After administering several courses of electric shock, the researchers opened the doors of the cages and then shocked the dogs again. A group of control dogs who had never been shocked before immediately ran away, but the dogs who had earlier been subjected to inescapable shock made no attempt to flee, even when the door was wide open—they just lay there, whimpering and defecating. The mere opportunity to escape does not necessarily make traumatized animals, or people, take the road to freedom.
