Chapitre d'ouvrage: This paper is a survey of what we learned from experiments about how innovations in the field of voting are received. Different experimental methods have been used: in the laboratory, on line and in situ. Preferences for voting rules are driven by self-interest, by a quest for simplicity and are also correlated with political attitudes. For most rules, voters show no cognitive barriers to their use, but for more complex rules, serious misunderstanding can appear.
