Which study focuses on the relationships and interactions of humans within society?

The study that focuses on the relationships and interactions of humans within society is sociology. This discipline examines how individuals and groups interact, the structures of social relationships, and the patterns that emerge within societies. Sociologists analyze a wide array of social phenomena, including family dynamics, cultural norms, social institutions, and collective behaviors. The research conducted in sociology seeks to understand social order, conflict, and change through the lens of human interaction and the societal context.

Anthropology, while it also deals with aspects of human behavior, traditionally focuses more broadly on the cultural, biological, and historical aspects of humans, often looking at societies in a more holistic or comparative context rather than the specific social relationships emphasized in sociology.

Political science centers primarily on the theory and practice of politics, governance, and the impact of political systems on society, which is more focused on structures of power and governance than on interpersonal relationships.

Economics deals with the production, distribution, and consumption of goods and services, focusing on how people manage resources and make decisions related to economic activities rather than the specifically relational aspect of human interactions.

Overall, sociology distinctly emphasizes the relationships and interactions among individuals in society, making it the most fitting choice for this question.
