Studies suggest that ChatGPT harms critical thinking, diversity of thought |
A series of experiments involving more than 4,500 participants at the University of Pennsylvania’s Wharton School found that those who used ChatGPT and other large language models (LLMs) to research everyday topics demonstrated weaker understanding of those topics afterward and produced less original insights than people who looked up the same topics using Google. Overall, across five experiments, ChatGPT-assisted brainstorming sessions consistently produced narrower sets of ideas, according to the researchers. The findings highlight how overly relying on gen AI “can limit the breadth of perspectives, even when individual ideas seem original,” a media release stated. Relatedly, a study from researchers at MIT’s Media Lab divided 54 subjects - 18 to 39 year-olds from the Boston area - into three groups, and asked them to write several SAT essays using OpenAI’s ChatGPT, Google’s search engine, and nothing at all, respectively. Researchers used an EEG to record the writers’ brain activity across 32 regions, and found that of the three groups, ChatGPT users had the lowest brain engagement and “consistently underperformed at neural, linguistic, and behavioral levels.” Over the course of several months, ChatGPT users got lazier with each subsequent essay, often resorting to copy-and-paste by the end of the study.
