Cognitive Death: The Negative Impact of AI
Human civilisation has always been shaped by the tools it creates. However, the arrival of generative Artificial Intelligence (AI) brings a radically different leap. AI is no longer merely a mechanical aid, but an external cognitive partner capable of imitating, accelerating, and even replacing human reasoning processes. Amidst all the efficiency it offers, an existential threat begins to loom over us: the phenomenon of ‘Cognitive Atrophy’, a condition in which humans voluntarily surrender their critical thinking authority and creativity to algorithms.
Historically, cognitive psychology has viewed technology as a means to reduce mental burden. However, current reality shows a worrying direction. The human brain biologically tends to choose the most energy-efficient route (cognitive miser). When the barrier to obtaining instant answers becomes zero, humans begin to skip the crucial thinking process: the healthy cognitive frustration involved in solving problems.
According to a study from Harvard University, the loss of this barrier eliminates productive struggle, which the brain actually needs to form analytical sharpness. As a result, humans experience de-skilling or a massive decline in thinking expertise.
The destructive impact is no longer merely an assumption, but an empirically measurable reality. An experimental study by the MIT Media Lab using EEG recordings showed that users’ neural connectivity decreased by nearly half when writing essays with the help of generative AI. Their brains showed the lowest level of brain engagement. In line with this, large-scale research published in the MDPI journal (Societies) confirms a significant negative correlation between the frequency of AI use and critical thinking ability, especially among younger generations who are most vulnerable to total mental dependence.
Furthermore, this dependence triggers the phenomenon of digital amnesia. Research shows that most AI users are unable to recall material that has just been generated by the machine. Long-term memory weakens because the brain knows the information is always ready to be accessed again without needing to be stored.
Cognitive death is a high price to pay if humans exchange the essence of their humanity—namely the complex and arduous process of thinking—for instant comfort.
To prevent the death of reason, AI must be positioned as an initial spark, not the final determinant of decisions. The future of our civilisation is not determined by how intelligent the machines we create are, but by how persistently we maintain the sharpness of our intellect (authenticity) in the face of those machines.
