Robin Hanson links to a video on student opinions regarding redistribution of GPA scores. I would not be in favor, even though I am sure the ancient Athenians must have worked out some pretty cool defense of that too. Go watch the video, my favorite point of his is this one:
There is only a weak added tendency for students to offer similar opinions and reasons on similar policy questions. Opinions and reasons are not being generated by processes that tend to produce much added similarity.
I am often accused (correctly) of placing too high a value on consistency. It seems Robin does too.
