Does Partisanship Affect Compliance with Government Recommendations?

This article studies the role of partisanship in American’s willingness to follow government recommendations. I combine survey and behavioral data to examine partisans’ vaccination rates during the Bush and Obama administrations. I find that presidential co-partisans are more likely to believe that vaccines are safe and more likely to vaccinate themselves and their children than presidential out-partisans. Depending on the vaccine, presidential co-partisans are 4–10 percentage points more likely to vaccinate than presidential out-partisans. Using causal mediation analysis, I find that this effect is the result of partisans’ differing levels of trust in government. This finding sheds light on the far-reaching role of partisanship in Americans’ interactions with the federal government.
