>>It implies that a person of normal natural abilities has a shot at becoming world-class
The key lies in the definition of normal. Does it mean no less than 1 standard deviation below average? Does it mean above average? Above 1 standard deviation and less than 2? See, people in all those ranges are normal, and just by reducing a little the scope of "normal" a lot of people are filtered out.
My conjecture is that at least above average innate abilities are required, which by definition leaves out half the population.
