THE TERM ‘CONSPIRACY THEORY’
This phrase is among the tireless workhorses of establishment discourse. Without it, disinformation would be much harder than it is. “Conspiracy theory” is a trigger phrase, saturated with intellectual contempt and deeply anti-intellectual resentment. It makes little sense on its own, and while it’s a priceless tool of propaganda, it is worse than useless as an explanatory category.

If we say, 9-11 was orchestrated by the bin Laden organization, the Pakistani intelligence agency, and elements of the neoconservative group that seized power in 2000, that’s an hypothesis, derived logically from a set of documented facts that constitute evidence. It isn’t a theory. It can become part of a theory if it’s joined with other hypotheses into a coherent descriptive pattern that can help to predict future events in general terms.
For instance, the amply demonstrated hypothesis that the 35th President of the United States was murdered by a consortium of interests including the CIA, Cuban exiles, organized crime, and the military. 11-22 and 9-11 are examples of premeditated murder by more than one person – in law, they are cases of conspiracy to commit murder (and fraud, and perjury, and treason). Taken together, they imply a theory whose greatest expression is the work of Peter Dale Scott, who coined the term deep politics: “the constant, everyday interaction between the constitutionally elected government and forces of violence, forces of crime, which appear to be the enemies of that government.”<7> Deep politics is a robust theory, a powerful explanatory account of demonstrable phenomena; it applies to myriad cases and offers a unified understanding of their causes and meanings. Like Goethe’s conceptual account of color, and like Newton’s rival account which refuted it, Scott’s deep-political theory applies uniformly to the domain it describes.
Conspiracy, on the other hand, is a hypothesis about a particular case at hand. The only rigorous meaning that the phrase “conspiracy theory” can have would be that political crimes involving more than one actor are usually exceptional episodes unrelated to one another – rather than the ongoing, systemic and unacknowledged relationships between authorities and the criminals they are paid to hinder and to punish.
