Who Determines A Kid’s Intelligence? Is It True That Older Dads Have Smarter Sons?
What Makes Kids Intelligent? According to research highlighted by Psychology Spot, a child’s intelligence comes from their mother.
Common sense might suggest that children inherit intelligence from both parents. However, the study reports that certain genes operate differently, depending on whether they are from the mother or father. The genes that determine intelligence are located in chromosome X. Since women carry two X chromosomes and men carry only one, children are twice as likely to get their intelligence from their mom. Further, the study concludes that intelligence genes from the father are deactivated.
Back in 1994, researchers at the Medical Research Council Social and Public Health Sciences Unit interviewed 12,686 people ranging in age from 14 to 22. After accounting for the children’s IQ, race, education, and socio-economic status, the best predictor for intelligence was, once again, the mother’s IQ.
Usually, the mother is “the primary architects of their child’s environment during the period of critical brain development,” Forbes says.
But, scientists estimate that only about 40 to 60 percent of intelligence is hereditary and environmental factors also affecting a kid’s intelligence development.
Q: Is It True That Older Dads Have Smarter Sons?
Studies suggest that there might be a positive spin to delayed fatherhood. Science says sons of older dads have an intellectual boost over their peers. A study published in the journal Translational Psychiatry found that boys born to older fathers were more socially awkward and overly intellectual than those born to younger fathers.
The researchers assessed 7,781 12-year-old twins on their nonverbal intelligence, restrictive and receptive behaviors, and social aloofness. Then, their scores were combined to form a “geek index.” Those who ranked the highest on the index had higher IQs, stronger focus levels, and less concern about fitting in with others.
According to the study’s authors, the geekiness trait is partly inherited from the parents and partly due to mutations that occur in the sperm of older fathers.
Science shows that older moms are better parents
A 2016 Danish study found that being an older mom has big upsides both for the child. The study found that older moms have fewer behavioral, social, and emotional problems than children of younger moms.
According to a 2016 study in the European Journal of Developmental Psychology, older moms make better parents.
The average maternal age and the age of getting married has been on the rise in recent years. A 2016 Danish study found that being an older mom has big upsides both for mother and child. The study analyzed surveys taken by 4,741 mothers and their children, and checked in on the kids when they were 7, 11, and 15 years old.
The research found that older moms were less likely to verbally or physically discipline their kids at 7 and 11 compared to younger moms. When the kids were 15, older moms were more likely to discipline them verbally, but not physically. The study also showed that the 7- and 11-year-olds with older moms had fewer behavioral, social, and emotional problems than children of younger moms.
The results of the study suggest that older moms are more likely to offer emotional stability, tolerance, and mental flexibility to their kids and lead to a healthier parenting style. Similar studies consider a mom “older” when she’s over age 35.
Also, there’s evidence that kids of older mothers may be more intelligent. But, of course, there are risks associated with pregnancy at a later age, ranged from a higher risk of premature births, children born with deformities, and miscarriages.

Q: Is it True That Women With Bigger Butts Give Birth To Smarter Kids?
According to a 2010 study from the University of Oxford, big butts result in healthy children because of the high amount of Omega 3 fatty acids, which is a great nutrition for the development of the baby’s brain. High amount of Omega 3 assures a baby’s balanced diet.
According to the Chicago Tribune, scientists assert that women with fat-bottoms are smarter than women with flat-bottoms for the same reason. Evidence shows that the fat content in a mother’s breast milk comes from her lower half of the body, which includes her thighs, buttocks, etc.
The high amount of Omega 3 storage could be the reason why fat-bottomed women seem attractive to men. William Lassek from the University of Pittsburgh even went ahead and published a book titled “Why Women Need Fat.” But, the overall fitness of the body and a balanced diet are important too.
