No, we're only theoretically smarter. A truly smart human would not get caught. But that makes lousy television, so the humans in zombie shows are dumb. They have to be stupid enough to get themselves into situations where a slow moving shambling mound of meat with no weapon other than teeth and no ability to plan or ambush could be a threat to them. Otherwise there's no show.
So instead of smart humans opening a door to the prison and making noise to draw the zombies out where they can safely be handled one by one the dumb humans go stumbling around in the dark making no attempt to protect themselves from attacks from the rear or either flank.
