We continued with the behavioralist theories. These are starting to look like cold laboratory type analyses, not concerned so much with people but with data. Behavioralists want an ideological world, not necessarily a better world, as they thought culture was artificial. These are the main criticisms of behavioralism in the late 60s. As IR theorizing developed, different titles were associated with different schools of thought. Traditionalists were linked to international politics, behavioralists with international relations, and post-behavioralists with world politics.
Morganthau contributed some insight into this debate, he said at the end IR is all about psychology, when you know how things happen at the interpersonal level you can interject that knowledge to the international stage. He was concerned about the first level of analysis, what happens within the state. From actor-state-interstate.
