This project performs a custom sentiment analysis of Justice John Paul Stevens' authored concurring and dissenting opinions on the U.S. Supreme Court between 1976 to 1980. Opinions are scored across six emotional categories: Belonging, Liberty, Empathy, Control, Contentment, and Discontentment. Analysis aims to model some of the framework established by Sears, Lapidus and Cozzens (1978) "Content Analysis of Mark Twain's Novels and Letters as a Biographical Method", to understand the correlation between emotional experience and judicial decision making in a political psychology study.
