University caught out using AI to wrongly accuse students of cheating with AI

"Around one-quarter of all referrals were dismissed following investigation, and any case where Turnitin's AI detection tool was the sole evidence was dismissed immediately."

Then why the fuck is your institution using it? This costs money, yes? And you use it to ensure academic integrity? But the results are insufficient to punish anyone? So you are paying money for literally nothing???

How stupid is this
