All That Glitters is Not Novel: Plagiarism in AI Generated Research

Automating scientific research is considered the final frontier of science.Recently, several papers claim autonomous research agents can generate novel research ideas.Amidst the prevailing optimism, we document a critical concern: a considerable fraction of such research documents are smartly plagiarized.Unlike past efforts where experts evaluate the novelty and feasibility of research ideas, we request 13 experts to operate under a different situational logic: to identify similarities between LLM-generated research documents and existing work.Concerningly, the experts identify 24% of the 50 evaluated research documents to be either paraphrased (with one-to-one methodological mapping), or significantly borrowed from existing work.These reported instances are cross-verified by authors of the source papers.Experts find an additional 32% ideas to partially overlap with prior work, and a small fraction to be completely original.Problematically, these LLM-generated research documents do not acknowledge original sources, and bypass inbuilt plagiarism detectors.Lastly, through controlled experiments we show that automated plagiarism detectors are inadequate at catching plagiarized ideas from such systems.We recommend a careful assessment of LLMgenerated research, and discuss the implications of our findings on academic publishing.
