The United States Supreme Court has a historical role as a “republican schoolmaster,” inculcating virtues in the citizenry. The role as teacher to the republic also serves the interests of the Court. As the “weakest branch,” the Supreme Court needs public support if its decisions are to be effective. We investigate the Court's ability to win popular support for its rulings, specifically in the case of Roe v. Wade. The analysis shows that the Court's decision did affect public attitudes but not as previous work would predict. While support for abortions to protect health increased as a result of the Court's decision, the public became more polarized over “discretionary” abortions. The puzzle is what process can account for these disparate reactions. We develop a theory resting on interpersonal influences to explain these results, arguing that the social interpretation of events drives the differing outcomes. This theory is then tested against a purely psychological alternative. The closing discussion considers how these results can be extended to the general problem of public decisions and popular responses, including presidential actions and the influence of the media.
