Comment by duffmancd

I think the issue might stem from the fact that (as I read it) the essay is talking about "for the people who are moderate (in the middle of the left/right axis), some are distributed higher on your graph, while some are lower". Which says nothing about "for the people who are distributed higher on the graph, how many are in the middle of the left/right axis". Your graph makes explicit an answer to the second question which the essay avoids. (There is a bit of an implication in the last two paragraphs, but PG is explicit it's only about people he knows).
