Didn't expect Lady Gaga to be listed although it confirms one of my pet theories. It has long been my opinion that success in STEM fields correlates with general high intelligence which will affect strongly with a person's success in her field, be it maths or sculpture.
It's only anecdotal but I've noticed that people that have a good grasp of maths when young also excel in their other favorite activities, even if it's physical activities.
EDIT: more thoughts on the article
> In Europe, support for research and educational programmes for gifted children has ebbed, as the focus has moved more towards inclusion.
This is truly a pity, and it's not only about educational programmes, but the general mentality in Europe is against competitiveness, and sometimes people will even frown at you if you suggest that there truly are different intelligence levels among the population.
Meanwhile in East Europe (namely Romania, Moldova, Ukraine, Russia, probably other countries too but I don't know anything about them) competitiveness between children is crazy high in some circles and that's why a lot of the best engineers come from that area.
There was a comment here the other day on a post about interviewing saying that russian candidates were much more likely to excel at technical interviews than european candidates, and in my experience many more engineers in this area are really dedicated to their work.
