Marking Supreme Court justices on a 2-pole scale does not accurately represent the complexity of their individual voting records.
Looking at the split between Gorsuch and Kavanaugh is a particularly interesting part of this look at the voting record of the court...
Yes but in theory all political positions and decisions are subject to this "complexity". Not all (R)'s or (D)'s are going to vote the same. I'd argue it's better in America because you don't have a party whip whipping eachother into line, although there are other means of getting everyone on the same page.
True, but the Supreme Court isn't arguing the merits of policy. They are reading the exact same documents and coming up with different rulings due to their individual interpretation of the scope and meaning of the source documents. Gorsuch and Kavanaugh are absolutely far right conservatives, and yet have come down on opposite sides of rulings because of how they see law: Codified and inviolate, or mutable over time. The entire basis of the article is that journalists do a disservice to the multiple dimensions the Supremes work on, when they use a bipolar measurement like Conservative vs Liberal. That's entirely different than politics or the motivators for politicians and their parties.
