To your point on 1) regarding the individual, I think the memo author's original point may have been too inconspicuous "...so you can’t say anything about an individual given these population level distributions." I agree with the flaws in projecting stats to any given individual. That point about equilibrium is very interesting; makes me wonder about civilization fitness and competitiveness for those that discover the natural equilibriums and exploit them to their advantage. Sort of like a Star Trek Next Generation episode where some planet's society was able to measure all the traits in their children and direct them to where they were optimized. Makes me want to dig up that old plotline and see what the writer's thought about such a ordering of society.
