Is ChatGPT Hurting Your Brainpower? MIT Study Fuels Debate on AI’s Cognitive Impacts

A new study from MIT’s Media Lab suggests that the use of AI language models may have a detrimental effect on learning and critical thinking abilities, especially for younger users. It has sparked debate across the political spectrum.

The Details: The study, which has not been peer reviewed, divided 54 participants aged 18-39 into three groups to write several SAT essays using OpenAI’s ChatGPT, Google’s search engine, and nothing at all. Brain activity was recorded using an EEG, revealing that the ChatGPT group had the lowest brain engagement and performance levels. Participants using ChatGPT also became more reliant on the tool over time. The study has not been peer-reviewed and has drawn criticism for its small sample size. 

Increased Cognitive Laziness: David Brooks (Lean Right bias) argued that while AI offers efficiency, it may discourage critical thinking and long-term intellectual growth. He wrote, “Neurons that fire together wire together. Using a bot to think for you…is empty calories for the mind. You’re robbing yourself of an education and diminishing your intellectual potential.”

‘Too Soon to Tell’: An analysis published by Axios (Lean Left) framed the study as part of a broader, still-unfolding debate about AI's impact on human thinking. It noted society’s recurring pattern of embracing new technology before fully understanding its consequences.

Fostering Loneliness and Reliance: Time (Lean Left) highlighted reports of increased loneliness and lack of originality in writing produced by ChatGPT, quoting two English teachers who called student work “largely soulless.” It also noted that social media users ironically used AI to summarize the MIT study, triggering “AI traps” embedded by researchers, reiterating the increased reliance on AI.
