Trapped like rats

Scientists attempting to study how humans behave when trying to escape, in order to design safer exit routes from public buildings, have discovered that trapped humans behave a lot like mice. Among the counter-intuitive results of their study: wider doors mean everybody tries to cram through at once and gets stuck, while narrow doors make people form orderly queues. Putting doors close together doesn't work either, since the queue for one will often block the rest.

As usual, humans are a lot more like dumb animals than we choose to believe.
