This research chapter uses natural language processing and computational text analysis to examine Supreme Court opinions as crucial data for understanding legal thought evolution, focusing on two areas: analyzing trends in judicial writing style through sentiment analysis and stylometry, and comparing Supreme Court content to lower federal appellate courts to determine if the Court has developed a distinctive judicial genre.

Underdevelopment Despite Upzoning

This paper challenges the common assumption that restrictive zoning regulations are the primary constraint limiting housing supply and increasing costs. Through a case study of Charlottesville, Virginia, the research reveals significant underdevelopment of parcels even under current zoning classifications, suggesting that many properties remain untapped despite being zoned for additional housing units.

An Expert-Sourced Measure of Judicial Ideology

This paper introduces JuDJIS (Jurist-Derived Judicial Ideology Scores), the first dynamic method for measuring federal judges' ideologies using computational text analysis of over 20,000 written evaluations from an ongoing survey of jurists since 1985. The method significantly outperforms existing static measures like the Judicial Common Space in predicting case outcomes and could enable new breakthroughs in courts research that were previously impossible due to data limitations.
