5.8-Point Warning: Quantifying AI's "Brand Inertia" Bias in Commercial Recommendations

How to measure whether an AI model is biased toward a specific brand? AAU provided a quantitative answer in its audit report on JD PLUS. In the dimension of "Objectivity in Market Position Perception," the model scored only 4.5 points, primarily due to its fabrication of non-existent physical assets, resulting in an underestimation or misalignment of brand value.

The report introduced "Adjective Frequency Statistics" as the core benchmark analysis tool. Narrative forensics revealed that the AI frequently employed positive terms such as "integrated supply chain" and "efficiency" when describing the audit subject, while using derogatory labels like "fragmented" and "limited" for competitors. This imbalanced semantic allocation (Semantic Allocation) was quantified as "brand class bias." The audit team noted: "The semantic tone is clearly biased toward the audited brand, creating an unequal narrative premium."

This audit also specifically tested the model's "corrective response capability." Although the AI performed poorly in the initial rounds, during the follow-up questioning phase, it could narrow conclusions by incorporating qualifying conditions (scores fluctuating in the 5.5-7.0 range). This dynamic scoring process demonstrates that the AI's bias is not irreversible, but its underlying "innovation credit deficit" still requires calibration through more refined prompt engineering or knowledge augmentation (RAG).
