A more civil Term?
As we have now well documented, there has long been a gender imbalance in the rate of interruptions of female justices versus male justices. Previously, we asked whether that imbalance had improved in response to the attention being given to the Virginia Law Review article that revealed this pattern, as both Justice Sotomayor and Justice Ginsburg had each suggested it had. As of OT2017, we found that it had not. But an analysis of justice to justice interruptions from the 2018 Term suggests there has been improvement at the Court.
Female Justices are still disproportionately interrupted, but less so
The next two figures are based on our calculation of the normalized rate of interruption for the male and female justices, per argument. Given that Justice Thomas is virtually silent at oral argument and in light of the fact that a number of arguments in the 2018 Term took place before an eight-person bench, it is important to normalize the rate of interruption by the gender ratio of the participating justices in each case. For example, where Justice Ginsburg was absent and Justice Thomas was silent, we treated the Court as comprised of two women and five men. We went back and applied the same methodology to the oral arguments transcripts for previous terms, going back to 1998.
The figure immediately below shows the difference in the normalized rate of interruption for the female justices compared to male justices (orange bars). All bars that appear above the zero line mean that women are interrupted more than men; bars below the line show the reverse. Adjusting for their relative numbers on the Bench, the female justices were interrupted at a higher rate than the male justices in every Term except for 2004 and 2005. What is more, that difference was growing on average from 2006 to 2017. But the 2018 Term shows an improvement.
The 2018 Term was not only less gender imbalanced than the extraordinary 2017 Term, the gender difference was also somewhat lower than in every Term since 2011. Perhaps the change that Justice Sotomayor perceived, of an improved and more civil environment at oral argument, is now manifesting more clearly?
A recent improvement, or a broader trend?
However, the difference in the normalized rate of interruption may be less informative than the same information looked at as a ratio of interruptions between men and women. The figure below shows the ratio of interruptions of female versus male justices (blue bars): a Term measuring at 1 would have an equal number of interruptions of female justices and male justices, normalized by their respective numbers on the Court.
Looked at in this way, not only is the 2018 Term a vast improvement on recent years, it has a lower gender imbalance than any Term since 2004, back when Justice Ginsburg was the sole woman on the Court. It also suggests that perhaps our pessimism last year was unwarranted: this shows that in terms of the ratio of interruptions, female to male interruptions also dropped significantly in 2017, after the issue became one of public comment.
A more civil Court?
Although the difference in the normalized rate of interruption between female and male justices (orange) went up in the 2017 Term and down in the 2018 Term, the ratio of those same numbers (blue) went down in each of those terms. What explains this difference between the orange bars and the blue bars? The answer is that the number of justice to justice interruptions is not constant, not by any means, as the next figure shows.
The 2018 Term was not only a less gender imbalanced term in terms of interruptions, it was also seemingly more civil (or at least less heated) than the 2017 Term. The rate of interruptions in 2017 was exceptionally high, and 2018 saw interruptions drop somewhat. We do not want to overstate the civility that represents: 2018 still saw the third highest level of interruptions in the last 20 years, but the increase over previous years is more in line with a general linear trend, rather than the exponential shift that could have been inferred from last Term’s interruption levels.
We also have to be wary of reading too much into the lower rate of justice to justice interruptions in the 2018 Term. The decrease in interruptions might simply be attributable to the large number of cases where at least one justice was absent—Justice Ginsburg through illness and Justice Kavanaugh by joining the Court partly through the Term. In the next post we will break down interruptions by justice.
One final point to note: remember that the 2004 and 2005 Terms were the only two terms in which men were interrupted more, proportionally, than women. We see from the above figure that those two Terms were also outliers in terms of the number of interruptions. This suggests that even with just one relatively senior woman on the Court, the unusual lack of gender imbalance in those two Terms was seemingly a result of more men being interrupted, rather than women being interrupted less.
Technical note:
When we talk about interruptions in this post, we include any time one speaker interrupts another speaker as indicated in the transcript by the “–” notation at the end of the line. Previously, we have differentiated between quickly occurring interruptions, which may be accidental (called “crossovers” to capture two people beginning to speak at almost the same time), and more distinct interruptions, occurring when a speaker clearly has the floor, capturing more explicitly impolite or deliberate interruptions. We do not yet have the timestamps for this Term to make this distinction. Consequently, there may well be instances where the transcript reflects an interruption which some of our readers may feel was not “really” an interruption. That may be so, however, readers should also consider that perceptions of whether one speaker has interrupted another are affected by the biases and expectations of the listener and we trust the court reporters to at least be consistent. We have used the same definition of interruption in all of the data in this post.
