Thank you for the link. You wrote students, while I meant professional programmers. It's not because some people have a tougher time learning those things (whatever the reason can be) that they have no change to get them by the moment they are active professionals. This said, if I tried to apply your grouping to the people I have been interviewing last year, I would have approximately 100% of them in one category, hence my comment.
