I agree that we shouldn't pigeon-hole children, but they do find their niches, regardless. Personally, as a father, I think the more interesting application of data like this (if true, I tend to wonder about the order of causality as well) would be around how can I get my child out of their comfort zone. This is not shouting at my timid child, it is exposing the highly methodical child to free-form creative activities. Also, coming from a family with a history of substance abuse problems, knowing that a child had a particular predisposition towards abuse would be useless without a solid way to do something about it. Otherwise, it just becomes yet another thing a parent needs to fear and become over protective about.
