Sociology is a subject in which no one starts from Zero, as everyone already knows about society. However, other subjects are taught at school, at home or elsewhere.
Being an integral part of the process of growing up, knowledge about society seems to be got naturally or automatically. In case of other subjects, no child is expected to already know something.
It means we know a lot about the society in which we live and interact. As far as other subjects are concerned, prior knowledge is almost negligible.
However, this prior knowledge or familiarity with society is both an advantage and disadvantage for sociology.
In the absence of prior knowledge there is no question of advantage or disadvantage in case of other subjects.
