The Power of Collective Memory and Visual Design in Shaping Society and User Experience

In a world where attention is fleeting and information overload is the norm, the concept of collective memory becomes increasingly important. According to David Eagleman, a person only truly dies when they are forgotten. This notion suggests that our lives can live on in the minds of others, shaping their lives and being passed on to future generations. But how does this relate to mathematics and the choices we make in remembering certain people and events?

A recent study published in Nature Human Behavior explored the relationship between attention and memory. By analyzing online views of Wikipedia profiles, citations of physics papers, patents, and online play counts of songs and film trailers, researchers found that collective memory follows a mathematical law. The study revealed that collective memory dropped quickly at first, but then declined at a much slower pace. This decline can be best described by a biexponential function, which has two phases.

The initial steep decline is dominated by communicative memory, which is the direct transfer of information through word-of-mouth. This phase represents the immediate impact of an event or person and is influenced by the level of attention it receives. On the other hand, the second phase relies more on cultural memory, which is sustained by the physical recording of information. This phase is characterized by a gentler slope and is influenced by accessibility and searchability.

Interestingly, music showed the shortest and sharpest initial decline in attention, taking only six years, while the online biographies of sports stars had the longest decline, lasting between 20 to 30 years. This discrepancy highlights the varying levels of attention and cultural significance given to different forms of media and individuals.

Drawing a parallel to the decay of collective memory, Chilean writer Pablo Neruda eloquently stated, "Love is so short, forgetting is so long." This poetic description captures the essence of how memories fade over time, but also how certain memories can endure through the recording and preservation of information.

Moving beyond the realm of collective memory, visual design plays a crucial role in shaping user experience (UX). Humans are naturally drawn to things and people they find aesthetically pleasing. Numerous studies have shown that attractiveness influences trust, with both adults and children more likely to trust someone they find attractive. This phenomenon extends to digital interfaces as well.
