Study Suggests AI Usage May Lower Brain Activity, But Impact on Intelligence Is Complex

A recent study from MIT Media Lab suggests that AI tools reduce brain activity in users, raising concerns about cognitive decline. However, the essence of the findings points to the importance of how individuals engage with AI. Responsible use of technology may enhance our cognitive abilities rather than diminish them, urging a reevaluation of our approach to these tools.

In the wake of an MIT Media Lab study, many are wondering whether AI tools, like ChatGPT, are actually making us dumber. The research reveals that the use of AI can lead to reduced brain activity, but that’s not the whole picture. How we engage with these tools is crucial; it’s not just about using AI, but how we choose to utilize it within our thought processes.

The study involved 54 students who wrote essays under three different conditions: using their own cognitive skills, employing a simple search engine, or relying on ChatGPT. Over three weeks, participants rotated through these methods, while their brain activity was monitored with EEG headsets. Essays were evaluated both by humans and AI. The results were telling: those who wrote manually had a greater sense of ownership and engagement with their work, often recalling details far better than their AI-using peers.

Initially, AI users struggled with memory and coherence in their essays. When switching to manual writing, they still didn’t shine as much as others who had engaged more directly with the writing process. It’s a bit alarming, sure, but the researchers themselves noted that these results haven’t been peer-reviewed, and that the focus was narrow, limited to just essay writing. The key takeaway some might grasp is that AI may dumb us down — but could there be a different lens?

Let’s think about this. AI can be a tool to support thought rather than replace it. Consider if you’re using AI to draft an email or if you’re simply offloading your thinking entirely. Many forget that AI models don’t think—at least not in the human way. They’re programmed to mimic patterns, not reason.

The MIT study failed to address the critical difference between thoughtful use of AI and mindless copying. The students’ behavior—their tendency to use AI for everything without much thought—likely diluted their engagement. The cognitive costs of AI interaction might be more about how it’s used rather than AI’s inherent presence.

For example, just as we no longer memorize phone numbers like we did before cell phones became prevalent, our cognitive patterns shift with the tools we adopt. This shifting dynamic of intelligence encompasses much more than just memorization; it’s about learning where and how to seek information effectively and using that knowledge when required.

We must recognize that every new technology—from calculators to the internet—has sparked fears of diminishing intelligence. And likewise, the emergence of AI should encourage us to consider how we engage with it. Are we letting it do the thinking, or are we integrating it into our processes to enhance our cognitive capabilities? If used wisely, AI could lead to improved collaborative efforts between human intuition and machine logic.

Just as the study indicated, the LLM group’s lower engagement was less about actual memory deficits and more about a failure to connect with their written work. If they felt detached from their writing process because they weren’t the driving force behind their words, it raises questions about learning and growth. In short, AI can’t— and shouldn’t—replace the hard work behind creative processes.

While the research indeed highlights the importance of engagement with our tools, suggesting that thoughtfulness in adopting AI is vital. We should aim to enhance our cognitive skills rather than defaulting to AI as a crutch. The future of technology isn’t humans versus AI; it’s about cultivating our ability to think alongside these powerful tools. If we play our cards right, we’ll all keep our brains sharp in this evolving landscape.

The MIT study prompts important questions about our relationship with AI and cognitive engagement. It’s clear that while AI can reduce brain activity, what really matters is how we choose to interact with these tools. The real issue is not AI dumbing us down, but whether we’re tapping into its capabilities thoughtfully. Embracing technology should mean enhancing our intelligence, not bypassing the hard work of critical thinking. As we move forward, it’s about harmonizing human thought with AI efficiency.
