US Experts Warn AI Writing Tools Weaken Students' Critical Thinking Skills

Cognitive psychologists and education experts warn that students' growing reliance on AI for writing tasks bypasses the mental effort required for cognitive development. A recent MIT study highlighted this by showing that students using AI to write essays exhibited lower brain activity and struggled to recall their own writing. Writing is not just recording thoughts but a cognitive exercise that trains working memory, planning, and metacognition. Outsourcing this process to AI could permanently degrade students' ability to form independent judgments, prompting schools to restrict AI and return to traditional paper-and-pencil exams. The MIT study revealed that even when forced to write without AI assistance later, participants who had previously relied on AI continued to show lower levels of brain activity. In response, universities like Princeton are revising honor codes and eliminating unproctored exams to curb AI dependency.
