Abstract: We argue that perceptions of the U.S. Supreme Court can be influenced by stimuli paired with state courts. People with low levels of court knowledge will exhibit an assimilation effect in which residing in a state with an elected supreme court increases perceptions of the Court being political. People with greater knowledge will demonstrate a contrast effect, meaning that the Court will be perceived as less political compared to an elected state court. Using existing survey data and a new survey experiment, we find evidence of the assimilation effect for low-knowledge participants. Our results imply that fundamental perceptions of the Supreme Court can be shaped by stimuli that are objectively unconnected to the Court, and that many people do not effectively differentiate between different types of court.
