You think you get altruism from religion? Democracy? Aunt Edna?
The King of the Nerds notes over at The Stranger how waving someone through the intersection (Seattle drivers: GET A CLUE!) is a trait that even lab rats have. Sadly, this causes me to lose a little respect for those cute little rodents. A 500 word article in a free weekly that features a spot titled "Drunk of the Week" right next to the King's is not enough to convince me there is no learned component of altruism. But a weekly science column in a pop culture rag? Now, that's looking out for his fellow man.
