U.S. Supreme Court justices direct their humorous quips and barbs most often at advocates with whom they disagree, lawyers who are losing their arguments and attorneys who do not have experience at the high court, according to an exhaustive new study.

In their study “Taking Laughter Seriously at the Supreme Court,” two scholars—Tonja Jacobi of Northwestern University School of Law and Matthew Sag of Loyola University of Chicago Law School—built and analyzed a database of every Supreme Court oral argument transcript from 1955 to 2017.
