What Is the Lindy Effect? (Taleb Definition)
The Lindy Effect is the observation that for non-perishable things — ideas, books, technologies, cultural practices, institutions — life expectancy increases with age.
A book in print for 100 years will, on average, remain in print for another 100 years. A book published last month has roughly a month before it's statistically likely to be forgotten. The older the non-perishable thing, the longer it's likely to last.
Named after Lindy's deli in New York (where comedians observed that a comedian's remaining career length correlated with how long they'd already been working), the effect was popularized by Nassim Taleb in Skin in the Game and his broader Incerto series.
The mechanism:
Non-perishable things face continuous exposure to stressors that could destroy them: competing ideas, changing conditions, technological obsolescence, social shifts. What survives has demonstrated robustness to these stressors. The survival is evidence. A 2,000-year-old ethical principle has survived philosophical challenges, political changes, and cultural upheaval across dozens of generations. A principle proposed last year has survived an academic review.
Practical applications:
- Old books, recipes, and practices are more Lindy-compatible than new ones
- Technologies with long track records are more reliable than untested new ones
- Traditional dietary patterns are more robust than newly proposed nutritional regimes
- Folk wisdom that has survived generations carries more evidence than a recent study
The Lindy Effect is compatible with skin in the game: what has survived under real conditions, with real stakes, carries more information than what has been proposed from safety.
