This chapter analyzes the reasons of ideological self-placement on the left-right scale of MPs and citizens. It assumes that individuals’ ideology responds to three major factors: values, social structure and party identification. Using descriptive statistics as well as OLS regression models, the research shows that social structure explains a large amount of the left-right variance in both MPs and citizens, mainly due to the association of religious identity with ideology, far above the weight of egalitarian or libertarian values. It also confirms that the partisan factor is more important for citizens than for MPs, which is consistent with the superior political knowledge of the latter.
