Kaufman, Kraft & Sen (2019): Improving Supreme Court Forecasting Using Boosted Decision Trees

Boosted decision trees that add what the Justices did at oral argument: whom they questioned, how much, and whom they cut off. We rebuilt the model from the authors' replication archive, checked it on their own data, recomputed their oral-argument variables from the Court's transcripts, and ran it on OT2010–OT2025.

Verdict: reproduced on the authors' data; on later cases the edge mostly disappears. On the authors' own data our rebuild scores 74.5% (paper: 74.0%) and makes the same call as their published predictions on 93.4% of cases. Built from the Court's own transcripts, the paper's design scores 65.4% on OT2010–OT2019 against 63.9% for the petitioner always winning (+1.5 points). Forecasting OT2022–OT2025 one term at a time, it gets 68.6% of 229 cases against 67.2% (+1.4 points, within chance), and in OT2025 it does worse than the baseline.

The study

Question. Does what happens at oral argument (which side the Justices question, how much they talk to each side, whom they interrupt) improve forecasts built from a case's characteristics, and is boosting a good tool for it?

Design. A cross-validated test on cases argued OT2005–OT2014: the model is fit on nine-tenths of the cases and scored on the remaining tenth, ten times over, and compared with "the petitioner always wins" and with earlier models refit on the same cases.

Data

  • 704 argued cases with a clear winner, OT2005–OT2014 (697 scored).
  • Eight case variables from the Supreme Court Database: origin court (by circuit), whether a federal or a state agency acted, the lower court's ideological direction and disposition, issue area, cert reason and jurisdiction.
  • 47 oral-argument variables from the Oyez transcripts, for the five Justices who sat and spoke throughout (Breyer, Ginsburg, Kennedy, Roberts, Scalia): for each, the share of turns spent on each side, how often those turns are questions, which side drew more of their questions, turns and words, and how often they cut a lawyer off mid-sentence; plus which side had more lawyers arguing (usually because the Solicitor General joined it) and the net number of interruptions.

Method

  1. AdaBoost: decision trees are fit one after another, each giving more weight to the cases the earlier ones got wrong, and their votes are combined.
  2. Each step is a forest of shallow (three-level) extremely randomized trees.
  3. Scored by tenfold cross-validation, with the cases kept in docket order.

What they found

ModelNotes
Case variables + oral argument74.04%Against 67.98% for the petitioner always winning (the authors' figure for all cases since 2000): about seven more correct calls a term.
Oral argument only72.5%Most of the gain comes from the argument.
Case variables only60.6%Below the base rate: no model the authors tried beat it with case variables alone.
By kind of case6–3 decisions +13 points; federalism +16; government a party +9Weaker gains in criminal procedure, civil rights and First Amendment cases.

The takeaway. How the Justices behave at argument says more about the outcome than the case's paperwork does; on its own, the paperwork did worse than simply picking the petitioner.

What the authors' code shows

  • The baseline is from a different sample. The paper's 67.98% is the petitioner's win rate in all cases since 2000. In the 697 cases the model was actually scored on, the petitioner won 65.8%, and the authors' published predictions get 73.9%: an edge of +8.0 points on those cases, larger than the 6 points reported.
  • The test is not a forecast. Cross-validation in docket order means that most test cases are predicted by a model trained partly on later terms. That measures fit, not the ability to call next term's cases in advance; we add forward forecasts below.
  • Only five Justices are in the model. The oral-argument variables cover Breyer, Ginsburg, Kennedy, Roberts and Scalia; what Thomas, Alito, Sotomayor and Kagan did at argument is not used.
  • Nothing was tuned. The grid search is given no parameters to search, so the settings in the code are the model: 10,000 boosting rounds of 10,000-tree forests.
  • Codes are used as numbers. The database inputs enter as raw codes (issue area 1 to 14, for example), and code 3 of the lower-court disposition is recoded to 1.5, the same recode the code applies to the lower court's direction.

How we rebuilt it

Check: our model on the authors' own data

The archive includes the authors' finished feature table. We ran our implementation on it, scored it the same way (tenfold, docket order), and matched its calls against their published predictions.

Our rebuild makes the same call as the authors' published predictions on 93.4% of the 697 cases.

The paper's design on a later decade (OT2010–OT2019)

The same variables recomputed from the Court's transcripts for 657 cases, scored by tenfold cross-validation in docket order, as in the paper, with the six Justices who sat and spoke throughout the decade.

InputsAccuracyPetitioner always wins
Case variables + oral argument65.4%63.9%
Oral argument only65.6%63.9%
Case variables only58.1%63.9%

With the five Justices used for forecasting instead (Thomas in place of Ginsburg and Breyer), the same test scores 62.9% (−1.0 points).

The signal underneath: does the side questioned less win?

The best-known regularity in oral argument is that the side the Justices question more tends to lose. In the authors' cases (OT2005–OT2014) the side that drew fewer turns won 62.8% of the time. In ours it won 57.6% in OT2010–OT2019 (629 cases), and 47.6% since OT2020 (328 cases): no better than a coin flip. The change coincides with the Court adding, from OT2020, a round in which each Justice questions each lawyer in turn by seniority, which evens out how many turns each side gets.

Forecasting OT2022–OT2025

Each term predicted by a model trained only on earlier terms (from OT2010), so nothing from the term itself is seen.

Case by case

Each case shows how the five Justices' turns split between the sides, the model's pick (and the pick using the argument alone), and the winner.

What we learned

  • The paper reproduces on its own data. Our implementation scores 74.5% on the authors' feature table (they report 74.04%) and agrees with their published predictions on 93.4% of cases.
  • The edge does not carry over. Recomputed from the Court's transcripts for a later decade, the same design beats the petitioner-wins baseline by +1.5 points, not the 6 to 8 points of the original; forecasting OT2022–OT2025 term by term, by +1.4 points, within chance, and in OT2025 it falls 5.3 points short.
  • The argument still carries more information than the paperwork. As in the paper, case variables alone do worse than the baseline (58.1% on OT2010–OT2019; 63.8% on OT2022–OT2025), and the argument alone does about as well as both together (69.9% on OT2022–OT2025).
  • The format of argument changed. The regularity the model leans on, that the side questioned more tends to lose, held in OT2010–OT2019 (57.6%) but not since the Court added turn-by-turn questioning in OT2020 (47.6%). A model trained on how the Justices used to question will misread how they question now.
  • Data plumbing matters. Our first run, with a transcript parser that only knew the current nine Justices, made the signal look reversed. Fixing it (now in the site's parser) moved our counts into 94% agreement with an independent count of the raw transcripts.

The inputs the OT2025 model leaned on most:

  1. Net interruptions (respondent minus petitioner) 3.7%
  2. Which side had more lawyers arguing 3.6%
  3. Sotomayor: share of turns to the respondent that are questions 2.9%
  4. Sotomayor: share of turns to the petitioner that are questions 2.8%
  5. Lower court's ideological direction 2.7%
  6. Alito: share of turns to the petitioner that are questions 2.5%
  7. Kagan: share of turns to the respondent that are questions 2.4%
  8. Roberts: whom they cut off more 2.4%
  9. Issue area 2.4%
  10. Reason cert was granted 2.3%
