Something nobody seems to mention that could be a convoluting factor... I wonder if this operates bidirectionally - if parents learn traits from their offspring, maybe to a lesser extent. If you have a group of people that constantly spend time around each other, they all seem to average out their social tendencies over time, to some degree. As children get older and develop more defined characteristics, it's possible this isn't a one-way street.
