Theories of political behavior, as an aspect of political science, attempt to quantify and explain the influences that define a person's political views, ideology, and levels of political participation. Theorists who have had an influence on this field include Karl Deutsch and Theodor Adorno. There are three main sources of influence that shapes political orientation which create long-term effects. Generally, the primary influence originates from family. As stated previously, children will often adopt their parents' ideological values. Some theorists have argued that family tends to be the strongest, most influential force which exists over the lifetime; one essay has credited the majority of the student activism of the 1930s to the influence of parents.
