Talking versus Competence

You may have seen this on Instapundit, which is where I first saw it: every male member of the Supreme Court talks less than every female member; all the male members put together talk less than Kentaji Brown Jackson does alone.

It strikes me that the graph ordering them shows an almost perfectly inverse relationship between the quality of the justice and how much that person talks. I think Gorsuch may be better than Kavanaugh, but he talks very slightly more. Otherwise, the relationship holds completely.

Jackson is of course illegitimate, since she was not nominated by a President who was competent to exercise his office.
