnel.
Abstract
Experimental elections made in Montreal, Paris and Brussels compare the direct influence of the voting system on the voters’ decision whether to vote or not, and vote for their preferred party or another party. In all, 16 groups of 21 voters take part in elections under different electoral systems, that is: simple plurality and proportional representation. Preferences are randomly assigned and known by all participants. Our results indicate that voting is globally not more sincere and that voter turnout is not higher when the number of seats liable to be obtained increases. However, we observe less desertion of small parties under the proportional system.
