Huh?

No. LaTeX has a strong (and growing) following in most social sciences, particularly among people doing more technical work.

Again, not quite. Some social sciences (economics, political science) are split between Word and LaTeX. Not surprisingly, the more technical the work, the more likely LaTeX will be used.

Actually, all the social sciences are great fields for people with good quantitative/analytical skills. Political science is far more technical than most people realize (and every bit as much so as economics), and sociology, psychology, anthropology (physical, not cultural), geography, etc. are all fields in which people with good skill sets will be well-positioned to get ahead. Plus (unlike contemporary economics), those fields are actually interesting...
