In recent years, the term «brain decay» has gained popularity when discussing the impact of digital technology on people. Many worry that excessive screen use diminishes concentration, weakens memory, and could even lead to a decline in intelligence quotient (IQ). However, scientific research does not confirm these fears.
For instance, a large-scale study from 2023 involving 120 children found no evidence that time spent in front of screens negatively affects brain function. Scientists did not observe changes in communication between different parts of the brain, nor a deterioration in children’s mental health due to technology. Despite this, many people continue to believe that using electronic devices is harmful to the psyche.
Many publications are based on assumptions rather than actual evidence. For example, one of the most famous theories, which suggests that using emails reduces IQ more than smoking marijuana, turns out to be completely false — it was merely a marketing campaign. Other studies linking the growing popularity of smartphones with deteriorating mental health are also misleading. The fact that two phenomena occur simultaneously does not mean one causes the other.
Moreover, technology has positive aspects. People with fast internet access often feel happier and more socially engaged. Children who use technology for learning achieve better results and are better prepared for the modern world. Scientists emphasize that it’s not the time spent in front of screens that matters, but how it’s used. If someone mindlessly scrolls through social media, it can indeed lead to concentration problems. But if the internet is used for learning or communication, there’s no evidence of harmful effects.
Therefore, the claim that technology destroys the brain is not supported by scientific evidence. It’s more a result of panic and fear of the new. The most important thing is the sensible use of electronic devices: we should control them, not the other way around.
