Significance Leveraging three unique surveys collected over a decade that ask members of the public about the policy issues before the US Supreme Court, we show how the court stands relative to the public. As we demonstrate, the court has, since 2020, become much more conservative than the public and is now more similar to Republicans in its ideological position on key issues. We also find that members of the public update their beliefs about the court's ideology when its composition and rulings change. Even so, many members of the public currently underestimate the court's conservative leaning, which in turn makes them less likely to support making changes to the institution than they would otherwise.
