When this applies
when deciding whether to build or invest during what looks like the worst possible environment
The takeaway
Because only optimists create and capture compounding upside, choosing optimism is a rational strategy, not just a feel-good disposition.
Why it works
Optimists are the ones who actually attempt and build things; pessimists by definition don't act, so all forward progress and outsized returns are captured only by those willing to bet on improvement.
One level up
In any domain driven by compounding returns, the expected value of acting outweighs the comfort of correctly predicting decline.
Where it stops holding
This stops working when the underlying growth engine (e.g., technology, market, compounding mechanism) is genuinely absent, not just temporarily depressed.
Detail
rule: When conditions look hopeless, bet on optimism because optimists are structurally the only ones who can capture the upside of recovery/growth.
threshold: Applies when there is still some latent capability or market waiting to activate (e.g., post-war Japan still had people and demand, just no technology or capital).
rationale: If you're not an optimist, it's the optimists who drive the world forward; investing in optimism is the only way to get outsized returns.
In their words
So the lesson that we take away from this is: even if things are at their bleakest, it's rational to be an optimist.
