" The strongest evidence yet was published in 2010. In a painstaking long-term study, much larger and more thorough than anything done previously, an international team of researchers tracked one thousand children in New Zealand from birth until the age of thirty-two. Each child’s self-control was rated in a variety of ways (through observations by researchers as well as in reports of problems from parents, teachers, and the children themselves). This produced an especially reliable measure of children’s self-control, and the researchers were able to check it against an extraordinarily wide array of outcomes through adolescence and into adulthood. The children with high self-control grew up into adults who had better physical health, including lower rates of obesity, fewer sexually transmitted diseases, and even healthier teeth. (Apparently, good self-control includes brushing and flossing.) Self-control was irrelevant to adult depression, but its lack made people more prone to alcohol and drug problems. The children with poor self-control tended to wind up poorer financially. They worked in relatively low-paying jobs, had little money in the bank, and were less likely to own a home or have money set aside for retirement. They also grew up to have more children being raised in single-parent households, presumably because they had a harder time adapting to the discipline required for a long-term relationship. The children with good self-control were much more likely to wind up in a stable marriage and raise children in a two-parent home. Last, but certainly not least, the children with poor self-control were more likely to end up in prison. Among those with the lowest levels of self-control, more than 40 percent had a criminal conviction by the age of thirty-two, compared with just 12 percent of the people who had been toward the high end of the self-control distribution in their youth.

" Long before children can read rules or do chores, they can start learning self-control. Ask any parent who has survived the ordeal of Ferberization, which is based on a technique found in a Victorian child-rearing manual. It requires the parents, against all instinct, to ignore their infants’ cries when they’re left alone at bedtime. Instead of rushing to the infant’s side, the parents let the infant cry for a fixed interval of time, then go offer some comfort, then withdraw for another fixed interval. The process is repeated until the child learns to control the crying and go to sleep without any help from the parents. It requires great self-control by the parents to ignore the heart-rending screams, but the infants usually learn quickly to put themselves to sleep without any crying. Once an infant acquires this self-control, everyone wins: The infant is no longer anxious at bedtime or when he or she wakes up alone in the middle of the night, and the parents don’t have to spend their nights hovering by the crib.

" Nearly all experts agree that children need and want clear rules, and that being held accountable for obeying the rules is a vital feature of healthy development. But rules are helpful only if children know them and understand them, so the brighter the line, the better. Nanny Debs likes to call a special meeting to go over her “house rules,” and then she posts a chore list in each child’s bedroom along with a wooden pole that’s used for keeping score. When children make the bed or clean their rooms or wash the dishes, they get to put a colored ring around the pole. Each ring entitles them to fifteen minutes of watching television or playing a video game, up to a total of an hour per day. If they misbehave, they first get a warning, and if they persist, the parent removes one of the rings. To keep the rules consistent, parents need to coordinate with each other and with caretakers so that everyone knows what’s expected. When your children are still toddlers, establish a system of rewards and punishments in advance, and when you’re giving either one to a child, explain exactly why. As they get older, it becomes more useful to ask them what goals they have for themselves. Once you hear their ambitions, you can help get there with the right incentives, like making allowance payments contingent on doing chores, or promising bonuses for doing extra work. "

" Then, seemingly as an afterthought, the experimenter gave the bowl of M&M’s back to the person and said, “You’re the last subject we have today, and everyone else is gone, so these are left over. Help yourself.” The experimenter exited, leaving the participant alone to fill out the questionnaire and eat his or her fill, apparently without anyone watching or caring. But, as usual, the researchers cared very much. They had weighed the bowl beforehand, and weighed it once again after the participant left. "
