It may be intellectually sloppy, but it can be the fastest way to get noticed.
International relations scholars like ‘isms’ for the same reason that television execs like reality TV. They have much lower production costs, as they are much less arduous and cognitively taxing than intense empirical work, which is the equivalent of scripted television. For regular workaday scholars, they are just the kind of brainless thing to sit down and read after a long, mentally tiring day. ‘Iron Chef’ trumps ‘The Wire’ any day. They might feel guilty about it, but this is what they end up talking about at the hotel bar at conferences, which is closest thing to a water cooler that international relations scholars have.
There are still outlets for non-‘ism’ work in excellent niche journals with a more narrow readership, where nuance and sophistication are still important, much like cable TV. But whatever you do, do not start blogging. That is a ticket straight to the D-List.
Love the analogy. If you are into this stuff at all, you'll want to read the whole thing.
