On this week's episode of Radiolab, they played a clip of an experimenter asking children about ethical questions. He asked "If there wasn't a rule not to hit someone, would it be OK then?" Even little children (I think 4 years old) knew it wasn't.
It made me think of those stupid AT&T commercials like this one. Knowing how wise children really are makes it even worse to trivialize it when selling mobile phone service.
