Where does legal doctrine come from? Theoretical and qualitative empirical research has suggested that the Courts of Appeals develop doctrine that the Supreme Court then adopts, but no systematic evidence of this yet exists. In this paper, I use computerized text analysis to explore how arguments move from the Courts of Appeals to the Supreme Court and back down again. Using the text of all opinions from the Supreme Court and the U.S. Courts of Appeals, I apply the techniques from Bayesian topic modeling to case law. I quantify Supreme Court opinions as amalgams of Courts of Appeals opinions.
Results clearly show that the Courts of Appeals develop doctrine that is then adopted by the Supreme Court, and that this adoption is strategic. I then quantify changes in language use by the Courts of Appeals to show the impact of a Supreme Court opinion.
