I think this confirms what a lot of us intrinsically felt: Some people are just better at certain things than others. Jeff Bezos came to this realization while he was in college:
"Intent on becoming a theoretical physicist and following the likes of Einstein and Hawking, he discovered that although he was one of the top 25 students in his honors physics program, he wasn't smart enough to compete with the handful of real geniuses around him. 'I looked around the room,' Bezos recalls, 'and it was clear to me that there were three people in the class who were much, much better at it than I was, and it was much, much easier for them. It was really sort of a startling insight, that there were these people whose brains were wired differently.' The pragmatic Bezos switched his major to computer science and committed himself to starting and running his own business." [1]
