I understand “not even wrong” to be synonymous with unfalsifiable in the sense that the statement being described as such is not a truth claim, or is otherwise not a valid formal statement or claim, such that the scientific method is not able to be deployed to consider its validity.
> In religion, a truth claim is an assertion that the belief system holds to be true; however, from the existence of an assertion that the belief system holds to be true, it does not follow that the assertion is true. For example, a truth claim in Judaism is that only one God exists. Conflicting truth claims between different religions can be a cause of religious conflict. The theory of truth claims has been advanced by John Hick.
