I've never heard of such a rule either. And, there certainly is an influence of rearing on behavior. If there wasn't, scientists wouldn't go to such great lengths to cross-foster rats to elimate that bias of maternal interactions/rearing in behavior experiments. Why on earth would other environment be so influential and family environment not be? It doesn't even make sense.
