"The standard IR article consists of pushing a huge rock of theory up a steep hill, in order to roll it down to smash a few pebbles of fact at the bottom. That is, the modal manuscript starts by outlining the three standard theories: realism, liberalism, constructivism (sometimes subdivided into neo-realism, neo-liberalism, and so on). Articles then diverge slightly - some seek to show that these apparently different theories can really be combined to show X; others seek to show that one of the theories is right and the other two are wrong, as evidenced by an explanation of X; a few argue that none of the three quite suffices to explain X, so we need a new theory (or more frequently, a variant of one of the old ones)." J. Hochschild (2005), as cited in The Oxford Handbook of International Relations (p.110).
