How Writing May Shape the Pace of Cultural Evolution
A feature examines whether written language accelerates or restrains cultural change. Russell Gray leads a Max Planck Institute project that applies evolutionary-biology methods to trace how languages shift over time. While some researchers argue writing can codify ideas and narrow thought, Gray cautions that the intuitive answer—that writing slows culture—may not be correct.
Russell Gray, a professor at the Max Planck Institute for Evolutionary Anthropology, leads a project examining how writing shapes language change. His team adapts evolutionary-biology methods, tracing languages through family trees much as biologists trace species.
Arizona State University's Charles Perreault calls one effect "canalization": recording a rule, method or story can narrow how people think about a problem, since the written version may seem definitive. Religious and legal codes show this — centuries-old rules still guide conduct after their original circumstances fade. Ethnomusicologist Patrick Savage's 2017 analysis of 4,000-plus British-American ballads found written melodies changed less than oral ones.
This research could shape how educators, archivists and cultural institutions think about preserving and transmitting knowledge. If writing both stabilizes and constrains ideas, societies may weigh its benefits against the risk of entrenched thinking. Linguists and historians could gain tools for tracing cultural change, while communities relying on oral tradition may find their practices newly visible in the debate. The findings may also inform discussions about how digital archives and AI-mediated text influence which ideas persist.
