3. A computer model created by researchers can detect ChatGPT-generated fake studies with great accuracy,a new study shows.This implies that although the artificial intelligence(AI)chatbot ChatGPT may be a decent imitator of human workers in several fields,scientific research is not one of them.
In the new study,published June 7 in the journal Cell Reports Physical Science,researchers created a new computer learning program to tell the differences between real scientific papers and fake examples written by ChatGPT.The scientists trained the program to identify key differences between 64 real studies published in the journal Science and 128 papers created by ChatGPT using the same 64 papers as a prompt.
The team then tested how well their model could distinguish between a group of real papers and ChatGPT-generated papers,which included 60 real papers from the journal Science and 120 AI-generated papers.The program marked the AI-written papers more than 99%of the time and could correctly tell the differences between human-written and chatbot-written paragraphs 92%of the time.
ChatGPT-generated papers differed from human text in four key ways:paragraph complexity,sentence-level diversity in length,punctuation marks and "popular words".For example,human authors write longer and more complex paragraphs,while the AI papers used punctuation that is not found in real papers,such as exclamation marks.
Creating computer programs to tell real papers from AI-generated ones is important because previous studies have hinted that humans may not be as good at spotting the differences and AI is still capable of fooling some humans with its science writing.
The researchers of the new study say they are pleased that their program is effective at weeding out fake papers but warn it is only a proof of concept.Much more wide-scale studies are needed to create better models that are even more reliable and can be trained to specific scientific disciplines to maintain the integrity of the scientific method.
