"In addition, numerous studies have found that children who live with their fathers are more likely to have good physical and emotional health, to achieve academically, and to avoid drugs, violence, and delinquent behavior"

there is a lot of info on this though. And not saying saying a person growing up without a father or a less than great father cannot exceed and do well. Just looking at the over all info and statistics available it seems there is direct link between fathering and many of the social issues. While there will always be violence as it is natural to a extent a large contributor to overwhelming violence and social issues is the parenting, and most often the fathering. Which for a long time was dismissed as everyone put attention on the mothers being the primary influence (turns out they aren't).
I would like to know if those numerous studies have also controlled for all other possible variables other than father/no father. How much of this effect is due to the fact that single-mothers are more likely to already be poor? Have they controlled for the idea that poverty, and not just the lack of a father, results in increased violent behavior? Do they compare families of the same socio-economic, cultural, and geographical location or are they comparing ANY family that does not include a father? Does "no father" mean simply that the mother and father are not married, or if there is no involvement whatsoever by that father? Perhaps the father lives elsewhere but is still involved in the child's life in a significant way. Is that factor considered? Who paid for all these studies?
I'm not saying these studies are wrong, but whenever someone says "studies show..." it immediately triggers these questions. There is always more to the story than a report about what 'studies say...'

responsibility and understanding the underlying causes of a pattern of behavior can help change that behavior. If you're constantly bleeding from your ears, do you want to just simply keep putting cotton in your ears to sop up the blood, or do you go to a doctor to figure out why you're bleeding so you can, you know, STOP BLEEDING.
