In addition, the five disciplines next least likely to be politically correct were Biology(2%), Computer Science (3%), Accounting (4%), Marketing (4.5%), and Economics (4.7%). All in all, these numbers aren't surprising: I can't imagine what a politically correct approach tom teaching finance would entail (maybe an NPV of a project that differs based on the race, gender, or class of the project manager?).
Humanities and social science fields tend to have higher politically correct rankings, while professional and science disciplines do not. The table that follows is in order of political correctness. Psychology is the only field where a majority of professors are politically correct. Four fields — finance, management information, mechanical engineering and electrical engineering — had no one who was politically correct (emphasis mine).
