Biology was always limiting. I don't understand why it is so hard to accept there are mental limitations, when it is clear that there are physical limitations. I will never play NBA or beat sprinter on athletic track.,(reply>), @Drozdovblog I did not try to contradict, but give an answer to your question. I think that nobody has much of an issue with statements such as: some individuals are better at chess, math, languages, writing, art or whatever single mental task. It only becomes controversial when making generalizing broad claims about mental capability and singling out root causes for those. Even going so far as generalizing those over entire continents and supposedly biological races. Even things as individual height are not that clearly genetically determined as most people think. Nurture plays a big role here too. Biology is not deterministic, but highly flexible. Think of your genes as a huge Box of Legos. You can build all kinds of things with that.,(reply>), @aexesia Yes, I don't dispute this. That is not contradicting what I wrote.,(reply>), Because we are talking about something much broader than a single task. There is no one physique that is best for everything physical, just as there is not one intelligence aspect that is best for everything.
