The Lindy Effect

For non-perishable entities, future life expectancy is proportional to current age — the longer something has lasted, the longer it will likely continue.

The Lindy Effect helps you bet on durability by favoring ideas, technologies, and practices that have already stood the test of time.

Core question

How long has this idea, tool, or practice survived — and does that track record predict continued relevance?

Example

When choosing between a programming language with 30 years of production use and one released last year, Lindy thinking weights durability. The older language has survived many hype cycles.

How to apply

  1. 1.Check the age of the tool, idea, or practice you are evaluating.
  2. 2.Prefer time-tested options for critical, hard-to-reverse decisions.
  3. 3.Use newer alternatives for experimental or easily reversible contexts.
  4. 4.Combine Lindy-tested foundations with modern innovations at the edges.

Pitfalls

  • ·Using Lindy to justify sticking with genuinely obsolete technology.
  • ·Applying Lindy to perishable things — it only works for non-perishable ideas, books, technologies.
  • ·Ignoring that some old practices persist due to inertia, not fitness.

Questions

Does the Lindy Effect mean new things are bad?

No. It means new things are unproven. Many will fail; some will become Lindy. The effect is about probabilistic durability, not quality.

Where did the Lindy Effect originate?

From observations about Broadway shows at Lindy's deli. Nassim Taleb formalized it: for non-perishable things, every additional day of survival implies a longer remaining life expectancy.
