I vote fear.
common sense only gets you so far.
When we were little it was FEAR of getting a spanking (or in trouble) and Fear of that pain from the spanking that kept us from doing something bad in the long run. Yes, common sense was probably the first thing that made us stop and think about it. But, directly after that it was something like "Im gonna get beat so bad I wont be able to sit down for a week."
