Ideology refers to a set of beliefs or values that shape an individual or group's worldview, guiding their thoughts, actions, and behavior. It can encompass a wide range of beliefs, from political, religious, or social ideologies to economic or cultural beliefs. Ideologies can be both explicit and implicit, and often serve as a framework for understanding the world and making decisions. Research in ideology seeks to understand how these belief systems are formed, maintained, and change over time, as well as how they influence behavior and social structures. It also examines the role of ideology in shaping public opinion, political movements, and societal norms.
