Step Right Up: I’m a Voter and a Lab-Rat
If you shared Facebook’s “I’m A Voter” app in a recent election, you might have become a nice data point for the social media giant and a couple of resourceful political scientists. In the 2010 midterms, the graphic was pinned to 61 million newsfeeds and it turned out that users who saw that their friends were voting were .4 percent more likely to vote than those in the control group (the people without the app). Apparently, this social pressure added 340,000 new voters to the 2010 election cycle.
