There are many threads here discussing the influence of genetic factors but this is not what the article is about. Genetic factors are not mentioned in the article. One of the last paragraphs states other possible factors explicitly:

> Her next step is to find out what factors contribute to being an expert on an instrument, playing field, in the classroom or at work. She hopes to investigate such factors as basic abilities, age when starting to learn the skill, confidence, positive or negative feedback, self-motivation and the ability to take risks.

I think the whole nature vs nurture discussion in relation to intellectual aptitude is shaped to much by peoples own biases which leads them to ignore the overwhelming evidence for the importance of nurture/culture/eduction/...

Maybe it's easier to believe some people are born smart.
