Members of extreme political groups are usually perceived as more homogeneous than moderates. We investigated whether members of the general public who share the same political ideology would exhibit different levels of heterogeneity in terms of human values across 20 European countries and Israel. We directly compared the variability across moderate-, left-, and right-wing groups. Our findings suggest that the values of more extreme (left-wing or right-wing) supporters are usually more heterogeneous than those with more moderate views. We replicated this finding for politics-related variables such as attitudes toward immigrants and trust in (inter)national institutions. We also found that country-level variables (income, religiosity, and parasite stress level) did not moderate the pattern of value variability. Overall, our results suggest that endorsing the same political ideology is not necessarily associated with sharing the same values, especially in the case of common citizens holding extreme political attitudes.
