Abstract
Psychology aims to understand human cognition and behavior, which necessitates making use of sociological-political theories. Social Dominance Theory (SDT) is one of the psychological theories that try to explain the individual-society relationship from a broad perspective. Yet, this theory has its shortcomings too. In an attempt to contribute to a well-grounded theory for psychological research, the paper at hand will discuss the shortcomings of SDT. The main discussion concerns following appropriate logic while making assumptions, and proper interpretation of historical and evolutionary data: it is suggested that no single theory, including SDT, is capable of embracing such a wide subject and SDT can be utilized only in some aspects of this subject.
