Breast feeding, for example, is the only way to guarantee a healthy and intellectually advanced child—unless bottle feeding is the answer. A baby should always be put to sleep on her back—until it is decreed that she should only be put to sleep on her stomach. Eating liver is either a) toxic or b) imperative for brain development. Spare the rod and spoil the child; spank the child and go to jail.Read more at location 2066
Note: CONTRADDIZIONI Edit
Gary Ezzo, who in the Babywise book series endorses an “infant-management strategy” for moms and dads trying to “achieve excellence in parenting,” stresses how important it is to train a baby, early on, to sleep alone through the night. Otherwise, Ezzo warns, sleep deprivation might “negatively impact an infant’s developing central nervous system” and lead to learning disabilities. Advocates of “co-sleeping,” meanwhile, warn that sleeping alone is harmful to a baby’s psyche and that he should be brought into the “family bed.”Read more at location 2071

What about stimulation? In 1983 T. Berry Brazelton wrote that a baby arrives in the world “beautifully prepared for the role of learning about him-or herself and the world all around.” Brazelton favored early, ardent stimulation—an “interactive” child. One hundred years earlier, however, L. Emmett Holt cautioned that a baby is not a “plaything.” There should be “no forcing, no pressure,Read more at location 2075

As Holt explained, a baby should be left to cry for fifteen to thirty minutes a day: “It is the baby’s exercise.”Read more at location 2080

An expert must be bold if he hopes to alchemize his homespun theory into conventional wisdom. His best chance of doing so is to engage the public’s emotions, for emotion is the enemy of rational argument. And as emotions go, one of them—fearRead more at location 2083

The problem is that they are often scared of the wrong things. It’s not their fault, really.Read more at location 2090
Note: LA COLPA DEL GENITORE Edit
Consider the parents of an eight-year-old girl named, say, Molly. Her two best friends, Amy and Imani, each live nearby. Molly’s parents know that Amy’s parents keep a gun in their house, so they have forbidden Molly to play there. Instead, Molly spends a lot of time at Imani’s house, which has a swimming pool in the backyard.Read more at location 2094

But according to the data, their choice isn’t smart at all. In a given year, there is one drowning of a child for every 11,000 residential pools in the United States. (In a country with 6 million pools, this means that roughly 550 children under the age of ten drown each year.) Meanwhile, there is 1 child killed by a gun for every 1 million-plus guns.Read more at location 2097

Sandman’s “control” principle might also explain why most people are more scared of flying in an airplane than driving a car.Read more at location 2110
Note: MACCHINE E AEREI Edit
It is true that many more people die in the United States each year in motor vehicle accidents (roughly forty thousand) than in airplane crashes (fewer than one thousand). But it’s also true that most people spend a lot more time in cars than in airplanes.Read more at location 2120

The per-hour death rate of driving versus flying, however, is about equal.Read more at location 2123
But fear best thrives in the present tense. That is why experts rely on it; in a world that is increasingly impatient with long-term processes, fear is a potent short-term play.Read more at location 2124

The likelihood of any given person being killed in a terrorist attack is far smaller than the likelihood that the same person will clog up his arteries with fatty food and die of heart disease. But a terrorist attack happens now; death by heart disease is some distant, quiet catastrophe. Terrorist acts lie beyond our control; french fries do not.Read more at location 2127

Just as important as the control factor is what Peter Sandman calls the dread factor. Death by terrorist attack (or mad-cow disease) is considered wholly dreadful;Read more at location 2130

“When hazard is high and outrage is low, people underreact,” he says. “And when hazard is low and outrage is high, they overreact.”Read more at location 2136

Swimming pools do not inspire outrage. This is due in part to the familiarity factor. Just as most people spend more time in cars than in airplanes, most of us have a lot more experience swimming in pools than shooting guns.Read more at location 2139

Theirs is a gesture of love, surely, but also a gesture of what might be called obsessive parenting.Read more at location 2148
Note: OBSESSIVE PARENTING Edit
Compare the four hundred lives that a few swimming pool precautions might save to the number of lives saved by far noisier crusades: child-resistant packaging (an estimated fifty lives a year), flame-retardant pajamas (ten lives), keeping children away from airbags in cars (fewer than five young children a year have been killed by airbags since their introduction), and safety drawstrings on children’s clothing (two lives).Read more at location 2152

Clearly, bad parenting matters a great deal. As the link between abortion and crime makes clear, unwanted children—who are disproportionately subject to neglect and abuse—have worse outcomes than children who were eagerly welcomed by their parents.Read more at location 2161
Note: ABORTO DELINQUENZA E CATTIVI GENITORI Edit
A long line of studies, including research into twins who were separated at birth, had already concluded that genes alone are responsible for perhaps 50 percent of a child’s personality and abilities.Read more at location 2164
Note: 50% GENI Edit
These nature-nurture discrepancies were addressed in a 1998 book by a little-known textbook author named Judith Rich Harris. The Nurture Assumption was in effect an attack on obsessive parenting, a book so provocative that it required two subtitles: Why Children Turn Out the Way They Do and Parents Matter Less than You Think and Peers Matter More.Read more at location 2172

Or will they? Parents must matter, you tell yourself. Besides, even if peers exert so much influence on a child, isn’t it the parents who essentially choose a child’s peers? Isn’t that why parents agonize over the right neighborhood, the right school, the right circle of friends?Read more at location 2187
Note: INFLUENZA INDIRETTA Edit
In determining a parent’s influence, which dimension of the child are we measuring: his personality? his school grades? his moral behavior? his creative abilities? his salary as an adult?Read more at location 2190
Note: SPECIFICARE LA PERFORMANCE Edit
Certain facets of a child’s outcome—personality, for instance, or creativity—are not easily measured by data. But school performance is.Read more at location 2212
Note: SCHOOL PERFORMANCE Edit
These data concern school choice, an issue that most people feel strongly about in one direction or another. True believers of school choice argue that their tax dollars buy them the right to send their children to the best school possible. Critics worry that school choice will leave behind the worst students in the worst schools. Still, just about every parent seems to believe that her child will thrive if only he can attend the right school,Read more at location 2214
Note: SCHOOL CHOICE Edit
School choice came early to the Chicago Public School system. That’s because the CPS, like most urban school districts, had a disproportionate number of minority students.Read more at location 2219

In the interest of fairness, the CPS resorted to a lottery. For a researcher, this is a remarkable boon.Read more at location 2230

Why does this happen? That’s a hard, complicated question. But one answer may lie in the fact that the school attended by the typical black child is not the same school attended by the typical white child, and the typical black child goes to a school that is simply…bad.Read more at location 2333

The typical white child in the ECLS study attends a school that is only 6 percent black; the typical black child, meanwhile, attends a school that is about 60 percent black.Read more at location 2337
Note: DENSITÀ NERA Edit
Just how are the black schools bad? Not, interestingly, in the ways that schools are traditionally measured. In terms of class size, teachers’ education, and computer-to-student ratio, the schools attended by blacks and whites are similar. But the typical black student’s school has a far higher rate of troublesome indicators, such as gang problems, nonstudents loitering in front of the school, and lack of PTA funding.Read more at location 2339

White children in these schools also perform poorly. In fact, there is essentially no black-white test score gap within a bad schoolRead more at location 2343

Here now are the eight factors that are strongly correlated with test scores:          The child has highly educated parents.        The child’s parents have high socioeconomic status.        The child’s mother was thirty or older at the time of her first child’s birth.        The child had low birthweight.        The child’s parents speak English in the home.        The child is adopted.        The child’s parents are involved in the PTA.        The child has many books in his home.          And the eight that aren’t:          The child’s family is intact.        The child’s parents recently moved into a better neighborhood.        The child’s mother didn’t work between birth and kindergarten.        The child attended Head Start.        The child’s parents regularly take him to museums.        The child is regularly spanked.        The child frequently watches television.        The child’s parents read to him nearly every day.Read more at location 2380

Socioeconomic status is a strong indicator of success in general—it suggests a higher IQ and more education—and successful parents are more likely to have successful children.Read more at location 2413

Note: IQ DEL GENITORE Edit
But if an adopted child is prone to lower test scores, a spanked child is not. This may seem surprising—not because spanking itself is necessarily detrimental but because, conventionally speaking, spanking is considered an unenlightened practice. We might therefore assume that parents who spank are unenlightened in other ways. Perhaps that isn’t the case at all. Or perhaps there is a different spanking story to be told. Remember, the ECLS survey included direct interviews with the children’s parents. So a parent would have to sit knee to knee with a government researcher and admit to spanking his child. This would suggest that a parent who does so is either unenlightened or—more interestingly—congenitally honest. It may be that honesty is more important to good parenting than spanking is to bad parenting.Read more at location 2457

Matters: The child’s parents are involved in the PTA.        Doesn’t: The child frequently watches television.Read more at location 2464
Note: TELEVISIONI Edit
The ECLS data show no correlation, meanwhile, between a child’s test scores and the amount of television he watches. Despite the conventional wisdom, watching television apparently does not turn a child’s brain to mush. (In Finland, whose education system has been ranked the world’s best, most children do not begin school until age seven but have often learned to read on their own by watching American television with Finnish subtitles.)Read more at location 2468
