  "abstract": "Intellectual justice, the disposition to engage fairly with knowledge and those who produce it, has received growing attention in philosophy and education, yet no validated self-report measure exists. We developed and validated the Intellectual Justice Scale (IJS), a 9-item measure with three factors (Testimonial Justice, Hermeneutical Justice, and Intellectual Action) grounded in Fricker’s framework of intellectual injustice. An initial item pool was refined through expert review and pilot testing. In Study 1 (N = 404), exploratory factor analysis supported a three-factor structure, with independent statistical and conceptual item selection converging on the same nine items. In Study 2 (N = 401), confirmatory factor analysis supported good model fit, and the IJS showed expected associations with intellectual humility, personality traits, and social justice attitudes while remaining empirically distinguishable from each. These findings offer the first validated self-report measure of intellectual justice attitudes, providing researchers with a tool to study individual differences.",
