I don't like the term "political science."  If anything, politicking is an art form, not a scientific pursuit.  Lumping the two words together is a disgrace to the world of actual science. 

I feel somewhat the same about "food science."  I know there's actual science involved in the interaction between food chemicals and human taste buds, but in practice I just see chefs in a kitchen, which is inherently artistic.  Food scientists can take that as a compliment if they so choose.
