If you need more proof that AI detectors fails in education, this paper makes the case so simple and clear.
如果你需要更多证据证明AI检测器在教育领域失效，这篇论文将问题阐述得既简单又清晰。
These "AI detectors" tools are conceptually unsound because, in real student work, there is no independent ground truth to verify whether a flag was actually correct.
这些“AI检测器”工具在概念上站不住脚，因为在真实的学生作业中，不存在独立的基准真相来验证某个标记是否确实正确。
Even a detector with a perfect record on false positives would still fail, because the students it misses are the ones skilled enough to disguise their output. What ends up being punished is not AI use but clumsiness at hiding it.
即使一个检测器在误报方面表现完美，它仍然会失败，因为它漏掉的学生恰恰是那些擅长伪装其输出的学生。最终受到惩罚的不是使用AI，而是掩饰AI使用的笨拙。
A detector's accuracy rate tells you nothing about whether any particular flag it raises is correct.
检测器的准确率并不能告诉你它提出的任何特定标记是否正确。
Turning that rate into a probability about any one flagged case needs the base rate, which is unknowable.
将该比率转化为关于任何单个被标记案例的概率，需要基础率，而基础率是不可知的。
So a classifier deployed where ground truth is never observable cannot settle an individual case, only justify a closer look.
因此，在基准真相永远无法观察到的环境中部署的分类器无法解决单个案例，只能证明需要进一步审查。
Detectors measure something real on labelled corpora, but this paper argues the measurement cannot travel into settings where nothing confirms authorship.
检测器在标注语料库上测量的是真实的东西，但本文认为这种测量无法迁移到没有确认作者身份的环境中。
Even a detector with no false positives does not fix this: in the paper's hypothetical, such a tool cleared 27 papers of which 11 were entirely AI-generated.
即使一个没有误报的检测器也无法解决这个问题：在论文的假设情境中，这样的工具清除了27篇论文，其中11篇完全由AI生成。
