Quantifying the Influence of Climate on Human Mind and Culture: Evidence from Visual Art
Shuhei Kitamura

TL;DR
This study quantitatively links climate variations to changes in human culture and mind, using a large dataset of historical paintings to reveal how global temperature shifts influence artistic expression over centuries.
Contribution
It provides the first comprehensive quantitative analysis demonstrating climate's influence on art and human cognition across centuries, using a large-scale dataset and event study methodology.
Findings
Paintings' lightness shows a U-shaped pattern mirroring temperature trends.
High-temperature shocks lead to brighter paintings in subsequent periods.
The effect is stronger in art genres relying on imagination.
Abstract
While connections between climate and the human mind and culture are widely acknowledged, they are not thoroughly quantified. Analyzing 100,000 paintings and data on 2,000 artists from the 13th to 21st centuries, the study reveals that the lightness of the paintings exhibited an interesting U-shaped pattern mirroring global temperature trends. There is a significant association between the two, even after controlling for various factors. Event study analysis using the artist-level data further reveals that high-temperature shocks resulted in brighter paintings in later periods for artists who experienced them compared to the control group. The effect is particularly pronounced in art genres that rely on artists' imaginations, indicating a notable influence on artists' minds. These findings underscore the enduring impact of climate on the human mind and culture throughout history and…
