Argument from Position to Know

Also Known As: argument from insider knowledge argument from firsthand knowledge positional authority argument
Argumentation Scheme ID: argument_from_position_to_know

Definition

The argument from position to know asserts that a person's claim should be accepted because they are in a unique position to have direct knowledge of the relevant facts. Unlike general expert opinion, this scheme relies on situational access to information rather than formal credentials. A witness to an event, an insider within an organization, or someone with firsthand experience has epistemic privilege regarding the facts they observed.

Examples

The factory floor supervisor says the equipment failure was caused by a worn bearing, not operator error. She works with these machines daily and was present when the failure occurred, so her account should carry significant weight in the incident investigation.

A veteran nurse tells a hospital administrator that the new patient intake software is creating dangerous delays in emergency triage. 'I've been working this ER floor for 15 years and I'm the one watching patients wait,' she says. Her direct, daily experience gives her credible grounds to assess the software's real-world impact.

A longtime resident tells city planners that the proposed new bus route won't work because the road floods every winter and becomes impassable. 'I've lived on that street for 22 years — I know what happens every February.' Her firsthand, repeated experience gives her knowledge that the planners' maps and models may not capture.

Verification Steps
Verification Steps
Binary yes/no questions that an AI must answer to detect a reasoning pattern in a text.
Each of the 452 aspects has verification steps — simple yes/no questions designed to systematically detect whether a pattern appears in a text. For ad hominem: "Does the argument attack a person rather than their claim?" For false dichotomy: "Are only two options presented when more exist?" This ensures consistent, reproducible analysis.

Binary (yes/no) questions an LLM must answer to identify this aspect:

  1. 1

    Does the arguer cite a source who claims to have direct access to relevant information?

    Type: binary
  2. 2

    Is the source's position to know (proximity, observation, access) actually established?

    Type: binary
  3. 3

    Could the source have reason to misrepresent what they know?

    Type: binary
  4. 4

    Is the claim within the scope of what the source's position actually grants them access to?

    Type: binary
