Of course, that is what I said. We were all instinctually/emotionally based creatures at first, like most animals are still nowadays. For some reason (and this is a very interesting topic, at least to me), we managed to evolved into creatures with logic and bigger brains than other creatures AND in our own kind, for other reasons and some I mentioned up above, the males managed to become even more evolved than the females on the logic thinking.
It's because of the XY chromosome on men. Women have XX. Now they can carry two traits. Whichever trait is more dominant is whichever one that shows. Say for example, a woman has a trait for blue eyes and brown eyes. For whatever reason, brown eyes are the dominant trait so they will have brown eyes instead of blue eyes. Men on the other hand, only have one single X chromosome, which means that we can only carry one single trait. Whether or not that trait is dominant or recessive is negligible because it is the only trait we have, since again, we can only carry one trait. If a man has the blue eye trait, he will have blue eyes. If it's the brown eye trait, he will have brown eyes. He cannot have both traits at the same time. Women however can.
Well the same goes for logic. Men developed logic better because we can only carry one trait saying that we are logical. And as we all know, humans got to the top of the food chain because we are smarter and more logical than other creatures, which means that the men who had the logic trait were more likely to survive than men with the purely emotional trait.
Also, this is why the greatest feats in the world have been accomplished by men. Those great men just had the genetic predisposition to it that women likely would not have been able to have. Also, if you look at the average intelligence levels between men and women, you'll find that we both have the same average. But there tends to be more men in the smarter and dumber category as well, about a 10%-20% greater range/variance than women. It's because of the XY trait. Men are more likely to be smarter than the average and dumber than the average as well.
there was a lot of instinctual decision making going on. that is when we were using our intuition to it's optimum level. now a days,as humans, we have lost a lot of that ability.
It's still there. We just don't use it. People living in third world countries are able to use it better. It's because in places like the US, they put crap like fluorine in the water which stops the use of our pineal gland. They use the excuse that it stops tooth decay, but in reality its because one of the traits of our pineal gland is that it helps us think more for ourselves.
