Each codebook was searched for a pubic-hair or Tanner variable, and each XPT file's column names were listed. The codebooks describe anti-Müllerian hormone and inhibin B. They do not contain a pubic-hair stage or an age at spermarche. Without that variable the pre-registered onset age cannot be computed, so the verdict is inconclusive with reason data-unavailable. https://w3id.org/delphi/resource/assessment/aristotle-ha07-01--claim-test http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/aristotle-ha07-01--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: null years at pubic-hair onset (n = 0). Interpretation: The claim is about human males: seed production and pubic hair begin together at about fourteen, which Aristotle also calls twice seven years. 'About fourteen' is the three-year window from 13 through 15. The measurable pubic-hair marker is Tanner stage 2. Semen is used only if the same examination files record it. This does not test ancient Greek populations; it tests the age the claim states against a modern public examination. https://w3id.org/delphi/resource/assessment/aristotle-ha07-01--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ha07-01: inconclusive, confidence 0.9 https://w3id.org/delphi/resource/assessment/aristotle-ha07-01--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ha07-01/result.json https://w3id.org/delphi/resource/assessment/aristotle-ha07-01--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-ha07-01--claim-test https://w3id.org/delphi/ontology/admissibleDatasets NHANES physician sexual-maturity examinations of boys with a Tanner pubic-hair stage and age, public microdata, cycles that include the exam.
