These skills apply to many analyst jobs in DC. Path to political glory: become manipulative policy / econ/ PR wonk -> get high paying / low influence job in DC -> catch someone powerful doing blow off a hooker -> get on ticket in home district -> forget you ever learned these skills -> become member of congress -> retire after one term after someone catches you doing blow off a hooker -> become Fox News regular -> book deal
From my perspective there doesn't seem to be any one field that combines all of them, but there do seem to be many permutations popping up that combine multiple fields - ie. the rise of Behavioral Economics (mostly just psych + econ). It seems like most of the cutting edge research in any given social science field that I read about is usually just a mashup of two previously divided schools of thought.
psychology, communications, economics, sociology, philosophy, history, political science, journalism, etc. can combine all of psychology, communications, economics, sociology, philosophy, history, political science, journalism, etc.
