Claim-by-Claim Results
claim_id: example_claim_1
- Subject: well-being in biophilic offices

- Final phrasing: "Self-reported well-being increase"
- Source: Human Spaces / Interface (2015)

claim_id: example_claim_2
- Subject: cortisol response in natural environments
- Classification: QUALITATIVE-ONLY
- Final value: "Significant reduction" (no percentage)
- Final phrasing: "Nature exposure reduces cortisol (Antonelli et al., 2019 meta-analysis)"
- Source: Antonelli, Barbieri & Donelli (2019). International Journal of Biometeorology.
- URL: https://pubmed.ncbi.nlm.nih.gov/31001682/
- Quoted passage: "Forest bathing can significantly influence cortisol levels on a short term in such a way as to reduce stress."
- Why not quantified: Meta-analysis reports significant effect sizes but no single clean percentage appropriate for a hero number.
claim_id: example_claim_3
- Subject: hypothetical symmetry-bias claim for the comparison side
- Classification: REJECTED
- Reason: No peer-reviewed source locates this specific number. Appears only in marketing pages with no traceable primary paper.
- Action: Remove from layout, or replace with a QUALITATIVE-ONLY descriptor drawn from a related verified study.
Fabrication Risks Detected
List any patterns that suggested numbers were being invented, e.g.:
- Symmetry bias. The right-hand side of the versus comparison has only 2 VERIFIED claims to the left's 5. Planned layout will be asymmetric; no filler statistics will be invented.
- Meta-source attribution. User-suggested citation to Browning et al. (2014) demoted — it is a review, not the primary source for any specific percentage.
- Geographic misattribution. User suggested "Finnish studies" for cortisol research; replaced with correctly attributed Japanese Shinrin-yoku literature.
