Martin-Quinn Scores
Website of the Martin-Quinn scores project at the Center for Empirical Research in the Law (CERL) at Washington University School of Law. The Martin-Quinn scores have been developed by Andrew D. Martin (Washington University) and Kevin M. Quinn (Harvard University) to measure judicial ideology and increase understanding of the politics of the Supreme Court. The site provides an introduction to the project, datasets showing the Martin-Quinn scores from October 1937 onwards and guidance on how to replicate this analysis.
