Artificial intelligence chatbots such as OpenAI’s ChatGPT could be diminishing cognitive ability, according to a recent study by MIT researchers. In a study by researchers from the Massachusetts Institute of Technology’s Media Lab, 54 participants completed essay writing tasks over three sessions using one of three assigned methods and tools: ChatGPT, search engines and only their brains.  In a fourth session, the researchers asked the ChatGPT group to use no tools, and the brain-only group participants were asked to use the LLM.  The results were startling, as they revealed poor memory recall among AI users, with more than 83% of ChatGPT users unable to quote from essays they wrote minutes earlier. Over 80% of LLM participants struggled to quote from their own essays.
