Abstract
The Iowa Supreme Court adopted an unpopular but unanimous ruling in Varnum v. Brien, which established same-sex marriage. Using a unique panel study conducted immediately before and after the court decision, we evaluate the impact of policy adoption on changing opinions on minority rights. The signaling of new social norms pressured some respondents to modify their expressed attitudes. We find that respondents whose demographic characteristics would predict support for marriage equality, but previously did not, were more likely to shift their opinions to be consistent with the new state law. A policy feedback mechanism may be responsible for the rapid diffusion of laws legalizing same-sex in the states.
