Why are Social Sciences subjective? It creates lot of confusion. Isn't it?

I'll just say social sciences aim at helping us understand human relationship with its environment. It deals with different human experiences with and in its environment. These experiences are experiments. And every human has various skills at understanding it's the environment; therefore, social sciences talk about these experiences. They are the only way we can understand the environment around us. 

Social Sciences subjects have emerged to facilitate Social Animals - Human beings. Such social beings have their perspective that cannot be tested or experimented in a testing lab, that natural sciences have. In Social Sciences, society is a lab, and behaviour of people determined by their social, economic and political outlook.

As people approach a social problem with their (self and motivated) sense of knowledge and understanding, we do not have one best answer in Social Sciences. Your solution can be critically better than others; however, it can never be the best answer.

Therefore Social Sciences are called applied sciences that apply scientific tools and perform research to derive feasible alternatives to existing and emerging challenges in human society.

So Social Sciences are subjective.

Social sciences attempt at an interpretative understanding of what all is social through scientific concepts and techniques. Although its experimental nature claims absolute objectivity but the human interpretation involved in making sense of the social world mainly includes a subjective analysis. Also, the agents of description already have a preconceived notion of what they intend to study, i.e. society. Thus a contradictory position to start with.

The biggest reason for being subjective to social science is that students can develop their thinking so that they can have an understanding of social problem and development of a creative mind in the school itself so that if they go for higher education, then basic understanding Let there be developed.
