There is no science of people, psychology, psychiatry are not sciences.
Psychology, psychiatry, anthropology, sociology, political sciences, economics, and plenty more, which all would fall under broad classification of Social Sciences.
Social Sciences related to studies of human behaviour, human cultures, and human social activities.
Social Sciences differed from Natural Sciences.
Natural Sciences include all sciences concerning nature, and can be broken down into the following sciences:
- Physical Sciences
- Life Sciences
Obviously, life sciences include various fields in biology, like microbiology, molecular biology, human biology, zoology, botany, evolutionary biology, biophysics, biochemistry, related fields, especially those concerning studies of medicine, illnesses and diseases, etc.
Physical Sciences, on the other hand, include physics, chemistry, Earth science and astronomy.
Physics and chemistry have many applications, especially in engineering and technology, eg computers and network technologies, which in turn, have many applications. The knowledge of physics and chemistry are required in other sciences, including astronomy and Earth science.
While both natural sciences and social sciences, natural sciences only concern with biological aspects of humans, such the human anatomy and physiology, DNA, their physical health, and so on.
While social sciences concern with people’s emotions, behaviors, what they think about, how they live culturally or in societies, hence social sciences deal with the social aspects of humans.
People who studied natural sciences, like physicists, tend to think social sciences, particularly psychology, as “soft science”.
