I find this kind of research and political science to be ill-equipped for explaining how people and society work. Fiction like Nabokov's Bend Sinister is able to get much closer to the truth of totalitarianism because it isn't shackled by having to present a thin veneer of data and science, and is more clearly influenced by the author's experiences and POV. Social Science often acts as a cover to smuggle these personal experiences into academia and the news.

It's absurd to act like a dataset of Argentinian military promotions is rigorous or valid enough to make any kind of conclusion about how authoritarianism works. This type of "science" is no help in how we all live and work together and our individual experiences are all we really have to help us navigate society.
