A theory may only ever be proven wrong. The potential for it being proven wrong always remains.
An Anti-theory may only ever be proven correct. It is based upon evidence not yet discovered, known, or found. It is perpetually waiting for the “final evidence”, regardless of whether it will ever be found or not. It is based upon a yet undiscovered evidence that will actually prove itself. This is simply a poor and self-serving methodology.
Waiting, as a perennial solution to a given problem, becomes an Anti-theory.
The Anti-theory can never be proven wrong, while the Theory can only ever be proven wrong.
