Weighing the WagerA man leans back at his desk, studying a diagram where a small red triangle sits below a soaring green one. Morning light catches his face as he thinks through the trade-off—what he stands to lose against what he might gain.Tk = (1 − Rn) × step(Up − Dn)
Take the bet when the upside dominates and the worst case is survivable
I take a bet only when its worst case is survivable and its upside dominates its downside. If the worst case could wipe me out, or the upside does not dominate, I don't take it.
The idea
Asymmetric risk: design small losses, unlimited gains Asymmetric risk is a decision framework used by founders and investors: design situations where your downside is limited and clearly survivable, but your upside remains unlimited. Venture capital works this way—most investments fail, but a single winner returns the entire fund. Because outcomes in life are not evenly distributed, a few large wins matter far more than many small losses. The framework has four steps: identify your worst-case outcome, confirm it's survivable, estimate the upside, and take the bet when upside dominates. This reduces fear and hesitation, making action easier. You c
Why this form
Multiplication, because both are needed: a huge upside with a ruinous worst case is not a bet to take, and a survivable worst case with no dominant upside is not worth taking. A step, because the source says to take the bet once the upside dominates.
Symbols
| Tk | Take the bet whether I take the risk 0 = I pass on the bet, 1 = I take it (0-1) |
| Rn | Chance of ruin the chance that a risk I take could wipe me out 0 = the worst case is survivable, 1 = the worst case is ruin (0-1) |
| Up | Upside what I could gain if the bet works, which stays open-ended 0 = no real gain even if it works, 1 = a life-changing payoff (0-1) |
| Dn | Downside what I could lose if the bet fails, which is limited and capped 0 = nothing lost, 1 = a loss as large as the whole upside (0-1) |
Checks
- Have I named the worst-case outcome of this bet?
- Is that worst case survivable?
- Have I estimated the upside?
- Does the upside dominate the downside?
