Origin As a social science, contemporary political science started to take shape in the latter half of the 19th century and began to separate itself from political
philosophy and history. Into the late 19th century, it was still uncommon for political science to be considered a distinct field from history. political scientists are also marked by a great concern for "
modernity" and the contemporary
nation state, along with the study of classical thought, and as such share more terminology with
sociologists (e.g.,
structure and agency). The advent of political science as a university discipline was marked by the creation of university departments and chairs with the title of political science arising in the late 19th century. The designation "political scientist" is commonly used to denote someone with a doctorate or master's degree in the field. Integrating political studies of the past into a unified discipline is ongoing, and the history of political science has provided a rich field for the growth of both
normative and
positive political science, with each part of the discipline sharing some historical predecessors. The
American Political Science Association and the
American Political Science Review were founded in 1903 and 1906, respectively, to distinguish the study of
politics from economics and other social phenomena. APSA membership rose from 204 in 1904 to 1,462 in 1915. As part of a United Nations Educational, Scientific, and Cultural Organization (UNESCO) initiative to promote political science in the late 1940s, the International Political Science Association was founded in 1949, along with national associations in France in 1949, Britain in 1950, and West Germany in 1951.
Behavioral revolution and new institutionalism In the 1950s and 1960s, a
behavioral revolution stressing the systematic, rigorously scientific study of individual and group behavior swept the discipline. A focus on studying political behavior, rather than institutions or interpretation of legal texts, characterized early behavioral political science, including work by
Robert Dahl,
Philip Converse, and in the collaboration between sociologist
Paul Lazarsfeld and public opinion scholar
Bernard Berelson. The late 1960s and early 1970s witnessed a takeoff in the use of deductive,
game-theoretic formal modelling techniques aimed at generating a more analytical corpus of knowledge in the discipline. This period saw a surge of research that borrowed theory and methods from economics to study political institutions, such as the United States Congress, as well as political behavior, such as voting.
William H. Riker and his colleagues and students at the
University of Rochester were the main proponents of this shift. Despite considerable research progress in the discipline based on all types of scholarship discussed above, scholars have noted that progress toward systematic theory has been modest and uneven.
21st century In 2000, the
Perestroika Movement in political science was introduced as a reaction against what its supporters called the "mathematicization" of political science. Those who identified with the movement argued for a plurality of methodologies and approaches in political science and for more relevance of the discipline to those outside of it. Some
evolutionary psychology theories argue that humans have evolved a highly developed set of psychological mechanisms for dealing with politics. However, these mechanisms evolved to deal with the small-group politics that characterized the ancestral environment, not the much larger political structures of today's world. This is argued to explain many important features and systematic
cognitive biases in current politics. ==Overview==
