What is the difference between compounding and the Lindy effect?

Compounding describes growth that builds on itself over time (an accelerating curve). The Lindy effect describes survival — for non-perishable things, the longer something has lasted, the longer it is likely to last. One is about accumulation; the other about durability.

How do compounding and the Lindy effect work together?

Use the Lindy effect to choose durable things worth investing in — proven skills, lasting institutions, enduring ideas — then let compounding grow them over the long term. Lindy selects the robust substrate; compounding rewards patience in building it.

Why does the Lindy effect favour old things?

Because for ideas, books, and technologies, survival is evidence of robustness. Anything that has lasted a long time has already withstood the forces that kill newer rivals, so its expected remaining life grows with its age — the opposite of how physical, perishable things age.

Compounding vs the Lindy Effect

Both are about time but make different bets. Compounding is about growth — value building on itself, so starting early pays exponentially. The Lindy effect is about survival — what has lasted will likely last longer, so the old is the safer bet. Growth versus durability.

Dimension	Compounding	Lindy Effect
The bet	On growth over time	On survival over time
Key insight	Gains build on prior gains	Age predicts further longevity
What it favours	Starting early; never interrupting	The time-tested over the new
Applies to	Money, skill, reputation, habits	Ideas, books, technologies, institutions
The shape	An accelerating curve	A widening expected lifespan

Two ways time creates advantage

Both models say that time is a force to be respected, but they exploit it differently. Compounding is about *accumulation* — let value build on itself and the curve bends upward. The Lindy effect is about *persistence* — what has already endured tends to keep enduring. One tells you to start the snowball early; the other tells you to trust what has already rolled a long way.

Compounding: growth on growth

Compounding is the engine behind interest earning interest, skill building on skill, and reputation begetting opportunity. Its defining feature is acceleration: the curve looks nearly flat early, then turns steep. This is why patience and an early start matter so much — and why Munger's rule is "never interrupt it unnecessarily." The magic is all in the later years.

The Lindy effect: age as a survival signal

For non-perishable things — ideas, books, technologies, institutions — the Lindy effect says life expectancy increases with current age. A book in print 50 years will likely outlast this year's bestseller; a century-old technology will probably outlive a trendy new one. Endurance is a track record, and a long one is evidence of robustness against the things that kill newer rivals.

How they combine

They pair powerfully for the long term. Use the Lindy effect to *choose what to compound*: invest your compounding effort in time-tested skills, durable institutions, and ideas that have already survived, rather than fragile fads that may vanish before the curve bends. Lindy picks the durable substrate; compounding grows it. Betting on the long-lasting *and* giving it time to compound is how outsized, durable advantage is built.

The verdict

Let Lindy choose and compounding grow. The Lindy effect points you toward what is likely to still be here in decades — proven skills, durable institutions, enduring ideas. Compounding then rewards you for starting early and never interrupting the build. Fragile, trendy bets fail the Lindy test and rarely survive long enough to compound; durable bets, compounded patiently, are where the largest long-run results come from.
