judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly states that an investigation by Harvard University's Bureau of Business Research in 1919 among 250 stores showed 'the average cost was fourteen percent,' matching the claim exactly.
- qualifier_fidelity 0.60 fail — VIEWPOINT ERROR: The claim attributes the statement to 'author', but the passage explicitly attributes it to the 'Bureau of Business Research, Harvard University' as the source of the investigation. The viewpoint should be 'Bureau of Business Research, Harvard University' not 'author'. Additionally, CONTEXT ERROR: The claim lacks necessary context that restricts this finding to the specific study population - 'among some 250 stores in small and large cities' - which is important for understanding the scope and applicability of the statistic.
- groundedness 1.00 pass — The claim is directly stated in the passage. The passage explicitly reports that an investigation by the Bureau of Business Research, Harvard University among 250 stores in 1919 showed that the average cost was fourteen percent, which matches all elements of the claim including subject, predicate, object, source, time period, and context.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly attributes the finding to the Bureau of Business Research, Harvard University. The stance is appropriately 'asserts' as the passage presents a definitive finding. The sentiment is neutral, matching the factual, data-driven tone. The time qualifiers (when: 1919, valid_from: 1919, valid_to: 1919) accurately reflect that the investigation was made in 1919. The context accurately specifies 'among some 250 stores in small and large cities,' which properly restricts the scope. The quote is verbatim from the passage and directly supports the claim about the fourteen percent average cost.
