Comment on arXiv:2607.01233: Survivorship Bias in Published-Paper Baselines for Research-Idea Distributions

评论 arXiv:2607.01233:研究构思分布中已发表论文基准的生存者偏差

Abstract: Chen, Zhao, and Cohan introduce a valuable distributional evaluation of LLM-generated research ideas. This comment raises a narrower identification concern: their human baseline consists of published papers, whereas the LLM baseline consists of one-shot proposals. If bridge-like or synthesis-like ideas are relatively easy to generate but relatively unlikely to survive publication, then the published human baseline will understate their prevalence in the unseen human idea pool. The observed human—LLM gap may therefore be partly, or even largely, a consequence of survivorship bias.

摘要: Chen、Zhao 和 Cohan 对大语言模型(LLM)生成的研究构思进行了一项有价值的分布评估。本评论提出了一个更具体的识别问题:他们的人类基准由已发表的论文组成,而 LLM 基准则由一次性生成的提案组成。如果“桥接型”或“综合型”构思相对容易生成,但却不太可能通过同行评审并发表,那么已发表的人类基准就会低估这些构思在未公开的人类构思池中的普遍性。因此,观察到的人类与 LLM 之间的差距,可能部分甚至很大程度上是生存者偏差的结果。
