This paper sheds light on the reasons that explain the dissatisfactions because of the behavioralist dominance within American political science academia. I show how and why the flaws and failures of the behavioralist analysis have created more room for the emergence of alternative approaches or new ideological movements in the study of politics. These competing paradigms or approaches are mainly post-behavioralism, postmodernism, and the Perestroika movement. Moreover, under a comparative framework, I explain why behavioralism is still the dominant paradigm within American political science academia despite all the efforts of the alternative paradigms to displace it
