Poked to Vote: Social media and voter participation

January 25, 2013 by Inga Kiderra
The study is Nature’s Sept. 13, 2012 cover.

If you logged into Facebook on Election Day 2012, you may have seen – along with political rants and raves from your friends (and pictures of cats) – a nonpartisan message from Facebook at the top of your newsfeed, urging you to vote or to be a voter. Or, if you happened to be in the control group, you may have seen no voting message from Facebook itself. Either way, if you logged in from the United States, you were part of a project to increase democratic participation, led by UC San Diego's James Fowler.

Fowler, a professor of political science in the Division of Social Sciences and of in the School of Medicine, was following up on the randomized controlled 61-million-person experiment he and colleagues had run on two years earlier, during the U.S. congressional elections of 2010.

The 2010 experiment, published as the Sept. 13, 2012 cover of Nature, estimated that a single Facebook message seen on that Election Day caused about a third of a million more people to show up at the . It confirmed that peer pressure helps get out the vote – and demonstrated that can affect important real-world behavior.

Importantly, it also showed that most of the effect came not from the message itself but through the influence of friends. And not just any friends: Close friends mattered most.

" made all the difference in political mobilization," Fowler said. "It's not the 'I Voted' button, or the lapel sticker we've all seen that gets out the vote. It's the person attached to it."

In the 2012 experiment, Fowler and colleagues, including UC San Diego psychologist Chris Bryan, were exploring what sorts of messages might work best to increase democratic participation. They were also checking whether certain kinds of people are most influential in the process. Stay tuned for results.

Meanwhile, Fowler – recently named one of TechCrunch's "Most Innovative People in Democracy" – is continuing to study social-network effects on a whole host of other behaviors and phenomena. Though his findings have sometimes made the monologues of late-night comedians, Fowler doesn't do his work for chuckles. Rather, he's looking both to advance our basic understanding of human beings – and to inform the policy decisions we make. But if the second book he's now writing – like "Connected," also with Harvard's Nicholas Christakis – lands him another spot on The Colbert Report, he won't complain.
