argument_from_silence
The argument from silence draws a conclusion based on the absence of statements, evidence, or documentation. It reasons that because something was not mentioned, recorded, or addressed, it did not happen or does not exist. While silence can sometimes be informative (especially when someone had reason and opportunity to speak), it is generally a weak basis for positive claims.
"The ancient Romans never wrote about kangaroos, so they clearly never visited Australia." (While the conclusion may be correct, the absence of written records is weak evidence on its own.)
A conspiracy theorist insists: 'The government has never officially denied that they have alien technology at Area 51, which proves they're hiding something.' (The absence of a specific denial is treated as confirmation of the claim.)
A job applicant is rejected and tells a friend: 'The interviewer never said I was underqualified, so the real reason must be discrimination.' (The lack of a stated reason is used to infer a specific, unverified explanation.)
NOT Stated(Authority, P) -> NOT P
Binary (yes/no) questions an LLM must answer to identify this aspect:
Is the absence of a statement or evidence being treated as proof?
Type: binaryCould there be reasons for the silence other than the claim being false?
Type: binaryIs the source expected to have addressed this topic if it were relevant?

People expect important things to leave traces. The absence of expected evidence feels like evidence of absence, especially when we assume records are comprehensive and reliable.
Point out that absence of evidence is not evidence of absence. Consider whether the silence could have other explanations: records may be lost, the topic may have been considered unimportant, or the speaker may have had reasons not to mention it.
Common in historical argumentation, legal cases based on lack of documentation, conspiracy theories that interpret government silence as proof of cover-ups, and academic debates about ancient texts.
