The bench spoke 1.6× as many words to the petitioner as to the other side. Since OT2017 the side that draws more of the bench’s words has tended to lose, so this argument reads below the usual 70% petitioner win rate.

A Justice’s lean is the chance they vote for the petitioner, from their own word split and the whole bench’s; the small figure is the change from their usual petitioner rate. Click a row to pick out that Justice in the transcript.

About this page. Built from the Court’s own transcript and recording.
- The lean. Backtested leave-one-Term-out on 511 decided arguments (OT2017–OT2025): 72% of outcomes called right against 70.5% for “the petitioner always wins”, with forecast error (Brier score) 0.197 against 0.209. It refines a strong base rate more than it flips calls. Each Justice’s lean: 67.5% of 4,408 votes against 63.4% for their usual rate.
- Words, not questions. Every Justice turn in an advocate’s time counts toward that advocate’s side; amicus time counts for neither. Counting turns adds nothing once words are counted, and the raw rule “more questions loses” does worse than the base rate, because petitioners argue first and have rebuttal.
- Timing. Each line is timed to the recording: speech recognition matched the Court’s audio to its transcript, and its own text is used for nothing but the clock. Click a line to hear it.
