Do You Know What I Know?

Do You Know What I Know? Steven Pinker argues that common knowledge makes the world go round--and off the rails. Take your young kid with you as you commute through Penn Station and you'll find that you have a lot to explain. Walking through the Long Island Railroad concourse, my son was perplexed by the close proximity of three chicken-themed restaurants--Chick-fil-A, Raising Cane's, and Pollo Campero--and by the fact that a shop called Gotham News mainly seemed to sell candy and bottled water. He also wanted to know why some people, as they strolled or waited, drank out of cans in brown paper bags.
