School shooters usually are sons of divorced — or absent — parents, writes W. Bradford Wilcox. Boys raised by a single mother are almost twice as likely to end up delinquent compared to boys who enjoy good relationships with their father,” he writes.
“Fathers . . . are important for maintaining authority and discipline,” writes sociologist David Popenoe. “And they are important in helping their sons to develop both self-control and feelings of empathy toward others, character traits that are found to be lacking in violent youth.”
Family breakdown is tougher on boys than girls, writes Kay Hymowitz in City Journal. When parents divorce, girls tend to “internalize” their unhappiness, become depressed, while boys act out, becoming more impulsive, aggressive, and “antisocial.” Girls get better after a few years. Boys don’t.
Boys are slower to mature, writes Hymowitz. They need more “civilizing.”
Lone parents tend to have a tougher time providing the predictability and order that help boys become capable students and workers. Poverty undoubtedly worsens the problem: in general, low-income children have poorer “executive function,” such as self-control and cognitive flexibility, than do middle-income children, according to a 2011 study by a group of Berkeley neuropsychologists. But poor children in single-parent families still came out worse in the study than kids with poor married parents. This is probably because unmarried parents tend to break up more frequently, go on to new relationships, sometimes serially, and bring stepparents and half- and step-siblings into their children’s lives.
Low-income single mothers often live in neighborhoods where “gangs have replaced fathers, the threat of violence looms, and schools are filled with apathetic or hostile males.” Economic mobility tracks marriage, concludes a study by the Equality of Opportunity Project: “Areas with high proportions of single-parent families have less mobility—including for kids whose parents are married. . . . areas with a high proportion of married-couple families improve the lot of all children, including those from single-parent homes.”
Schools can provide structure, time for boys to play rough-and-tumble games and better literacy programs, writes Hymowitz. But it’s not clear what will work for boys growing up without fathers — in places where “fathers — and men more generally — appear superfluous.”
