Which field of study teaches deepening one's understanding of other cultures and viewpoints?

Politics primarily focuses on the systems of governance, political behavior, and the theoretical and practical aspects of political institutions. While it may touch on cultural issues, its primary aim is not to deepen understanding of cultures but rather to analyze power dynamics, policies, and governance structures.

Geography studies the physical features of the Earth and human interactions with the environment. Although it can include cultural geography, its main focus is on spatial relationships and environmental processes rather than a comprehensive exploration of diverse cultural viewpoints and experiences.

Psychology is the study of the mind and behavior, focusing on individual and group behavior, mental processes, and emotional responses. While it may consider cultural factors in understanding behavior, its primary objective is not to explore cultural diversity in depth, as the humanities do.
