Political Science  

Like Sociology,political science tends to operate on a group or societal level,but its focus is narrower.

It is concerned with human behaviour as it relates to government and politics.

Among the areas of interest to political scientists is the development of political institutions,such as systems of government and political parties,and how the public
relates to these institutions through such means as voting,political-party participation,
running for office,writing letters,and participating in protest marches.
