Political Science could be classified as both a humanity and a social science.

Explanation:

Humanity is a vast knowledge discipline that encompasses subjects like history, human geography, literature, politics, law, religion, philosophy, art, etc. On the other hand, Social Science is a multifaceted discipline of knowledge that hosts subjects like political science, economics, human geography, linguistics, anthropology, musicology, archaeology, psychology, social history, management science, etc. Political science can thus be referred to as both, a humanity and a social science subject because it enumerates the subject matter of both the disciplines.
