I believe that foremost it's pattern recognition and abstraction that is tested in IQ tests. No matter in what field people who excel at pattern recognition or abstraction, or both are considered very talented. Yet, other peers in the same field might be competent enough for that field, but they lack talent, the ability to go beyond their general competency in that field. That means, you don't have to have genius level IQ to do well in science, formal training and determination are enough in most cases. High IQ in contrast does not guarantee that the person knows how to put their talents to use, without formal training that is. A bearer of a PhD diploma might still be dumb as a rock, but thanks to formal training, it doesn't seems as obvious. On the other hand, there are people who might be considered low IQ, because they were "too dumb" even for high school, but actually have genius level IQ. It wasn't obvious that they were intelligent, because their abilities weren't seen as such, as they couldn't solve the easiest stuff.
