JudgmentBench: Comparing Rubric and Preference Evaluation for Quality Assessment

ArXi:2605.25240v1 Announce Type: cross Two methodologies dominate current practices of benchmarking: rubric-based scoring evaluates items against predefined criteria, whereas comparative judgment elicits pairwise preferences between outputs. Although both methodologies are widely used, the choice between them is rarely justified. We release JudgmentBench, a benchmark of 30 real-world legal tasks, paired with 1,539 rubric scores and 1,530 pairwise preference judgments collected from practicing attorneys--including at major U. S. law firms--with substantial experience.
