简介
研究发现前沿AI模型比人类写作更频繁使用认知负荷高的语言特征，如物作主语搭配人动作、低频词组等。这解释了为何AI生成内容读起来"不对劲"，对提示工程和产品文案有直接指导意义。
编辑判断
这个发现对做AI产品的人很实际：不是模型变笨了，而是RLHF和指令微调可能意外奖励了"看起来复杂"的输出。之前大家优化可读性主要靠人工标注偏好，这篇论文给出了可量化的语言学指标。
如果你在做客服机器人、文档生成这类对可读性敏感的场景，可以在system prompt里显式约束"避免物作主语""使用高频词组"，效果可能比笼统说"写得自然"更好。论文没有开源代码，但特征提取可以用spaCy和NLTK复现，成本不高。

核心争论：AI文本难懂是真实缺陷还是读者能力问题， fluent readers反而更敏感
I have seen people saying this for a long while now. I don't know how to say this but I understand Ai stuff better than non-Ai. When I see people complain ; I always wonder why because I think that its pretty good with my own senses.. Much much better than my writing skills... My brain has been tun
I think the problem is that LLMs are verbose. They’re like business or self-help books— a lot of filler.
I understand what you are saying but I personally can't tell what it is that people like or dislike other than myself. In a way I accept differences in grammars and assay formation in any which way that is produced but some scientific journals written by humans are unreadable in one pass without re
