The 2023 IgNobel Prize-winning research presents a truly intriguing phenomenon: the “never see you,” is the opposite of déjà vu.
Published in the journal Taylor & Francis Online, this research raises fascinating questions about our memory and how the brain can surprise us, often for an important purpose.

Many people may have experienced the disconcerting sensation of feeling like they are reliving a familiar moment, known as déjà vu.
On the other hand, this peculiar — and common — cerebral phenomenon has an equally interesting counterpoint, “jamais vu”. It may seem new because of the term, but we have no doubt that you have already experienced it.
How does “jamais vu” work?
Unlike the feeling of reliving a familiar moment, when we spend a lot of time observing or repeating something familiar, we gradually begin to feel that that moment loses its meaning.
Researchers believe that such phenomena are related to our memory processing and the way our brain deals with familiar information.
Although the feeling of “jamais vu” is not as common as déjà vu, researchers have managed to find a way to stimulate the phenomenon in a laboratory setting.
The research team, led by Akira O’Connor from the University of Saint Andrews in Scotland, and Christopher Moulin, from the University of Grenoble-Alpes in France, dedicated 15 years to experimental studies before publishing his findings.

Our brain's ability to make associations is extremely important, as it is through these relationships that we form new memories and understand the world around us.
However, research on “jamais vu” leads us to reflect on what would happen if we were unable to process repetitive information or usual situations efficiently.
Scientists are exploring the possible link between the phenomenon of “jamais vu” and conditions such as obsessive-compulsive disorder (OCD).
The theory is that excessive repetition of checks, such as whether the door is locked or not, can lead to the brain not storing everyday information properly.
This, in turn, could trigger an endless cycle of observations, in which the more times something is consulted, the less processing the information becomes. information.
