judge verdicts (4)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states that Kraepelin demonstrated 'increase in the force of muscular contractions' 'by Kraepelin for tea' in 1892 using the dynamometer method.
- qualifier_fidelity 0.50 fail — The viewpoint qualifier is incorrect. The passage attributes this finding to a named source (Kraepelin), so the claim should use 'Kraepelin' as the viewpoint, not 'author'. The quote is accurate but incomplete for supporting the full claim context. The time, stance, sentiment, and context qualifiers are faithful to the passage.
- groundedness 1.00 pass — The claim is directly stated in the passage. The quoted sentence explicitly states that Kraepelin demonstrated in 1892 that tea increases the force of muscular contractions, using the dynamometer as a measure.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly attributes the finding to Kraepelin as named in the passage. The stance 'asserts' appropriately reflects the passage's framing of this as a demonstration/finding. The sentiment is neutral, matching the objective presentation in the passage. The time qualifier correctly identifies 1892 as when this was demonstrated, with valid_from set to 1892 and valid_to as null (appropriate since the passage gives no end date). The context is empty as the passage provides no specific contextual restriction. The quote is verbatim from the passage and directly supports the claim about tea increasing muscular contraction force.
