Poor nutrition and antisocial behavior

We emphasize genes on this blog, but far be it from me to dismiss the environment as sociologists dismiss genetic influence.  This study shows that even after we control for genes and shared environment, poor nutrition predicts antisocial behavior among children.  So feed your kiddies good stuff.

  3. Good to see you posting again!

    But I have to say if you believe this study, I have a bridge to sell you. :)

    Dietary recall information is one step up from worthless. Time and again it has been shown that what people report they (or in this case, their children) eat has little resemblance to what they actually eat.

    In general, lots of people love the twin control method because they feel they can get answers to "environmental" questions by looking at twins, but in reality it's not much use there. Often the supposed differences between twins is really just measurement error. Further, even if a difference between twins does seem to relate to whatever outcome of interest, that still doesn't mean it was some "environmental" cause, because "identical" twins aren't actually identical.

    Finally, I don't take much behavioral genetic research done on very young children seriously for a variety of reasons.

    Anyways, I look forward to more of your posts!
