I think epigenetics plays a large part in what we inherit from our parents. But also nutrition and environment play a large part regarding our intellectual abilities. If we don't get enough Iodine our intellectual and emotional intelligence is hurt along with the bodies systems. They are all tied together.
We have class system in the West...we can see this forming on Steemit. Once the system becomes top heavy the whole thing falls into itself...it's about time for systems to fall, they are all very corrupt.
Many systems in the past avoided the top-heavy structure by decentralizes the power structure...I think we should develop a vaccine to prevent psychopathic fetuses from developing...oh, that's not very Buddhist of me...hahaha (Bad Joke)
