Future Pundit has a post on preschoolers being naturally inclined to think like scientists. In my mini experiment, this turns out to be the case, since it is now quite clear that it was only me who thought that Dd briefly thought that the TV was actually interacting with her. How traduced she feels. I am sorry.
So anyway, for whatever reason, pre-schoolers look spontaneously for good explanations of cause and effect. Guess that'll be why many creationist child beaters don't want their kids carrying on like that then.
