Research Says: Your Mom Influenced Your Intelligence
No surprises here.
Were you the kind of kid who always aced math tests, could memorize historical facts with ease, and recite Shakespeare back to your English teacher like it was a piece of cake? Well then, it’s time to thank your mother, because according to research, she had a lot to do with your intellectual well-being.
In a post, Psychology Spot rounded up a few different research reports which hypothesize that human intelligence can be found in genes that reside in X chromosomes. And, because women have two X chromosomes children are twice as likely to get their intelligence from their mothers.
Moreover, it appears as though a mother’s intelligence gene may even cancel out the father’s.
"If that same gene is inherited from the father, it is deactivated," Psychology Spot explained. "Obviously, other genes work the opposite, are activated only if they come from the father."
For further statistical evidence, Psychology spot pointed out longitudinal study by researchers at the Medical Research Council Social and Public Health Sciences Unit in Glasgow, Scotland. For their research, the group interviewed 12,686 people ranging in age from 14 to 22 who were interviewed annually from 1994 to 2004. After the researchers looked at the participant children’s IQ, race, education, whether or not their mother breast fed them, and their socio-economic status, they found that the best predictor for intelligence was their mother’s IQ.
But, as we all know, intelligence is formed by a lot more than genetics.
“A lot of the research cited in the article claims to show that children’s intelligence is more closely correlated with that of their mother than their father. Well, duh. So long as mothers are the primary caregivers, they are also the primary architects of their child’s environment during the period of critical brain development,” Drew Smith, former R&D director at MicroPhage and SomaLogic, explained on Quora, further explaining the importance of nature vs. nurture. “Of course smart mothers tend to raise smart children. Raising children to be good problem solvers is itself a problem to be solved, and mothers with better brains are likely to do a better job of it.”
