Scientists are beginning to document real changes in the cognitive processes of people who use AI regularly.
A UK study involving 666 participants showed that the more frequently someone uses AI, the weaker their critical thinking becomes. Overreliance on algorithmic suggestions reduces attention span and analytical depth.
MIT Media Lab confirmed this neurologically: people who wrote texts with ChatGPT showed lower brain activity, especially in areas responsible for creativity and memory. Even more striking — 80% of them couldn’t reproduce their own essays without AI’s help.
This doesn’t mean technology is harmful; it means our brains start to relax — like a muscle that stops being trained.Even more striking — 80% of them couldn’t reproduce their own essays without AI’s help.
Experiments at MIT and Stanford found that while AI is great at generating drafts, it also tends to “average out” human thinking.
Essays created with ChatGPT didn’t just sound similar — they were nearly identical. Participants from different countries used the same metaphors, examples, and cultural symbols.
Psychologists call this the cultural smoothing effect: machines learn from massive datasets and produce the most probable, i.e. the most typical outcomes.
So if we rely on AI without adding our own perspective, we risk losing both individuality and boldness of thought.
This is also a challenge for business. A Harvard study found that teams working with AI complete more tasks — but lose intrinsic motivation and get bored faster when the assistant isn’t there.
AI removes the routine, but it also smooths out human initiative.
Here are a few principles to help you stay the “sharp angle” in an automated world:
Start with a task, not a hope.
Don’t just ask AI to “come up with something.” Define clearly what you want to achieve.
Always make your own draft.
Even messy notes kickstart thinking. Don’t delegate the process entirely.
Give yourself five minutes to think first.
This short pause activates your brain and helps form context before you turn to AI.
Don’t take AI’s praise too seriously.
Algorithms don’t judge depth — they reinforce patterns. Ask for critique, not compliments.
Use AI as a partner, not a performer.
Ask it to brainstorm directions or create a mind map, but keep the final word for yourself.
Have AI-free days.
Once a week, work as if ChatGPT doesn’t exist. It’s an excellent way to discipline attention and strengthen creativity.
AI doesn’t destroy thinking — it simply reveals how easily we’re willing to give it away.
Remember: the human brain is still the most powerful processor — but only when it’s switched on.

AI speeds up work but often creates “workslop” - results that look complete yet lack value. Freelancers are the ones turning them into quality.
