New Research Establishes That Intelligence Is Inherited from the Mother

Anyway, I'm extremely suspicious of this result. In particular: > However, several studies revealed that children are more likely to inherit intelligence from the mother, because intelligence genes are located on chromosome X. I still don't understand how this explanation makes sense. (Assuming it's true.) If a woman has a "smart" chromosome X and a "stupid" chromosome X, then the sons have a 50% chance of inheriting each one. Do very smart women have two "smart" chromosomes X? So all the sons get an "smart" copy. Daughter are more difficult to analyze, because the chromosome X from the father make the comparison more complicated. But a father with a "smart" chromosome X will give all the daughters a "smart" chromosome X. (Probably the classification is not so simple, and there are many variations, not only "smart" vs "stupid", but let's keep it simple for the sake of the discussion.) So, in the minimal chance that this is true, I'd expect that the result have a strong correlation with the gender of the children. In particular, the intelligence of the daughters must be more strongly correlated to the intelligence of the father than the intelligence of the mother. (Assuming it's true.)

  Exactly. I also read this "study" report and saw this "researchers hypothesized..." Uh huh. And study on RATS? Rats have instinct. You know, I guess they aren't teaching history in school anymore, because a "study" just like this was attempted around 70 years ago by a man named Mengele. The study was quickly and clearly trashed, and not out of bias either, but because it was garbage. Intelligence, characteristics are not "in our DNA" as I heard a dumb psychologist actually say out loud on PBS this morning. They are learned. I also heard the Leader of the Free World, President Obama state this very phrase a few months ago on TV too: "it's in our DNA" what was in our DNA he stated? Racism! This nonsense has gone too far.
