"And so they're absolved of not only the work, but of learning that work has to be done and that each one of us must contribute for the betterment of the whole," she said.
Lythcott-Haims believes kids raised on chores go on to become employees who collaborate well with their co - workers, are more empathetic because they know first - hand what struggling looks like, and are able to take on tasks independently.
She bases this on the Harvard Grant Study, the longest longitudinal study ever conducted.
"By making them do chores — taking out the garbage, doing their own laundry — they realize I have to do the work of life in order to be part of life," she tells Tech Insider.
2. They teach their kids social skills.
Researchers from Pennsylvania State University and Duke University tracked more than 700 children from across the US between kindergarten and age 25 and found a significant correlation between their social skills as kindergartners and their success as adults two decades later.
The 20-year study showed that socially competent children who could cooperate with their peers without prompting, be helpful to others, understand their feelings, and resolve problems on their own, were far more likely to earn a college degree and have a full-time job by age 25 than those with limited social skills.
Those with limited social skills also had a higher chance of getting arrested, binge drinking, and applying for public housing.
"This study shows that helping children develop social and emotional skills is one of the most important things we can do to prepare them for a healthy future," said Kristin Schubert, program director at the Robert Wood Johnson Foundation, which funded the research, in a release.
"From an early age, these skills can determine whether a child goes to college or prison, and whether they end up employed or addicted."
3. They have high expectations.
Using data from a national survey of 6,600 children born in 2001, University of California at Los Angeles professor Neal Halfon and his colleagues discovered that the expectations parents hold for their kids have a huge effect on attainment.
"Parents who saw college in their child's future seemed to manage their child toward that goal irrespective of their income and other assets," he said in a statement.
The finding came out in standardised tests: 57% of the kids who did the worst were expected to attend college by their parents, while 96% of the kids who did the best were expected to go to college.
This falls in line with another psych finding: the Pygmalion effect, which states "that what one person expects of another can come to serve as a self-fulfilling prophecy."
In the case of kids, they live up to their parents' expectations.
4. They have healthy relationships with each other.
Children in high-conflict families, whether intact or divorced, tend to fare worse than children of parents that get along, according to a University of Illinois study review.
Robert Hughes, Jr., professor and head of the Department of Human and Community Development in the College of ACES at the University of Illinois and study review author, also notes that some studies have found children in non - conflictual single parent families fare better than children in conflictual two-parent families.
The conflict between parents prior to divorce also affects children negatively, while post-divorce conflict has a strong influence on children's adjustment, Hughes says.
One study found that, after divorce, when a father without custody has frequent contact with his kids and there is minimal conflict, children fare better. But when there is conflict, frequent visits from the father are related to poorer adjustment of children.
Yet another study found that 20-somethings who experienced divorce of their parents as children still report pain and distress over their parent's divorce ten years later. Young people who reported high conflict between their parents were far more likely to have feelings of loss and regret.
5. They've attained higher educational levels.
A 2014 study lead by University of Michigan psychologist Sandra Tang found that mothers who finished high school or college were more likely to raise kids that did the same.
Pulling from a group of over 14,000 children who entered kindergarten in 1998 to 2007, the study found that children born to teen mums (18 years old or younger) were less likely to finish high school or go to college than their counterparts.
Aspiration is at least partially responsible. In a 2009 longitudinal study of 856 people in semirural New York, Bowling Green State University psychologist Eric Dubow found that "parents' educational level when the child was 8 years old significantly predicted educational and occupational success for the child 40 years later."
6. They teach their kids math early on.
A 2007 meta-analysis of 35,000 preschoolers across the US, Canada, and England found that developing math skills early can turn into a huge advantage.
"The paramount importance of early math skills — of beginning school with a knowledge of numbers, number order, and other rudimentary math concepts
