Passive use of AI tools like ChatGPT reduces your brain activity and turns you into a lazy thinker. MIT conducted research on this and the findings are clear. Yet this is no reason to swear off AI. At Hibou, we fully embrace AI, but we view it as a razor-sharp tool, not a comfortable armchair.
In brief:
Brain activity plummets: An MIT study shows that passive use of ChatGPT reduces brain activity by 47%.
‘Decreasing intelligence’: Brain professor Erik Scherder warns that we 'underutilize' our brains and make them lazy when we use AI uncritically
Brain plasticity: Unused neural connections weaken; cognitive challenge, on the other hand, builds resilience.
How to use AI smartly: You are the substantive and creative expert; AI is the tool. Keep those roles separate.
A ‘lazy brain’ is a real threat
Let’s not beat around the bush: yes, the passive, uncritical use of ChatGPT makes us collectively dumber. The MIT research is alarming: you literally put your brain on autopilot and lose altitude in terms of critical thinking and creativity. The result is superficial work that nobody is waiting for.
The science behind cognitive decline
Brain professor Erik Scherder doesn't call AI 'decreasing intelligence' instead of artificial intelligence for nothing. According to him, our brain works simply: the connections (synapses) you use grow stronger. The connections you leave idle weaken. By outsourcing our thinking, we fail to build a complex, resilient brain. That resilience is precisely what is crucial for coping with unexpected problems in life. We 'underutilize' our capacities, a phenomenon Scherder calls underuse.
The problem is not the tool, but the user
But there is another way. The solution is not simply 'writing a better prompt', but making the fundamental choice not to use AI to become lazier. The real gain lies not in speeding up the projects you previously did, but in creating completely new possibilities that were once unthinkable.
Instead of sitting back, at Hibou we use AI as an engine for innovation. Think of developing interactive, AI-driven avatars, or analyzing data for a content strategy that seamlessly aligns with a client's strategic communication choices. This is what switches your brain 'on': not outsourcing your thinking, but solving new, creative, and strategic challenges that AI makes possible.
The evidence: what the MIT research teaches us
The study by the MIT Media Lab hit the nail on the head. Using EEG scans, writers' brain activity was measured across three groups: one that used only their own brain, one with Google as an aid, and one with ChatGPT.
The results were shocking. The ChatGPT group showed the lowest brain engagement. Their essays were generic and interchangeable. As the study progressed, they became lazier. Most disturbing was the 'cognitive debt': when this group later had to write without AI, their brains remained underactive. They had forgotten how to think deeply for themselves.
Take control: from passive consumer to active user
The art is not seeing AI as a magic text generator, but as an intelligent assistant. This is precisely the active, critical attitude that experts like Scherder emphasize. It is the difference between using AI as a sparring partner—where you dig deep yourself and verify the facts—and passively accepting the output.
How to feed the AI with your expertise
That is also how we work at Hibou. Instead of a simple request like “write a blog about X”, we build a detailed prompt incorporating our knowledge:
Structure: We outline the structure of the article, including the function of each paragraph.
Content: We provide the core arguments, facts, and the unique angle we want to highlight.
Tone and style: We define the desired tone of voice and writing style that fits the brand.
By 'training' the AI in this way for each specific task, we ensure that the result amplifies our expertise and creativity, rather than replacing it. Our brain remains fully engaged in the strategic and creative thinking process; the AI helps us with execution.
Use AI as a tool and not as an alternative to your own brain
The threat of cognitive decline caused by AI is real, but it is a choice. Uncritical use inevitably leads to a 'lazy brain'. Active, strategic use—where you contribute your own expertise—not only leads to better results, but also builds the essential cognitive resilience needed. The future does not belong to those who fear AI, but to those who learn to master the tool.
