Neuroaesthetics: The Human Evolutionary Preference for Symmetry and Luster
From The Observatory
Humans have a long-standing attraction to beauty, particularly in symmetry and glossy, shiny surfaces, a preference rooted in our evolutionary history. Early humans who could recognize water sources had a survival advantage, and this ability shaped our aesthetic preferences. Neuroscience shows that our brains process beauty through three interconnected systems: one that handles emotion and reward, one that interprets visual patterns, and one that gives meaning based on past experiences. These systems help us quickly recognize symmetrical forms, which are pleasing and efficient to process, and may have been crucial for identifying healthy mates or spotting animals. Even infants can detect mirror symmetry, suggesting it is an inborn ability. Evidence from prehistoric tools, like Acheulian handaxes, shows that early humans intentionally crafted symmetrical objects for aesthetic purposes, not just functionality.
Similarly, humans are drawn to lustrous, glossy surfaces. Experiments show both adults and children prefer glossy images over matte ones, indicating an innate attraction. This preference is linked to the importance of water in human evolution: shiny surfaces signal moisture, a vital resource for survival. Studies also suggest that viewing water can reduce heart rate and blood pressure, creating a calming effect. Archaeological findings, such as polished gravels in Upper Paleolithic France and Aurignacian ornaments in Europe, reveal that prehistoric humans deliberately selected shiny materials like ivory, amber, and mother-of-pearl for decoration, ritual use, or personal enjoyment.
These evolutionary preferences continue to influence modern life. People are drawn to homes near water, landscapes with lakes or rivers, and shiny, reflective surfaces in design and marketing. Understanding why humans are attracted to symmetry and luster can help architects, designers, and mental health professionals create environments that promote relaxation, well-being, and aesthetic satisfaction. By connecting evolutionary science, archaeology, and neuroscience, we see that our appreciation of beauty is more than cultural—it is deeply embedded in the human brain and history.
