The more we study chimps the more we realize that we, as their descendants, are pretty vicious as well. Education by our parents, schools and social circles play a big role, to keep in check that viciousness. How much is any ones guess!
In my opinion we are gonna solve many of the psychological problems of humans in single digit years in the near future. Dr. Daniel Amen, have stated that after examining a hundred thousand brain scans of humans, every single psychological problem people have, is observed in brain scans, as reduced electrical signals in the brain. Problems like suicidal thoughts, depression you name it. Every one of them, means the brain do not fire enough electrical signals.
The best natural substance in the world, which we produce here in Greece from the ancient times, to solve that problem, is saffron. It is on par with the best synthetic anti-depressants, and probably better. Dr. Amen eats saffron every day, and i do as well.
So there is a solution for every person on the planet to be genius 1000x or a 1.000.000x, never suffer psychological ailments, and that is to eat a lot of saffron every day. Then most of the virtues in that list, will come natural to humans.
