In short: no. I have seen tens of examples where people of incredible logical/analytical heritage sink to the bottom of the barrel, as well as those that rise to the top from no discernible "good" set of genes. There is more, I believe, than being born in making a person understand and function on a logical level. It requires a whole set of correct external stimuli, as well as a certain drive. For me, I can clearly define two key points in my life: one that got me started in the right logical way, and one that directed me into computers specifically. As for the drive, it's also very much a function of environment, because I have seen my own motivation and desire tide and ebb depending on various external inputs. In conclusion, I would say that there is potential in a majority of us to achieve amazing things, yet this potential requires specific grooming to blossom.
