If you posted Facebook’s “I voted” sticker on your wall congratulations, you were part of the most recent social experiment being conducted by the social media giant. The goal: Can users be nudged to vote by saturating their news feeds and offering propaganda stickers as rewards? This civic-minded setup has become an Election Day tradition on the website. These buttons, though, have also always been part of experiments. The voting button in 2010, for instance, was part of a study later published as “a 61-million-person experiment in social influence and political mobilization.”
