As any Philosopher of Science will tell you formal theories serve as explanations to observed phenomena, an association between the explanandum – the object of phenomena to be explained; and the explanans – the framework, concept or theory to be used as an the reference point for explanation. Pioneers in philosophy of Science such as Hempel coined this logic inference to the best explanation.
Employing a Meta theory that explains a form of social reality and existence has long been the goal of Philosophers who propagate abstract thinking and rules of logic to define and set the boundaries of ontology and epistemology. In Political Philosophy one often has the espousing of an Ideology: A set of ideas that best serve to explain political and social phenomena and thus attempting a correlation between the theory used in explanation with that of the “goings on” observed. For long periods in history Philosophers and Social Scientists have debated whether Liberalism, Marxism, Anarchism, Structuralism or Methodological Individualism best serve as theoretical explanations of social reality.
In this same instance we find Ideologists today who advocate Conspiracy Theory. Like so many others in the realm of theoretical and philosophical explanation they too employ ideal frameworks that account for observed phenomena. Regardless of the aspects that encompass specific conspiracy theories, whether they are single point conspiracy theories like 911 or Meta conspiracy theories of the New World Order, they all occupy the spectrum of political ideology. This is because they advocate an explanation for observed phenomena. As where Marxism does it through the lens of capitalism and its dialectic with the human essence, Liberalism through inalienable individual property rights, conspiracy theorists do it through the lens of an esoteric operating cabal – for instance a horde of business and political agents responsible for 911 and its cover up.
