This study examines the role of information in shaping public opinion in the context of support for education spending. While there is broad public support for increasing government funding for public schools, Americans tend to underestimate what is currently spent. We embed a series of experiments in a nationally representative survey administered in 2012 (n= 2,993) to examine whether informing citizens about current levels of education spending alters public opinion about whether funding should increase. Providing information on per-pupil spending in a respondent’s local school district reduces the probability that he or she will express support for increasing spending by 22 percentage points on average. Informing respondents about state-average teacher salaries similarly depresses support for salary increases. These effects are larger among respondents who underestimate per-pupil spending and teacher salaries by a greater amount, consistent with the idea that the observed changes in opinion are driven, at least in part, by informational effects, as opposed to priming alone.
