Online tools like Doodle polls are frequently used for meeting coordination and other decentralized cooperative decision-making. Since Doodle polls are a form of approval voting, theoretical results from voting theory often underpin work in this area. Sincerity, where a voter never says yes to a less-preferred option without saying yes to all more preferable choices, is a common assumption in approval voting. However, that does not take into account cooperative behavior sometimes exhibited by users when others’ responses are known. We conduct a user study investigating the extent to which college-student participants in Doodle-style polls were sincere, reporting on responses from one institution.
