In one experiment, babies aged between six months and a year watched an animated film in which a ball with eyes tries to climb a hill while a square tries to help push it up and a triangle tries to force it back down.
At the end of the film, scientists tested which shape the babies favoured by measuring how long they spent looking at a picture of each one. In 80 per cent of cases, the babies chose the helpful character over the unhelpful one.
Paul Bloom, the psychologist who heads the study team, said: ''Some sense of good and evil seems to be bred in the bone.''
I think it's quite a stretch to say that this experiment in any way showed that babies have a sense of good and evil. At best it showed that babies are attracted to things that help and adverse to things that hinder. I would think that would be a basic instinct shared with any social animal that hopes to survive. To extrapolate morality out of that is going a bit far.
Also, what would lead one to the conclusion that the baby approved of the action because more time was spent watching it? That means nothing unless you can prove that babies approve of actions based on the duration of time they remain fixated on them.
