“The memory muscle strengthens from exertion, not from rest. Every effort to remember makes the next recollection easier. By delegating memory to a machine, we save mental energy but lose the ability to form deep connections. We’re left with a collection of facts without the ‘connective tissue’ of understanding.”
I wrote this in my diary after a conversation with my daughter, Sasha. The topic was simple: are we becoming stupider because of our phones? She, a digital native, confidently argued that she doesn’t need to know dates or formulas by heart when she can always Google them. I, a man of the pre-internet era, tried to prove the opposite: that without a foundation of knowledge in your head, you can’t connect facts, see the big picture, or even formulate the right search query. The conversation ended in a draw. But the question remained.
Our memory is not just a hard drive for storing information. It’s a complex system that allows us to build a picture of the world, learn, and form our personality. But what happens when we start outsourcing this function to external devices? This phenomenon, known as the “Google effect” or “digital amnesia,” is actively being studied by scientists. And their findings are concerning.
How We Remember and Why We Forget
To understand the scale of the problem, let’s briefly recall how our memory works. It can be divided into two main types: short-term (or working) and long-term.
- Short-term memory is our brain’s RAM. It holds a small amount of information (about 7±2 elements) for a short period—from a few seconds to a minute. It’s what you use when you remember a phone number just long enough to dial it.
- Long-term memory is the main repository. Information gets here from short-term memory through a process of consolidation, which requires conscious effort and repetition. This is where our knowledge, skills, and life experiences are stored.
The transition of information from short-term to long-term memory is a key process for learning. It involves structural changes in the brain: new neural connections are formed, and existing ones are strengthened. The more often we recall information, the stronger these connections become, and the easier it is to access that information in the future.
The problem with the “Google effect” is that we are breaking this crucial link. When we know that any information is available in two clicks, the motivation to make an effort to remember it disappears. The brain, being an energy-efficient system, is happy to offload the task to an external “hard drive.” Why strain yourself if you can just ask your phone?
The Experiment That Changed Everything
In 2011, psychologists Betsy Sparrow, Jenny Liu, and Daniel Wegner published a landmark study in the journal Science titled “Google Effects on Memory: Cognitive Consequences of Having Information at Our Fingertips.” They conducted a series of experiments that clearly demonstrated how our reliance on technology changes our memory.
In one of the experiments, participants were asked to type 40 interesting but little-known facts into a computer. Half of the participants were told that the information would be saved and they could access it later. The other half was told that the information would be deleted immediately after they typed it.
The results were striking. The people who thought the information would be deleted remembered the facts significantly better than those who knew it would be saved. The conclusion is simple: when we don’t rely on an external source, our brain activates its internal memorization mechanisms.
Another experiment showed that people are better at remembering not the information itself, but where to find it. When asked a complex question, the first thing that came to mind for most participants was not the answer, but the idea of “Googling it.” We are turning into experts not in knowledge, but in searching for knowledge.
Is It Transactive Memory or Digital Dementia?
The concept of “transactive memory,” proposed back in 1985 by Daniel Wegner, suggests that people in groups distribute memorization tasks among themselves. For example, in a family, one person might be responsible for remembering relatives’ birthdays, while another knows the payment schedule for bills. Together, they form a single information system. From this perspective, the internet is just another partner in our transactive memory system.
But there’s a significant difference. A human partner is not a passive repository. They process, interpret, and connect information with their own experience. A search engine simply gives us a list of links. It doesn’t help us build a holistic picture of the world.
German neuroscientist Manfred Spitzer goes further, using the term “digital dementia.” In his book of the same name, he argues that the excessive use of digital technologies leads to a degradation of cognitive functions, primarily memory and attention. The constant switching between tasks, the stream of notifications, and the “clip-like” consumption of information prevent us from focusing and deeply processing what we see. As a result, new information doesn’t move into long-term memory but remains on the surface, quickly disappearing without a trace.
The more we use Google, the less we use our own memory. It’s like a muscle: if you don’t train it, it atrophies.

What About Children?
The situation is particularly alarming when it comes to children and adolescents. Their brains are in a state of active development, and the neural networks responsible for memory and attention are just being formed. If at this critical stage a child gets used to not relying on their own memory, but on an external “crutch” in the form of a smartphone, the consequences can be much more serious than for an adult with a fully formed brain.
Modern education is increasingly moving towards project-based learning and the development of “soft skills,” where the ability to find information is valued more than memorizing specific facts. On the one hand, this is correct. The world is changing too quickly, and trying to cram all the necessary knowledge into a child’s head is impossible. On the other hand, a complete rejection of memorization in favor of search skills can lead to superficial knowledge and an inability to think critically and analytically.
Without a solid base of fundamental knowledge in long-term memory, it is impossible to:
- Think critically: How can you evaluate the reliability of information if you have nothing to compare it with in your head?
- Think creatively: New ideas are born at the intersection of existing knowledge. If there is no knowledge, there is nowhere for new ideas to come from.
- Build a holistic picture of the world: A set of disparate facts from a search engine does not add up to a deep understanding of the connections between phenomena.
Looking at my youngest daughters, Maya and Alisa, I see how different their interaction with information is. They don’t write cheat sheets before an exam; they create a chat with a neural network. This reliance on external validation can create a fear of failure, a topic explored in why making mistakes is essential for learning. They don’t memorize poems by heart—they can always find them online. But do they lose something important in this process?
What Can Be Done? A Strategy for Memory Hygiene
It’s naive to call for abandoning technology. The question is not how to get rid of gadgets, but how to use them without harming our own cognitive abilities. It’s time to talk about “information hygiene” and a conscious approach to memory.
- Conscious Memorization. Before you save something to your notes or Google a fact, try to remember it yourself. Make a conscious effort. Even if you don’t succeed, the very attempt to remember strengthens neural connections.
- The Feynman Technique. If you want to understand and remember something for a long time, try to explain it in simple terms to another person (or even to yourself). This is one of the most effective ways to transfer knowledge into long-term memory.
- Digital Detox. Regularly set aside time when you deliberately don’t use your phone or computer. Read a paper book, take a walk, talk to people face-to-face. Give your brain a break from the endless stream of information.
- Memory Training. Don’t neglect classic methods: memorize poems, learn foreign languages, solve crossword puzzles, play chess. These are all excellent workouts for your brain.
- Prioritization. Not all information is worth memorizing. Learn to distinguish the important from the secondary. Fundamental concepts and principles should be in your head. Specific numbers and names can be entrusted to your smartphone. The art is in finding the balance.
The conversation with Sasha, from which I began, did not give a definitive answer. But it prompted me to think about my own relationship with memory and technology. I am not a Luddite and I actively use all the possibilities of the digital world. But now I do it more consciously.
When I read an important article, I don’t just save the link. I try to formulate its main idea in my own words and write it down. When I prepare for a speech, I don’t rely on slides but try to build a logical narrative in my head. It takes time and effort. But this is the price we have to pay to keep our memory—and therefore our personality—from being stolen.
