These people are outliers. The problem with outliers is that they're so far out of the normal range that it's often difficult/impossible to use outliers' experiences to answer "what causes deviations within the normal range?" Were they gifted from birth? Did they have unique developmental opportunities? Did a radioactive spider bite them just so? We can analyze their lives and experiences, but we often place far too much stock in the facts of that analysis without properly assessing those facts' significance. Using Mozart & co. as [counter]examples in a discussion about innate potential/intelligence/development is about as useful as using lottery winners to derive recommended savings levels for the general population, or using lightning strike victims to derive recommendations for public safety.
