Given that you would have to fall into the extreme tail end of the normal distribution you ipso facto need fortunate conditions to become one to have a genius level IQ. And geniuses themselves are likely normally distributed as to their contributions to the world. So you multiply two very slim possibilities that you first have a very high IQ and that you then go on to do something noteworthy. I'm not sure that's a very helpful thing to think about though. You don't have any reasonable expectation of controlling that. I think one thing to consider is your scenario is personal choices made by the individual. If they have genius level IQ at least one of their parents has to have a significantly above average IQ and is, on the balance of probabilities, likely interested in educating their child. But let's take the hypothetical that the home environment isn't encouraging at all. When you raise kids you don't spend every waking moment with them, there is plenty of time you leave them to their own devices and they choose what they do based on what's available to them and what interests them. Kids pester their parents pretty damn hard to get what they want. Let's assume there are pretty cold and uncaring parents. Well you will probably be in daycare, so you're not at home all the time and the chance you also go to a wretched daycare is not that high, so assume you are exploring and developing your intellect there. Then you go to school and that continue s. Maybe you are too far ahead and get bored and are diagnosed with a learning disability. As you get older you gain more freedom. Perhaps you discover the library and it makes you feel wonderful that you can learn so much and you don't get such good feelings anywhere else, so you spend more and more of your time there reading and nurturing yourself. Maybe, just maybe, you nurture yourself into a genius still.
