• Survey

Surveys are sometimes used to assess preferences towards policy issues that are remote from experience and that have never been publicly discussed. How do these preferences of isolated survey respondents compare with preferences expressed by voters who have access to advice from competing political parties? I address this question by conducting a field experiment with a sample of the general public in which I experimentally control the subjects' access to the actual positions of competing parties and interest groups on specific novel policy propositions. Access to party positions decreased approval of the proposed environmental policy among right-wing voters by over fifty percent, and this effect was similar for different educational groups. When voters had access to party positions, their policy preferences were more consistent with their general political orientation. I conclude by discussing implications of these results for the debate about voter competence and for preference elicitation using surveys.
