A Dimension Reduction Method Application to a Political Science Question: Using Exploratory Factor Analysis to Generate the Dimensionality of Political Ideology in the Arab World

Abstract

This paper utilises data dimension reduction to settle a heavily debated question concerning the dimensionality of political ideology in the Arab World. It relies on recent data available through the World Values Survey to generate a stable solution for the number of important and exciting dimensions defining ordinary citizens’ political attitude structures. The findings of the analysis suggest that in four Arab states, political ideology is multi-dimensional on the mass level. This negates the widespread assumption made about Arab politics where Islam and secularism constitute the only dimension organising voters’ attitudes and behaviours. This is important because many analyses of Middle Eastern politics start with this assumption without questioning its validity. Further, models of political ideology are to be modified when transferred to studying Middle Eastern political attitudes. The single-dimension hypothesis applicable in some Western settings is not attainable in the Arab World.
