How they write Measured from 55 of 55 decisions

Every opinion of the Term, read from its PDF and measured by writing: the Court’s opinion, each concurrence and each dissent, body text only (footnotes counted apart, citations counted once each).

Length, by kind of writing

Justice	Opinions of the Court	Concurrences	Dissents
Roberts, C.J.	74,849	35,451	13,413
Thomas	71,998	111,096	74,392
Breyer	63,460	2756	54,692
Alito	64,560	8971	41,136
Sotomayor	62,668	91,279	45,720
Kagan	64,420	11,429	43,368
Gorsuch	64,027	92,660	45,365
Kavanaugh	54,520	7629	27,480
Barrett	32,719	1485	32,769
Per curiam	31,166	—	—

Each cell is the number written, a bar, and the median length in words. The bars share one scale, so a dissent’s length reads against a Court opinion’s: a bar is full at 7,480 words, the longest median among cells with two or more writings, and a longer one is marked. A concurrence in the judgment is counted with the concurrences; a mixed writing with the dissents.

A Justice’s writings of every kind, weighted by length. Each column is shaded from its lowest value (lightest) to its highest (darkest) among the Justices. Across the Term’s 141 writings: 18.1 words per sentence, grade level 11.2, 16.1 citations per 1,000 words. Grade level is Flesch–Kincaid, computed after citations are masked; on legal prose it is an index for comparing Justices, not a reading age.

Who agreed with whom Lineups parsed for 55 of 55 decisions

Every pair of Justices, as a network. A line joins two who ended on the same side of the judgment at least as often as the threshold; the thicker and darker, the more often. Distance is the layout’s reading of the whole matrix: pairs who agree sit close. Circle size is the share of decisions in the majority. The stricter reading counts only decisions where both joined the opinion of the Court in full. Hover a Justice or a line for the numbers.

Share of decisions both took part in where both were on the same side of the judgment. A Justice who concurred in part and dissented in part is on neither side for that decision.

Share of decisions both took part in where both joined the opinion of the Court without a qualifier; a plurality or a split opinion counts for no one.

How these are counted

A decision is one written opinion of the Court in an argued case. Consolidated dockets argued together count once.

A mixed writing counts once, under its lead label, and is marked partial. A concurrence in part and dissent in part is never two writings.

A plurality credits its author with the lead opinion; there is no opinion of the Court to have joined in full.

Partial joins (“joined as to Part II–B”) count as agreement on the judgment but not on the full opinion.

Denominators are per pair: only decisions both Justices took part in, and in which neither was on both sides.

Merits only. Argued cases on the Granted & Noted List. Dissents from denial and emergency-docket writings are not counted here.
