Because non-voters are less politically informed than voters, some propose that increasing voter turnout would reduce the quality of information among the active voting population, damaging electoral outcomes. However, this argument incorrectly assumes information levels are fixed. This paper demonstrates that information is endogenous to participation. Encouraging individuals to vote motivates those individuals to acquire more political information. As such, the proposed tradeoff between increased participation and informed participation is a false dichotomy. The results further suggest that institutions that make voting more costly cause the population to become less informed; whereas institutions that encourage participation not only increase voter turnout – mobilizing electoral participation also motivates citizens to become more politically informed. A field experiment integrates an intensive mobilization treatment into a panel survey conducted before and after a city-wide election. The results suggest that subjects who were mobilized to vote became more informed about the content of the election.
