unfalsifiable
Beyond any disproof
Unfalsifiable describes a claim or theory that cannot be proven wrong because no possible evidence could contradict it.
The term is central to philosophy of science—Karl Popper argued that unfalsifiable statements, while not necessarily false, fall outside the realm of science.
The existence of an invisible dragon that leaves no trace is unfalsifiable.
Conspiracy theories often shift to become unfalsifiable when believers dismiss contradicting evidence as part of the conspiracy itself.
