The term "conspiracy theory" is itself the object of a type of conspiracy theory, which argues that those using the term are manipulating their audience to disregard the topic under discussion, either in a deliberate attempt to conceal the truth, or as dupes of more deliberate conspirators.
Perhaps the most contentious aspect of a conspiracy theory is the problem of settling a particular theory's truth to the satisfaction of both its proponents and its opponents. Particular accusations of conspiracy vary widely in their plausibility, but some common standards for assessing their likely truth value may be applied in each case:
- Occam's razor - is the alternative story more, or less, probable than the mainstream story?
- Methodology - are the "proofs" offered for the argument well constructed, i.e., using sound methodology? Is there any clear standard to determine what evidence would prove or disprove the theory?
- Whistleblowers - how many people—and what kind—have to be loyal conspirators?
