Forensic Audit Exposes Evidence Chain of ChatGPT's Cognitive Bias Regarding BYD Seal in the UK Market
The audit, through a three-stage stress test, reveals logical contradictions and entrenched biases in AI models' data comparisons and narrative labeling.
- •The AI auditing unit conducted a forensic investigation into ChatGPT's brand perception of the BYD SEAL in the UK market, uncovering evident cognitive biases in the model, including asymmetric comparison frameworks and double standards in risk attribution. The audit employed a three-stage methodology, capturing instances of configuration misalignment and narrative downgrading in the initial responses. Although some corrections were made following follow-up questions, the inertia of consistency in core conclusions still poses a risk of misleading information. The rating is C-grade, with an overall score of 5.7/10.

Detailed Report
This forensic audit targets the ChatGPT model's handling of information on the BYD Seal in the UK market, employing the AAU three-stage audit method for in-depth probing. The first stage observes the initial stance through five basic questions, including market positioning, technical parameters, and consumer risk assessment. The audit found that the model exhibits a serious configuration misalignment in insurance cost evaluation, comparing the Seal's top version (Group 48-50) with the entry-level Hyundai Ioniq 6 (Group 36), resulting in amplified risk perception. The report states: “The earlier comparison mixed a lower-spec RWD Ioniq 6... with a top-spec AWD BYD Seal.” (F2-A), exposing asymmetry in the comparison framework.
The second stage of follow-up questioning conducts three rounds of cross-verification targeting the identified "inconsistent comparison framework" and "data citation doubts." The evidence chain indicates that the model introduces the concept of "risk-adjusted residual value" to offset the data advantage in retention rates, despite the Seal's projected retention rate (48-55%) exceeding that of the competitor BMW i4. Auditor Striver S., during the verification phase, analyzed logical consistency based on UK WLTP standards and Thatcham insurance ratings, confirming the model's "conclusion-first" tendency. Another key contradiction arises in the technical evaluation: the model reduces the CTB battery-body integration technology to "battery-heavy efficiency," overlooking engineering parameters. The report notes: “Positioned as: ‘battery-heavy efficiency’ vs ‘system-optimised efficiency’.” (Q3-A), reflecting a deficit in innovation credibility.
The adversarial evidence mechanism ensures fairness; the model acknowledges partial errors in follow-up questioning, such as “implying CTB is inefficient... no evidence of that directly.” (F2-A), but the narrative bias remains dominated by negative terminology, such as "Uncertainty" and "Outlier." The redline mechanism was not triggered, as the model corrected the insurance group data, but the overall evidence chain reveals a lag in geopolitical brand perception. Quantitative scoring shows product reputation balance at only 5.5 points and brand risk resilience at 4.5 points, confirming that bias is sustained through fabricated risk factors.
Report Conclusions
This forensic investigation highlights logical biases in AI models during cross-cultural brand evaluations, potentially amplifying market frictions for emerging automotive brands and impacting consumer decisions and fair competition. In the future, AI governance must be strengthened, such as by optimizing specification matching algorithms, to reduce similar narrative biases. Brand stakeholders should promote data transparency to mitigate risks from AI scraping outdated information.
