Citizen participation in experiments on voting rules[La participation des citoyens aux expérimentations sur les modes de scrutin]

In Situ experimentations provide opportunities for exchanges between researchers and citizens. This article describes their potential impact on research regarding political studies and voting rules in particular. It comments the citizens perception of these experiments, and which social expectations they raise. It also illustrates two cases for which the active participation of voters made research questions evolve: firstly, the importance of expressive voting for voters, and secondly, the forms and challenges of understanding and explaining voting rules. These cases all uncover the prominence of voters' agency, and draw attention on the need for scientists' axiological neutrality in political studies.
