A Mathematician Crunches the Supreme Court’s Numbers

Steve Fesenmaier spotted an Interesting Look At The Supreme Court through the eyes of a mathematician.

The voting pattern of the Rehnquist court over the last nine years “shows that the court acts as if composed of 4.68 ideal justices,” says Dr. Lawrence Sirovich, a mathematician at the Mount Sinai School of Medicine in Manhattan whose day job is figuring out how the visual system works.


By another measure, “the decision space of the Rehnquist court requires only two dimensions for its description,” he writes in the issue of The Proceedings of the National Academy of Sciences being Published today.
