Aptitude is in general going to be either uncorrelated or positively correlated across different areas, but time invested is going to be negatively correlated. Hence the stereotype of nerds with poor social skills: building social skills takes time and effort, and time and effort spent on building those skills is time and effort not spent on, eg, improving your programming ability.

Of course, people who have off the charts aptitude will be in the top percentiles across the board. But you're not going to find too many organizations staffed entirely by those people.
