It is interesting to note how vastly this has changed in recent times. I'd wager that at that point, there really wasn't that much to learn about programming, it was a field in its infancy; hence, any differences between programmers were purely based on their inclination towards programming. At this point, there is so much to learn and so many different perspectives to see things from, that knowing the right things might be a huge factor in productivity. Also, its possible that when the study was conducted, programming wasn't sufficiently developed to require significant skill. Very interesting to see overall, I'd love to hear others opinions on this. Also, business insider apparently has no clue that this is a 30 year old study. No mention of that at all. ><. 30 YEARS!
