Confidently asserting that a theory or hypothesis is true or false even though the theory or hypothesis cannot possibly be contradicted by an observation or the outcome of any physical experiment, usually without strong evidence or good reasons. Making unfalsifiable claims is a way to leave the realm of rational discourse, since unfalsifiable claims are often faith-based, and not founded on evidence and reason.
Examples:
- I have tiny, invisible unicorns living in my anus. Unfortunately, these cannot be detected by any kind of scientific equipment.
Synonyms: untestability
