Hard to define, for those looking are looking for sideshow results. I think peak skills in narrow fields are very common, "Splinter Skills",
The larger problem is looking at IQ, a range of performance, seeking Normal performance.
All performers exceed the Normal human range, which is why there are painters, writers, musicans, and mechanics. While everyone can do these things, few are good enough to be considered talented.
For most it is gifts with costs in other areas, just no interest and not enough hours to be good at all things, and few records of multi gifted, Nobel Prize in Physics and first chair violin solos.
When one interest takes over, one human of energy directed in a narrow beam, there are results, but the landury, bathing, eating, sleeping, talking, get left out.
The history of exceptional skills is one person has them, they are a problem, but very often, their way becomes the future, as it works. They die broke, but billions are made over the next fifty years.
Not good for the person, not good to their time, but almost everything of value to the species.
It is not living in the future, but almost all people live fifty to a hundred years in the past. Those who live in the present, see what could be done, upset the larger group with the threat of change.
Most live in lag time, few in the now. The future and the species likes the few who focus on now.
