Unintentional Voter Mobilization: Does Participation in Preelection Surveys Increase Voter Turnout?

Survey researchers have long been concerned with the question of whether participation in preelection surveys increases voter turnout. This article presents findings from three large-scale field experiments conducted during the 2002 general election in Maryland, New York, and Pennsylvania. Unlike early studies, which found that participation in preelection surveys increased voter turnout, this study finds no significant effect. The author argues that the rigorous experimental methodology and large sample size in these three experiments should allay concern that survey participation affects turnout.
