Geniuses are made

I've been fascinated with the topic of 'Genius'. Ever since I can remember I've read everything I could lay my hands on regarding the development of people with special abilities. Especially mental abilities. One that has stood out to me was a memoir of the parents of a genius level child. I've read this many years ago but I can remember the general outline of this story. In the Lifehacker article, the contention is made that it's the environment in which such people are raised that creates their 'genius'. If my memory serves me, and it usually does, the child in this particular memoir came from an average house. The father worked in a technical vocation and the mother devoted the same time to this child as she did to her others. Yet, the 'genius' child, expressed himself faster and far more eloquently than his siblings. He had the same upbringing and environment as his brothers and sisters, yet excelled. He read copiously at an earlier age than them and understood complex material with greater ease than them. He was advanced through school far more rapidly and eventually graduated with a doctorate in science around age nineteen or twenty.
I would venture to contend that, yes genius is made. But, you cannot make an omelet from anything but eggs.You need the basic ingredients in your brain to be able to make the connections between the abstracts concepts that you are bombarded with and the language with which you have to express yourself. There is no way anyone can appreciate your genius, if you don't have the language skills and innate ability to communicate your thoughts to the rest of the population. Just take a simple discussions concerning the oxymoron 'Reality TV'.
It's NOT real. Never can be. Good television makes sure it cannot be real. It falls neatly in the category of 'Reality has one thing over fiction, fiction has to make sense'. To make sense of what is presented as 'Reality TV', the producers need to setup and explain what is happening in one hour or less.Thus, the reality is condensed and squeezed down to fit in this time. Participants are chosen specifically for their 'reality flaws'. They make for more dramatic TV and higher ratings.
