I enjoy (somewhat) watching human behavior at airports. When boarding starts, people go crazy - I've never seen 200 people line up to be ushered to an assigned seat that is 2x smaller than their body so they can sit there for 45 minutes before the plane even gets in the air. It would make the most sense to board the plane from front to back. Period. I guess the "big hurry" is to find "space" in the carry on luggage rack? I don't know - it's so strange to me.
