Do Fathers Matter?
What Science Is Telling Us about the Parent We've Overlooked
Paul Raeburn
(Scientific American)
In 2011 administrators at William Flew High School in Memphis, Tenn., came to a disturbing realization. About one in five of its female students was either pregnant or had recently given birth. City officials disputed the exact figures, but they admitted that Frayser had a problem. The president of a local nonprofit aimed at helping girls blamed the disturbing rate of teen pregnancy on television.
She pointed to the MTV shows 16 and Pregnant and Teen Mom. 'So much of our society is sexually oriented,' she said, arguing that the fixation on sex was enticing girls to have unprotected sex earlier and more often. A lot of us might say the same thing. We know that teenagers are impressionable, and the idea that they would be swayed by MTV makes sense.
But psychologists Sarah E. Hill and Danielle J. DelPriore, both at Texas Christian University, took note of a more subtle fact about Tennessee. Nearly one in four households was headed by a single mother. For Hill and DelPriore, that observation was a tip-off that something entirely different was going on. 'Researchers have revealed a robust association between father absence - both physical and psychological - and accelerated reproductive development and sexual risk-taking in daughters,' they wrote in a 2013 paper. You might expect sexual maturation to be deeply inscribed in a teenager's genes and thus not likely to be affected by something as arbitrary and unpredictable as whether or not girls live in the same house as their father. Yet the association is quite clear. The problem comes in trying to explain it. How could a change in a girl's environment - the departure of her father - influence something as central to biology as her reproductive development?
I put that question to Hill. 'When Dad is absent,' she explained, 'it basically provides young girls with a cue about what the future holds in terms of the mating system they are born into.' When a girl's family is disrupted, and her father leaves or is not close to her, she sees her future: men don't stay for long, and her partner might not stick around either. So finding a man requires quick action. The sooner she is ready to have children, the better. She cannot consciously decide to enter puberty earlier, but her biology takes over, subconsciously. 'This would help facilitate what we call, in evolutionary sciences, a faster reproductive strategy,' Hill said.
In contrast, a girl who grows up in a family in which the bond between her parents is more secure and who has a father who lives in the home might well (subconsciously) adopt a slower reproductive strategy. She might conclude that she can take a bit more time to start having children. She can be more thorough in her preparation. 'If you're going to have two invested parents, you're investing more reproductive resources. If the expectation is you are not going to receive these investments, you should shift toward the faster strategy,' Hill explained.
The Missing Link
For a long time, until women began entering the workforce in bigger numbers in the 1960s and 1970s, fathers had a uniquely valuable familial role to play. They brought home the paychecks that housed and fed their families and provided a little extra for dance lessons, Little League uniforms and bicycles for the kids. Although bringing home a paycheck might not seem like the most nurturing thing a parent could do, it was vital: nothing is more devastating to the lives of children than poverty. Keeping children fed, housed and out of poverty was significant.
But was that it? What else could fathers claim to contribute to their children? The record shows that fathers have been widely overlooked in scientific studies. For example, in 2005 psychologist Vicky Phares of the University of South Florida reviewed 514 studies of clinical child and adolescent psychology from the leading psychological journals. Nearly half of them excluded fathers.
The situation has now begun to change. The discovery of the father is one of the most important developments in the study of children and families. Our failure to address the question of fathers' value is more than simply a matter of academic bickering. It is reflected in the shape of the American family. Fathers are disappearing: fewer dads are participating in the lives of their children now than at any time since the U.S. began keeping records. This shift matters because the effects of a missing father can be profound and counterintuitive—as in the age at which a daughter enters puberty.
Daughters at Risk
Yet the links between puberty and a father's presence are just associations. They do not reveal what causes these changes. In the ideal experiment that would answer this question, we would assemble a group of families and randomly assign some of the fathers to abandon their families and others to stay. Obviously, this proposal is not likely to win approval from an ethics board. So what is the next best thing? Hill and DelPriore designed an experiment in which young women - some of them teenagers and others just past their teen years - were asked to write about an incident in which their father supported them and then were encouraged to write about a time he was not there for them. Then they were asked about their attitudes toward sexual behavior. If the researchers' hypothesis was correct, memories of unpleasant father experiences would lead the young women to express more favorable views of risky sexual behavior. Pleasant memories of their fathers should push them in the opposite direction.
And that is what happened. Women became more sexually unrestricted after recalling an incident in which their father was disengaged, Hill explained. Further experiments showed that father disengagement did not change women's views of other kinds of risky behavior; for instance, they were not more likely to ride a bike without a helmet. The effect was limited to sex.
Hill told me that her research rests heavily on work by Bruce J. Ellis of the University of Arizona, who helped to establish the connection between father absence and adverse outcomes for daughters. Ellis calls himself an evolutionary developmental psychologist. He wants to know whether Charles Darwin's theory of natural selection can help explain how children's environments shape their development - precisely the question that came up in Hill's study. His research on fathers began in 1991, with efforts to test an interesting theory. The idea was that early childhood experiences could change the way children later seek their mates. Early experience seems to set the reproductive strategy that girls use later in their lives. This is not true of boys, possibly because they have a different reproductive strategy.
In a series of studies beginning in 1999, he found that when girls had a warm relationship with their fathers and spent a lot of time with them in the first five to seven years of their lives, they had a reduced risk of early puberty, early initiation of sex and teen pregnancy. As Ellis continued this work, however, he became increasingly frustrated. Clearly, the association between fathers and daughters was profound. Yet he could not determine whether the parental behavior caused the consequences he was seeing in the daughters. An alternative was that girls who begin puberty early and engage in risky sexual behavior do so because they inherited certain genes from their parents. Fathers might pass on genes linked to infidelity to their daughters, in whom they could be associated with risky sexual behavior and early puberty. Or something else in the family's environment could be responsible for the changes in their daughters.
Ellis came up with an innovative way to pose the question. He considered families in which divorced parents had two daughters separated by at least five years in age. When the parents divorced, the older sister would have had five more years with a father's consistent presence than the younger sister. If father absence causes early puberty and risky behavior, then the younger daughter should show more of that behavior than her older sibling. Also, genes or the family's environment would not confuse the results, because those would be the same for both daughters. It was close to a naturally occurring experiment, Ellis realized.
Ellis recruited families with two daughters. Some were families in which the parents divorced; others were intact, to be used as a control group. He wanted to answer two questions: Was the age at which girls had their first menstrual period affected by the length of time they spent with a father in the house? And did that age vary depending on how their fathers behaved? The second question was added because fathers with a history of violence, depression, drug abuse or incarceration can affect children's development.
Ellis's suspicions were confirmed. Younger sisters in divorced families had their first periods an average of 11 months earlier than their older sisters - but only in homes in which the men behaved badly as fathers. 'We were surprised to get as big an effect as we did,' Ellis told me. The conclusion was that growing up with emotionally or physically distant fathers in early to middle childhood could be 'a key life transition' that alters sexual development.
The next step Ellis took was to look at whether these circumstances could affect the involvement of girls in risky sexual behavior. This time he turned to Craigslist, a classified advertising Web site, and posted announcements in several cities that began, SISTERS WANTED! The criteria were very specific: he was looking for families with two sisters at least four years apart in age and currently between the ages of 18 and 36. He limited his search to families in which the birth parents separated or divorced when the younger sister was younger than 14 years. Ellis and his colleagues were able to recruit 101 pairs of sisters, some from families in which the parents had divorced and, using a different ad, some whose parents had not.
This time the researchers found that risky sexual behavior was not related to how long daughters lived with their fathers but to what the fathers did in the time they spent with their daughters. 'Girls who grew up with a high-quality father - who spent more time as a high-investing father - showed the lowest level of risky sexual behavior,' Ellis said. 'Their younger sisters, who had less time with him, tended to show the highest level of risky sexual behavior.'
The next question, then, is exactly how do fathers exert this effect on their daughters? One possible explanation, as unlikely as it might seem, is that a father's scent affects his daughters' behavior. Many animals emit pheromones, chemical messengers that can be picked up by others and can alter their behavior. 'There is certainly evidence from animal research, in a number of species, that exposure to the pheromones of unrelated males can accelerate pubertal development and some evidence that exposure to pheromones of a father can slow it down,' Ellis explained.
If the same is true of humans, pheromones could help explain how the presence or absence of fathers affects their daughters - although that remains an untested hypothesis. Some research suggests that women who sleep with a male partner have more regular menstrual cycles, perhaps because of the presence of the male's pheromones.
As we finished our conversation, Ellis brought up something I had been wondering about. What effect does father presence or absence have on sons? He told me that we do not yet know about sons. His hypothesis is that a father's involvement could have a different effect on sons, enhancing a competitive urge and spurring sons to achieve more when they grow up and leave the family.
Warts and All
As parents of teenagers understand, it is often hard to know how to respond to the crises, struggles, school challenges and social difficulties that are a normal part of the passage from childhood to adulthood. What we do matters—but it is so often hard to know what we should do. One key feature of good parenting, however, is to be accepting of teenagers, which again is often easier said than done - especially when they show up with a tattoo or call you from the principal's office.
Ronald P. Rohner of the University of Connecticut has spent some years looking at the consequences for children and teenagers of being either accepted or rejected by their parents. He thinks that parental acceptance influences important aspects of personality. Children who are accepted by their parents are independent and emotionally stable, have strong self-esteem and hold a positive worldview. Those who feel they were rejected show the opposite - hostility, feelings of inadequacy, instability and a negative worldview.
Rohner analyzed data from 36 studies on parental acceptance and rejection and found that they supported his theory. Both maternal and paternal acceptance were associated with these personality characteristics: A father's love and acceptance are, in this regard, at least as important as a mother's love and acceptance. That is not necessarily good news for fathers - it increases the demands on them to get this right. 'The great emphasis on mothers and mothering in America has led to an inappropriate tendency to blame mothers for children's behavior problems and maladjustment when, in fact, fathers are often more implicated than mothers in the development of problems such as these,' Rohner says.
Empathy is another characteristic that we hope teenagers will develop, and fathers seem to have a surprisingly important role here, too. Richard Koestner, a psychologist at McGill University, looked back at 75 men and women who had been part of a study at Yale University in the 1950s, when they were children. When Koestner and his colleagues examined all the factors in the children's lives that might have affected how empathetic they became as adults, one factor dwarfed all others—how much time their fathers spent with them. 'We were amazed to find that how affectionate parents were with their children made no difference in empathy,' Koestner says. 'And we were astounded at how strong the father's influence was.'
Melanie Horn Mallers, a psychologist at California State University, Fullerton, also found that sons who have fond memories of their fathers were more able to handle the day-to-day stresses of adulthood. Around the same time, a team at the University of Toronto put adults in a functional MRI scanner to assess their reactions to their parents' faces. Mothers' faces elicited more activity in several parts of the brain, including some associated with face processing. The faces of fathers, in contrast, elicited activity in the caudate, a structure associated with feelings of love.
The evidence shows that fathers make unique contributions to their children. It emphatically does not show that children in families without fathers in the home are doomed to failure or anything close to that. Although fathers matter, others can help fill that role. We all know children who grew up in difficult circumstances but now live rich and rewarding lives. Not all of them grow up to be the president of the United States, but Barack Obama is an example of what can be achieved by a child who grew up without a father but managed to overcome it.
Fatherhood is about helping children become happy and healthy adults, at ease in the world, and prepared to become fathers (or mothers) themselves. We often say that doing what is best for our kids is the most important thing we do. The new attention to fathers, and the research we have discussed here, should help all of us find our way.

On March 16, 1777, John Adams took a break from his work on the Articles of Confederation to pen a brief missive to his youngest son, 5-year old Thomas. "I believe I must make a physician of you," wrote the Massachusetts delegate to the Second Continental Congress. "There seems to be a propriety in your studying physic, because your great-grandfather, after whom you was named, was of that profession."
While our second president's understanding of his paternal responsibilities may seem strange to us today, until the 1970s - when the sitcom anti-hero Archie Bunker helped debunk the long-reigning paradigm - most Americans viewed the father primarily as an authoritarian provider. The mother, in contrast, was supposed to tend to the emotional needs of children all by her lonesome.
In "Do Fathers Matter? What Science Is Telling Us About the Parent We've Overlooked," Paul Raeburn attempts to redefine fatherhood for the 21st century. A veteran science journalist, he also wrote "Acquainted With the Night: A Father's Quest to Understand Depression and Bipolar Disorder in His Children" (2004), a memoir covering the last few years of his tumultuous first marriage, during which two of his three children became revolving-door psychiatric inpatients.
This harrowing experience left him feeling "like a failure as a father," as in his frank self-assessment, his own impatience and irritability often exacerbated his children's bouts with mental illness. A decade in the making, this sequel of sorts was begun just as Raeburn found a new wife, with whom he has since fathered two boys. Eager to disprove Samuel Johnson's dictum that second marriages reflect the "triumph of hope over experience," Raeburn has a compelling reason to devour the wisdom of the experts. Although this time around he focuses much more on science than on self, Raeburn remains a participatory journalist, who, like the late George Plimpton, is totally immersed in his subject matter.
Over the last century, the literature on parenting has been largely mother-obsessed. The towering figure in the field, British psychiatrist John Bowlby, who has spawned two generations of disciples, formulated his celebrated attachment theory by studying homeless children displaced by World War II. "Maternal Care and Mental Health," his first major book, concluded that a warm bond with the mother was necessary for optimal cognitive and emotional development; of fathers, this neo-Freudian never would say much.
The resulting lacuna has yet to be adequately filled in. As recently as a decade ago, about half of the developmental studies in leading child and adolescent psychology journals excluded fathers, and only 11% focused on them exclusively. While fathers as a group are less involved than ever - in 2010, 27% of children lived apart from their fathers, as opposed to just 10% half a century earlier - they still are from far irrelevant.
Even their absence, as Raeburn stresses, can have an effect. Lamenting that today's most prevalent camps see fathers as either a vestigial social structure or as a panacea, Raeburn seeks a middle ground, based not on emotion but on scientific evidence.
His lively tour through the latest research in biology, ethology, psychology, sociology and neuroscience is intriguing. Who knew that a supportive father who engages in rough-and-tumble play with his children may well boost both their intellectual development as well as their language ability? Likewise, policy-makers might be interested to learn that the absence of a father can lead to both accelerated puberty and increased sexual risk-taking in daughters. Another provocative study, which Raeburn highlights in his chapter on the "male biological clock," concludes that children born to fathers 40 and older face an increased risk of developing both autism and schizophrenia.
Unfortunately, these findings, like most of the others sprinkled throughout the book, are based on associations rather than causes. In contrast, the female biological clock is incontrovertible, connected to the specific genetic abnormality behind Down syndrome.
All told, the science of fatherhood is not quite ready for prime time. More research is needed before a grand synthesizer - some 21st century version of Dr. Spock - can formulate its key principles.
From the scattered personal references that Raeburn coughs up, it is clear that he has enjoyed a much more satisfying run with his two youngest children. But the reason appears to stem less from any insight gained from evolutionary biology than from his own psychological evolution; he has carefully examined his past behavior and made a string of changes. Instead of engaging in a long commute and skipping family dinners, he does all his writing at home; he now considers his consistent presence a sine qua non. Additionally, he has learned to avoid misdirecting his anger toward his children.
One can't help wishing that Raeburn had devoted more space to the particulars of his quotidian life. As America continues to search for a new paradigm for fatherhood, we are all subjects in a massive social science experiment. And the success stories of individual families can be as valuable a source of information as well-crunched data.
