Your Brain on ChatGPT: Accumulation of Cognitive Debt when Using an AI Assistant for Essay Writing Task – MIT Media Lab (mit.edu)
Cognitive activity scaled down in relation to external tool use….Self-reported ownership of essays was the lowest in the LLM group and the highest in the Brain-only group. LLM users also struggled to accurately quote their own work. While LLMs offer immediate convenience, our findings highlight potential cognitive costs. Over four months, LLM users consistently underperformed at neural, linguistic, and behavioral levels. These results raise concerns about the long-term educational implications of LLM reliance and underscore the need for deeper inquiry into AI's role in learning.
I’ve been concerned about this at work for awhile – reliance on LLMs for writing negatively impacts learning. I see this as sort of a hidden challenge for young lawyers starting out today. So much of our learning comes from writing. If you’re relying on LLMs for your writing, what are you not learning?
Now I have something to support my concerns. Here’s the paper.
