    People who pop out kid after kid are short in the smarts department from the start.

      Like Bobby and Ethel Kennedy? No wait, bad example. How about Teddy Roosevelt… oh wait, another bad large family example…

      Just laying the groundwork for “scientific basis” to justify abortions. In the mean time, supporters of the study will die without heirs so that is why they want to take over the education of other people’s kids.

      Several methodological issues with this study. First, it is NOT causal. Only correlational. The pattern could be the result of a third variable. Second, fertility is associated with good health, challenging the hypothesis. Third, the birth rate in Northern Europe is so low that high birth rate women have predisposing factors.

    When you get too old to work and the social security system collapses, having more children is insurance that, at least, one of them can provide for you.

      While also creating more people who will sap the resources of this Social Security, making it run out even faster.

    With the effects of that popular medicine over the past couple of years families are guaranteed to be smaller. Sadly that might mean the absence of a breadwinner or two

    Not necessarily your brain, but bad for your sanity.

    Lived in CentAm 25 yrs+. Those with many kids, are not too smart, not just in mathematics, yet also in basic things. Providing economic assitance to these people, in anyway, 100+ forms now, is a negative for humanity. Rule.

    Good heavens. The author needs to go back to college and take research design and advanced quantitative methods classes. You simply cannot draw CAUSAL relationships from correlational data, no matter what statistical techniques you use. Here is one correction: “The negative effect of having three or more children on cognitive functioning is not negligible, it is equivalent to 6.2 years of aging,” Dr. Bonsang notes. NOT negative effect, negative “association” or negative correlation should be used here. Big difference.

    Who would be stupid enough to believe anything coming out of Columbia? Research? They just shill for whoever is the highest bidder no matter the subject! But then most so called places of “higher education” are little different…Columbia just stands out.

    I have four children. I speak seven languages. My IQ is over 140.
    I think what they meant to say in the article, is that when high IQ people have fewer children, this is bad for the society.

    Modern science at its best, proving what we really want to hear. From a philosophical point of children have always required sacrifice. From career to sanity, yet the “math” all depends on the expectations to begin with. If you plan was to retire and sit around living off your the fruit of your labors, watching the world go by, then this article makes sense. But from a stand point of using your resources to bring human beings into existence and caring for and loving them in all their wonderful messiness, then article reveals the deeper issue at heart. We are selfish and care about our own economic well being than another life. The real math to me is generations down the road when those with two or less children have a small family tree and their children have to find spouses from those having 3 or more. Turns out wisdom has little to do with smarts. Tune in next week for more confusion from “science” on why the birth rate is falling…must be quality of sperm or something.

    Just another article promoting not having kids all while having a picture of a black guy with a white woman again.

    Just a pro abortion slanted study by ultra woke Columbia University

    Correlation vs Causation. Pretty sure this isn’t it. Generally cognition is a skill that must be exercised continuously. That is the highest determining factor. This conclusion seems unscientific it also doesn’t seem vetted.

    I am the second oldest of nine siblings, all born in 10 1/2 years with no twins. My mother was a RN. She had 5 kids before she quit working to devote her time to us. Dad was a highly accomplished business executive at an industry leading lighting manufacturer. Every child was highly successful in their chosen field. We had good genes and a great upbringing. And, yes, we were Catholic.

    Northern European families with 4+ kids most likely belong to groups with a non-European ethnicity whereas people from groups with indigenous north-European ethnicities usually have between 1-3 kids.
    So I believe it’s rather genetics than the number of kids that effect iq and income.
    This should be easy to prove by comparing outliers, ie indigenous European families with many kids vs non-European fabulous with few or no kids.
