flaw in the research
There was no measurement of effort. I have excelled at things with little effort. Others have excelled at the same things which some, much or great effort. The scores the research looked at could not distinguish those who excelled through effort from the coasters who aced the exams. The one who excelled with little effort are obviously naturally talented in the field.
This fact applies in fields well beyond CS. I would have to say there are gifted people in any field. The opposite also applies. There are those that despite their best and strenuous effort cannot do something.
Biting the hand that feeds IT
