Every number links to where it was published. Low-confidence rows are muted and need per-cell verification.
Combines paper-derived mechanisms from 14 scientific fields with real-world datasets containing 17.98 million records. It preserves observational complexity while providing specified underlying mechanisms for hypothesis generation.
Assesses open-form hypotheses by evaluating their consequences under withheld conditions using ground truth outcomes. Experiments reveal a substantial gap between generated hypotheses and underlying mechanisms.
