The presented research is part of the pursuit of psychological determinants and factors differentiating between voting behaviors and ideological preferences of Polish voters. Many empirical studies prove the existence of significant relations between the values preferred by a person and the person’s behaviors, which also has its robust evidence in the area of studies on electoral behaviors. The aim of the article is to analyze the system of higher-order values (conceptualized by Shalom Schwartz) of the 2015 parliamentary election electorates and individuals with different ideological self-identifications. The obtained results point to several interesting issues, e.g. they show the weakest preference for strength ening oneself, common for all the electorates, and the most contrasting system of values represented by the voters of the Kukiz`15 group.
