The Lindy Effect: Time's Ultimate Stress Test

The longer something has survived, the longer you can expect it to stick around.

Explanation

The Lindy effect is a mental model for non-biological things like ideas, books, technologies, and cultures. Unlike humans, who become more fragile with age, these things become more robust the older they get. If a book has been read for 500 years, like Machiavelli's The Prince, you can expect it to be read for at least another 500 years. If a new app has been popular for two weeks, its expected future lifespan is likely just another two weeks. The Lindy effect reminds us that time is the ultimate filter for quality. In a world full of fleeting trends and breaking news, the model helps us focus on what truly has lasting value. Want to read something guaranteed to offer insight?
