I think CS is unique in two ways. The first one way is it has a unique pipeline. Many CS majors started off tinkering around with their computers in ways that many high school girls don't.(where as most people's first experience with math/other stem is through classroom instruction)

The second is that programmers are perceived(rightly or wrongly) to be more lacking of social skills than other equivalent professions.

i.e. the office versus silicon valley
