Another excellent way to find an argument is to identify a puzzling phenomenon – something that goes against most people’s expectations (or those of a major theory in political science). If you can account for the phenomenon (your explanation will be your argument) you will have achieved something significant. The phenomenon may be puzzling in the light of a particular theory or set of expectations. For instance, why did the EU member states not react to the onset of globalization with a protectionist response? Here looking for an alternative explanation (an opposing argument) is not always necessary.
