AI Validative Bias_Rubric Instrument

AI Validative Bias — Rubric Instrument v1.4 (FINAL — Used for Preregistered Analysis) This component contains different versions of Rubric Instrument (v1.1, v1.2, v1.3 and v1.4). These rubric versions developed to assess AI validative bias, defined as a systematic tendency for AI systems to reinforce or affirm user-provided framing, user-provided conceptual material (e.g., terms, claims, or framings)in informational and academic contexts. The rubric evaluates responses across four independent dimensions using observable linguistic markers, focusing on system-level response patterns rather than user effects, factual accuracy, or normative judgments.
