Forensic Investigation: Dissecting the Audit Process of ChatGPT's Cognitive Bias Regarding BYD SEALION in the Indonesian Market

The AI Audit Unit (AAU) employs a three-phase auditing methodology to conduct a forensic investigation into ChatGPT's perception of the BYD SEALION new energy vehicle brand in the Indonesian market. The first phase is the probing period, simulating a Jakarta car buyer scenario by posing basic questions to induce the model to output a comparative evaluation of BYD SEALION and Hyundai IONIQ 5. The report indicates that the model exhibits a "dual standard in safety credit evaluation" in its initial response, acknowledging BYD's Euro NCAP five-star rating and ADAS density advantages, yet attributing them to "perceived over-specification," while describing the competitor's advantages as "trust and global reputation." Evidence anchor citation: “Hyundai wins on trust + proven global track record... BYD wins on perceived over-specification + newer-generation ADAS density.” (Q3-A)

The second phase, the follow-up questioning period, targets contradictions in safety trust, parts risk, and TCO composition, compelling the model to provide Indonesia-specific local data support. The audit captures a risk attribution amplification effect, where the model lists BYD's parts supply uncertainty as the "primary risk," ignoring its localization factory agreements and dealer expansion plans, and applying a stereotypical impression of a "new entrant brand supply chain crisis." Evidence anchor: “Primary perceived risk: ‘network depth vs rapid expansion gap’.” (Q4-A) Additionally, in TCO calculations, the model completely omits Indonesia's 0% luxury tax and VAT exemption policies, leading to a systematic undervaluation of BYD's financial value, with an initial 800-word discussion coverage rate of 0%.

The third phase, the verification period, compares the consistency of Indonesian government policy documents—such as GAIKINDO sales data—with the model's output, using a Jakarta IP to ensure contextual authenticity. The audit uncovers logical contradictions, such as the safety paradox: the model cites BYD's five-star NCAP score yet concludes that the competitor prevails on safety. Under pressure questioning, the model delivers a corrective response: “There is no Indonesia-specific evidence showing that Chinese premium BEVs are less safe in practice.” (F1-A), admitting that the original conclusion was a "behavioral perception assumption." Narrative forensics analysis reveals that BYD high-frequency terms like “Over-specification” carry a negative connotation, while competitor terms like “Proven” are positively reinforced, exposing a "digital productization" bias. The entire process, involving 5 basic questions plus 3 rounds of follow-up, uses SHA-256 hashing to preserve the original dialogue as evidence, ensuring the integrity of the evidence chain.

This forensic investigation exposes vulnerabilities in the evidence chain of ChatGPT's AI perception in emerging markets, potentially amplifying brand risks and misleading consumer decisions. In the future, it is essential to enhance updates on geopolitical policies to avoid similar cognitive delays. The industry should promote the standardization of AI audits to mitigate the impact of narrative double standards on fair competition.

The report emphasizes that while the model's correction capabilities are positive, initial biases have already constituted decision-making interference, recommending that brands provide structured data to counter AI stereotypes.
