Ideological belief constraint depends on stored knowledge, not identity labels alone.

Evidence

This case illustrates well what we mean by constraint between idea-elements and how such constraint depends upon a store of relevant information. For this man, “Socialists,” “the working man,” “non-Socialists” and “the rich” with their appropriate valences formed a tightly constrained belief system. But, for lack of information, the belief system more or less began and ended there. — John T. Jost and Jim Sidanius, Political Psychology, 1892
