Protect a floor. Leave room for upside.
Taleb's barbell separates strongly protected resources from exposure with substantial upside. Its protection depends on keeping the safe side safe and the risky loss bounded.
Inside this model
Terminal units = 100 − allocation + allocation × (1 + return/100). The comparison allocates all 100 units to the same risky project. The reserve earns zero, the project cannot lose more than its stake, and there is no borrowing.
Out in the world
A practical use
A team might protect its operating budget while funding a small experimental product, rather than putting essential operations at risk.
A useful lens. Not a universal law.
- This is a one-period resource allocation model, not a portfolio recommendation. Inflation, counterparty failure, costs and leverage can invalidate the protected-floor assumption.
