Indeed! I asked ChatGPT to summarize what is mentioned in the BBC documentary “How Art Made the World” (presented by Dr. Nigel Spivey):
One of the central ideas discussed is that human beings are biologically and psychologically predisposed to find certain forms—especially symmetry and proportionality—more aesthetically pleasing. This idea is supported by a wide body of neuroscientific and psychological research, much of which is referenced or implied in the series.
Here’s a step-by-step explanation of the concept and supporting research:
⸻
1. Symmetry and Biological Attraction
• Symmetry is often associated with health and genetic fitness.
• Studies in evolutionary psychology (e.g., by researchers like Randy Thornhill and Steven Gangestad) show that people rate more symmetrical faces as more attractive.
• This suggests a deep-rooted biological preference, possibly because symmetry is an indicator of developmental stability.
⸻
2. The ‘Golden Ratio’ and Facial Beauty
• The documentary likely references or aligns with research into the Golden Ratio (approximately 1.618:1), which has been observed in many “ideal” facial structures.
• Dr. Stephen Marquardt, a surgeon, developed the “Marquardt Beauty Mask” based on this ratio, claiming it reflects a universally appealing facial structure.
⸻
3. Babies Prefer Symmetry
• One of the most compelling pieces of evidence comes from studies on infants:
• Babies as young as a few months old tend to look longer at symmetrical faces, even if they have no learned cultural preferences.
• Research by Judith Langlois at the University of Texas supports this. Her work found that babies consistently preferred attractive (usually more symmetrical) faces.
⸻
4. Neuroscience and Visual Perception
• Neuroaesthetic studies (e.g., by Semir Zeki) explore how the brain responds to beauty.
• When people view images they find beautiful, activity increases in the medial orbitofrontal cortex—an area linked to reward and pleasure.
• Symmetry, balance, and proportion often stimulate this brain region.
⸻
5. Application in Art and Sculpture
• The documentary ties this preference into art history, explaining why ancient Greek sculptures (e.g., the “Doryphoros” or “Spear Bearer”) reflect idealized, symmetrical forms rather than realistic depictions.
• These artistic choices weren’t arbitrary; they were responses to deep psychological and neurological patterns.
⸻
Summary
Humans are “wired” to prefer symmetrical and proportionate things due to:
• Evolutionary signals of health and fitness
• Innate infant responses to facial features
• Brain reward systems activated by balance and harmony
• Cultural reinforcement of these patterns in art and media
⸻
If you’d like, I can cite specific research studies or academic papers behind each of these points. Would you like those references?
