The Bottom Line
There is hardly any new research on the genetics of intelligence or new study published that claims kids inherit intelligence from their mothers. The virality of splashy internet/social media claims “We Inherit Our Intelligence From Our Mothers” or “Kids Get Their Intelligence From Mom” and similar ones grows despite inaccuracies and backup from the latest research. Those catchy and attention-grabbing headlines are the culprit!
These headlines are highly liked, commented on, and shared by – people who think they are geniuses and have mothers to be grateful for and mothers who think their children are geniuses, and some feminists who would love to shout out loud that mothers bring smarts to this world. Such attention-grabbing headlines can help one win a ready-made audience.
