What Happens When You Use ChatGPT to Write an Essay? New Study Findings

A recent MIT study reveals that using ChatGPT for essay writing may hinder cognitive function and creativity. Participants who relied on the AI displayed lower brain activity and produced less original work compared to those who wrote without any tools. The research raises concerns about the cognitive costs associated with integrating AI in educational settings.

A new study from MIT raises questions about using AI, specifically ChatGPT, for writing essays. While the chatbot can generate text quickly, researchers found its use may hinder cognitive function. The MIT Media Lab study, involving 54 participants, discovered that those who relied solely on ChatGPT showed both lower brain activity and less originality in their writing compared to individuals using no tools at all.

The team, led by research scientist Nataliya Kosmyna, recruited individuals aged 18 to 39 from esteemed schools like MIT and Harvard. Participants were divided into three groups: one using ChatGPT, another relying on traditional search engines, and a third writing without any external tools. Each was tasked with crafting an essay based on prompts derived from SAT tests, all within a tight 20-minute window.

For instance, one prompt asked if true loyalty sometimes requires critique, challenging the notion of unconditional support. As participants wrote, they wore a special Neuoelectrics headset to capture their brain’s electrical signals and activity. This allowed researchers to analyze cognitive engagement as they produced their essays. Post-task, some participants switched groups: previously tool-using writers now wrote without tech and vice versa.

When it came to the quality of essays, those written without support displayed more variety in topics, vocabulary, and structure. In contrast, ChatGPT-assisted essays tended to be more uniform and predictable. Four trained English teachers, tasked with judging the essays, noted a distinct lack of personal touch in those composed with AI assistance. “These essays felt ‘soulless’, lacking personal nuances,” they stated.

Interestingly, AI judges scored many essays well, averaging a four on a five-point scale. But, the stark difference in human perception underscores potential issues with AI-generated content.

Now, regarding the brain activity findings, researchers observed that those who wrote without tools exhibited the most robust brain engagement. The study pointed out that the ChatGPT group experienced a remarkable 55% reduction in brain activity compared to their unaided peers. Participants using only search engines fared better than those with ChatGPT, displaying more eye movement, a gauge of cognitive engagement even while using digital screens for research.

Moving forward, the MIT study underscores the need for further examination of how AI impacts cognitive abilities. Researchers emphasized that including more diverse participants and exploring AI usage beyond traditional educational frameworks could lead to more comprehensive insights. As AI continues to permeate various aspects of our lives, understanding its cognitive cost is crucial for educators and students alike.

The MIT study highlights significant concerns about using AI like ChatGPT for essay writing. While the tool can produce written content quickly, reliance on it may lead to diminished cognitive engagement and originality. The researchers call for more studies to understand these effects fully, considering broader participant demographics and contexts. As AI tech evolves, it’s more important than ever to monitor its implications on learning and critical thinking.
