Is the near/far distinction actually Robin Hanson's? In his OB post about this, he links to an article in Science, but unfortunately it's behind a paywall so it's hard to tell how Robin's comments divide up into (1) stuff clearly present in the original article, (2) Robin's interpretation of stuff in the article, and (3) original contributions from Robin.

R.H., if you're reading this, would you care to comment?
