A methodical form of science denial that is customarily used in State Pseudoscience in order to suppress undesired evidence or competing theories.
It works in 3 steps, all of which are logical fallacies:
1) Demanding conclusive evidence before any actual investigation can take place ("Quick science fallacy").
2) Treat the inevitable lack of evidence as if it was evidence of the opposite case ("Argument from ignorance").
3) Use this alleged "debunking" as an excuse to discourage any further investigation about the subject ("Science-based science-denial").
These last 2 steps in particular are reciprocally self-supporting: the more research is discouraged, the less evidence can be obtained, which is then used to discourage research even more, leading to a self-sustaining cycle of science denial that ensures the targeted subject will always be relegated into the realm of "pseudoscience" when, in fact, the real pseudoscience is the very process employed to force such a conclusion.
The circular logic of institutional science-denial.
