That’s how accurate a new algorithm is at determining which of the Supreme Court Justices wrote an unsigned opinion (referred to as a per curiam). M.I.T.’s William Li designed the algorithm in response to what he felt is a privilege abused by the courts. Li’s design came together by analyzing each justice’s writing style, and testing accuracy using opinions with known authors. As The Atlantic writes, its eerie accuracy could even make a case for robots that are designed to judge in the style of each of the justices.
