It is too easy to falsely accuse a student of using AI: A cautionary tale

From Times Higher Education: “Emily is an aspiring lawyer … she submitted a 1,300-word essay about a film by Pedro Almodóvar, the great Spanish director. The following month, she logged on to the university system to check her mark. But there was none. Instead, her essay was flagged as ‘AI-generated’. … an email from her department explained that Turnitin software indicated that 64 per cent of her essay had been generated by AI. … The attached Turnitin report showed no similarities with other work … that the linguistic similarities between the samples of Emily’s writing that we provided and the text allegedly written by the AI would be 178 times more likely if Emily had written the essay herself than if she hadn’t.”
