[email protected]. A QUANTITATIVE ANALYSIS OF WRITING STYLE ON THE U.S. SUPREME COURT KEITH CARLSON MICHAEL A. LIVERMORE DANIEL ROCKMORE ABSTRACT This Article presents the results of a quantitative analysis of writing style for the entire corpus of US Supreme Court decisions. The basis for this analysis is the measure of frequency of function words, which has been found to be a useful “stylistic fingerprint” and which we use as a general proxy for the stylistic features of a text or group of texts. Based on this stylistic fingerprint measure, we examine temporal trends on the Court, verifying that there is a “style of the time” and that contemporaneous Justices are more stylistically similar to their peers than to temporally remote Justices.
