What does social pressure research show in simple terms?

When people are told their neighbors will learn whether they voted, many more of them go and vote.

Are there problems with this approach?

The effect is large, but it can feel intrusive or provoke backlash, so gentler methods such as thank-you messages are used more often.

Social Pressure and Turnout

🏛️ Politics & Public Administration By CampusDown Wiki Editorial Team Last updated October 27, 2026

Social pressure and turnout refers to research showing that the social norm of voting as a civic duty, together with the pressure created when others can learn whether one voted, substantially increases participation. Alan Gerber, Donald Green and Christopher Larimer provided strong evidence in 2008 with a field experiment on some 180,000 Michigan households. It is a leading example of participation motives that cannot be explained by the costs and benefits of voting alone.

The neighbors experiment

Gerber, Green and Larimer (2008) randomly sent voters mailers that simply reminded them of their civic duty, told them their turnout was being studied, showed their own household's voting record, or also revealed their neighbors' records. Turnout among households receiving the neighbors mailer rose by about 8 percentage points, far more than conventional mail appeals. This showed that social rewards and sanctions can help answer the paradox of voting.

As in Cialdini, Reno and Kallgren (1990), people tend to act in line with what others do and approve. DellaVigna and colleagues (2017) measured a motive to vote so as to answer 'did you vote?' honestly. Funk (2010) found that when Switzerland introduced mail voting, turnout fell in small communities where people know each other, suggesting that appearing at the polls had been a social signal. Panagopoulos (2011) reported that gentle messages thanking people for past voting also work.

Extensions and limits

Bond and colleagues (2012) showed among 61 million Facebook users that displaying news that friends had voted increased turnout. These findings strongly influenced mobilization strategies and research on habitual voting. Mann (2010), however, tested whether strong pressure messages provoke backlash among some voters, and privacy concerns mean campaigns often use softened versions.
