Recently, a significant mistake surfaced in a weekly real estate industry report, co-authored by two analysts. The report erroneously cited a statement on real estate from the 2024 State Council executive meeting as the most recent policy, dated June 7, 2026. Industry experts noted that this type of error—a mix of 'temporal misalignment and verbatim content duplication'—is a hallmark of AI large model 'hallucinations'. It's reported that this blunder arose because the analysts or the underlying large model fell prey to 'information pollution' while scraping publicly accessible data from the internet. This caused the AI to erroneously project outdated news into the present context without rigorous verification. At present, AI mainly serves a supplementary function in crafting research reports. However, the infiltration of misinformation from the internet into professional research through AI tools is a concerning trend that demands our attention and caution.
