"A study by the Massachusetts Institute of Technology used electroencephalography (EEG) to monitor the brain activity of essay writers given access to AI, search engines like Google, or nothing at all. Those who could rely on AI showed the lowest cognitive activity and struggled to accurately quote their work. Perhaps most concerning was that over a couple of months, participants in the AI group became increasingly lazy, copying entire blocks of text in their essays.''
