I just wanted to point out this comment of mine which applies the principles of analysis of variance to an informal model of political opinions and intellectual stances.
I hate it when my best lines are buried within a comment thread. (I also hate that I respond to blog comments rather than doing real work, but that’s another story. One of the good things about blogging for 538, back when I was doing that, was that the comments were soooo bad I just stopped reading them. Commenters here often have something interesting to say.)
P.S. See also here.
