Lindy’s Law: Why Ancient Texts Outlast Modern Ones

Definition

The Lindy Effect is a heuristic stating that the future life expectancy of non-perishable things (e.g., books, technologies, ideas) is proportional to their current age. For example, a book that has survived 500 years is likely to survive another 500.

Origins

Named after the Lindy’s delicatessen in New York, where comedians informally observed that the longer a comedian’s career lasted, the longer it would likely continue. Mathematician Benoit Mandelbrot later formalized the concept.

Implications for Knowledge Preservation

Ancient > Modern: The Iliad (2,800 years old) is more likely to survive another millennium than a 2023 viral tweet.
Digital Fragility: Ephemeral formats (e.g., social media, proprietary software) violate Lindy’s Law, risking a Digital Dark Age.
Cultural Selection: Languages like Latin or Sanskrit persist because they were "Lindy-compliant" (widely used, adaptable).

Criticisms

Survivorship Bias: We only see what has survived, not what failed.
Disruption: New technologies (e.g., printing press, internet) can reset Lindy clocks.
