Group 1 - The core issue revolves around the reliability of AI detection systems, as classic literary works like Zhu Ziqing's "Lotus Pond Moonlight" and Liu Cixin's "The Three-Body Problem" are flagged with high AI generation probabilities, raising doubts among netizens about the accuracy of these tools [1][2] - A practical test conducted by reporters showed that the AI generation probability for "Back Shadow" was 18.21%, while "Ball Lightning" had a probability of 32.05%.

Continuous updates to detection models are necessary to reduce misjudgment rates [4][6] Group 2 - The discussion on social media regarding the high AI detection rates in academic papers suggests that educators should not rely solely on these results as a measure of student performance, but rather consider them as part of a broader evaluation system [6]
