Our parents form the basis for all other attachments we are able to form with people. Our parents form the basis of how humans are able to interact with others.

I certainly disagree with "So if you want to improve the way children behave in school—for instance, by making them more diligent and less disruptive in the classroom", I think most people can see a correlation between poor quality parenting and badly behaved children. Inside or outside the home. This certainly proves it's point when the average family of University (or College) child age is shown demographically. (Assuming that you exclude financial issues).

Parents have far too great an influence over their children to not matter. This research certainly hinges on undermining the whole of attachment theory, and Freud's work on personality types. If parents did not support certain behaviours then they wouldn't develop. I think that this research on it's own represents a narrow minded view of later development, not something which explains how parents shape their children.

Parents do matter because they create who we are today.

There is a good book about why parents matter, that addresses Harris's ideas: Hold on to Your Kids by Gordon Neufeld, a clinical psychologist. See: http://www.gordonneufeld.com/book.php
