In studies of mass ideology, it is often found that political values are ordered two-dimensionally among the public at large. In a first economic dimension, equality is contested; in a second cultural one, individual freedom is contested. While this general rule of two-dimensionality applies to the public at large, there are large differences between educational categories. While two-dimensionality is found for the lower educated, the higher educated order their values along a single dimension and hence show more value coherence. Using a recent Dutch national survey, we show that these differences between the higher and the lower educated cannot be explained by differences in political competence. Instead, a combination of cultural and economic insecurity is responsible for the lower levels of value coherence among the lower educated.
