There isn't a single scientist who studies *all* aspects of society and interpersonal relationships. However, the field of sociology encompasses this broad area of study.

Here's why:

* Sociology is the study of human society and its structures, including:

* Social groups and institutions

* Social interactions

* Social change

* Culture

* Power dynamics

* Inequality

* Social problems

Sociologists use various methods to study society, including:

* Surveys

* Interviews

* Experiments

* Observations

* Statistical analysis

They often specialize in specific areas of sociology, such as:

* Social psychology (focuses on how individuals think, feel, and behave in social contexts)

* Family sociology (studies family structures and dynamics)

* Criminology (examines crime and its causes)

* Political sociology (analyzes the relationship between power, politics, and society)

* Economic sociology (explores the social dimensions of economic activity)

So, while there's no single scientist for all aspects of society, sociologists are the closest to studying this vast and complex field.
