In this article, the authors perform a large scale analysis to determine the effects of “robocalling” on voter turnout. The authors determine that turnout increases only marginally when civic duty is primed, but increases significantly when social pressure is applied to establish a norm of civic duty. The authors therefore surmise that “robocalling” is wholly unable to affect voter turnout, which contrasts with critics’ charge that automated political telephone calls drive down voter participation. They conclude that, in order to affect voter turnout, exterior pressures from social norms would have to exist.
