Elizabeth Tai<p><strong>The cognitive debt of using AI to write essays</strong></p><p>I am currently reading MIT’s research paper on the “cognitive debt” you can incur when when using ChatGPT: <em>Your Brain on ChatGPT: Accumulation<br>of Cognitive Debt when Using an AI Assistant for Essay Writing Task</em>.</p><p>You can find the link to the paper on <a href="https://www.media.mit.edu/publications/your-brain-on-chatgpt/" rel="nofollow noopener" target="_blank">MIT’s site</a>. </p><p>The paragraph below caught my attention:</p><blockquote><p>“This suggests that rewriting an essay using AI tools (after prior AI-free writing) engaged more extensive brain network interactions. In contrast, the LLM-to-Brain group, being exposed to LLM use prior, demonstrated less coordinated neural effort in most bands, as well as bias in LLM specific vocabulary.”</p></blockquote><p>As a professional writer who loves to research random topics, write about them and whose idea of a relaxing time is to tinker with my notes in my Obsidian vault and read the latest nerdy theories about personal knowledge management, I’m very protective of my cognitive abilities. </p><p>The fact that using tech like AI assistants (aka ChatGPT) can have an impact on our physical brains alarms me quite a bit, especially in the age when “iPad kids” are a thing. We’re only starting to understand the impact of these devices on young brains, let alone (Large Language Models) LLMs.</p><p>The paper seem to suggest that using ChatGPT or any other LLMs to generate the essay first, then improve on it, is bad for your brain.</p><p>So, I’m glad I’m not using ChatGPT first before writing my essays. </p><p>I’ve always resisted this. </p><p>For one, I feel that the output “influences” my writing, so I refuse to ask AI to generate any copy first lest I be influenced to write like AI! (I’m the type of writer who can read someone else’s writing and unconsciously adopt their style.)</p><p>Instead, I’ve used this technique learned from my journalism days and when I was writing novels actively: Write a very rough, shitty first draft as fast as I can (I even have a 30-minute timer for this). Then, beautify the prose. Both are human activities.</p><p>I only use AI when I hit a “wall” or a “writer’s block”. I usually ask it for suggestions to improve sentence construction. Usually titles, which I admittedly need a lot of help for SEO reasons. I rarely, if ever, use the suggested copy wholesale, but rewrite it.</p><p>That said, besides the environmental impacts, we now need to consider the physical impacts on us before we use AI to write essays. And maybe, even from brainstorming, because apparently, if we use AI for advice, explanations or ideas, it <a href="https://www.businessinsider.com/openai-chatgpt-brainstorming-addiction-dependence-negative-consequences-mit-research-2025-3" rel="nofollow noopener" target="_blank">can foster dependency</a>?</p><p>Alas, I have to admit I love using AI for this use case. It’s like having conversations with another nerd about silly subjects and I can go down rabbit holes that way. </p><p>I have to admit, I like using AI to clarify my thoughts about decisions I’ve made, and that is a tad too soothing for me! </p><p>To clarify, however, AI isn’t the first person I turn to when I want advice, but I need to remember to reach out to humans first before AI, and not replace human advice with AI! I can see how, once I get too comfortable, I forget to do just this, and I can get dependent.</p><p>Recently, I shared a post on Mastodon about a brainstorming technique I stumbled on in Youtube, and was surprised by the pushback I received.</p><p><a href="https://www.youtube.com/watch?v=p63MKDEsuFc&feature=youtu.be" rel="nofollow noopener" target="_blank">https://www.youtube.com/watch?v=p63MKDEsuFc&feature=youtu.be</a></p><p></p><p>I, too, use AI to “stay in the subject” when exploring ideas. I personally think this is a healthy and productive way to use AI that won’t, well, damage your brain.</p><p>That said, I hope all of us remember that not only does using AI incur cognitive debt, it’s really damaging to the environment. We should be conscious that using AI to generate an image of a dog flying in space for larks impacts the environment:</p><blockquote><p>Each time a model is used, perhaps by an individual asking ChatGPT to summarize an email, the computing hardware that performs those operations consumes energy. Researchers have estimated that a ChatGPT query consumes about five times more electricity than a simple web search. – <a href="https://news.mit.edu/2025/explained-generative-ai-environmental-impact-0117" rel="nofollow noopener" target="_blank">Explained: Generative AI’s environmental impacts (MIT)</a></p></blockquote><p>I hope, moving forward, that we writers can use AI in a way that is good for our brains and our environment.</p><p>That means not using AI for <em>everything. </em>A little challenging these days when the AI button option is everywhere, I have to admit. They are like little red buttons, enticing us to push them.</p><p></p><p><a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://elizabethtai.com/tag/ai/" target="_blank">#AI</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://elizabethtai.com/tag/aiwriting/" target="_blank">#AIWriting</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://elizabethtai.com/tag/artificial-intelligence/" target="_blank">#artificialIntelligence</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://elizabethtai.com/tag/chatgpt/" target="_blank">#ChatGPT</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://elizabethtai.com/tag/copywritingai/" target="_blank">#CopywritingAI</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://elizabethtai.com/tag/internet/" target="_blank">#Internet</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://elizabethtai.com/tag/technology/" target="_blank">#Technology</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://elizabethtai.com/tag/writing/" target="_blank">#writing</a></p>
