In the study, the level of university students' hierarchy-enhancing ideologies was examined in terms of gender and income variables. The research was completed with a sample of 459 people. Significant differences were found between the Social Dominance Orientation (SDO) of the participants according to gender and income variables. It was found that (in both two sub-dimensions of SDO) male participants had higher levels of group-based dominance and opposition to equality than female participants. In addition, opposition to equality levels of the participants in the study differed significantly according to their income levels. But there is no significant difference in group-based dominance levels.
