I think that major is not as important as where
your interest lies. I am majoring in Management
Information Systems and was formerly majoring in Electrical
Engineering, but my best quizbowl subjects are history and
culture.
People don't always major in the QB
subject they are best in. I personally don't major in
history because I like the stories and cultural aspects
of it not the analysis of the social forces that
caused so-and-so to attack someone else for a sheep.
