lev-os Long Bet Project
Overview
The Long Bet Project, created by the Long Now Foundation in 2002, is a public arena for accountable predictions about the future. It addresses a critical problem: pundits, CEOs, and thought leaders routinely make confident predictions with zero accountability. Media's short attention span lets them escape consequences when wrong.
Long Bets demands predictors put their name, a solid argument, and money down in support of their statement. Winnings go to charity. This mechanism transforms cheap talk into costly signals - if you're wrong, a cause you oppose might benefit. The minimum term is 2 years with no maximum, encouraging thinking across decades or centuries.
The framework operationalizes prediction accountability: your forecast becomes a matter of public record, your reasoning is documented, and resolution is guaranteed by institutional continuity. Warren Buffett's famous 10-year bet against hedge funds (won in 2017) demonstrated the model's power to settle debates definitively.
When to Use
- Making long-term predictions you want held accountable
- Settling debates that won't resolve for years or decades
- Forcing rigorous thinking about future outcomes
- Creating skin in the game for forecasts
- Building institutional memory around predictions
- Testing expertise claims publicly
- Funding charities through competitive prediction
- Challenging overconfident forecasters to back their words
The Process
Step 1: Formulate a Clear, Falsifiable Prediction
State exactly what will happen by when. Binary outcomes only - no hedging.
Poor prediction: "AI will change everything by 2030" Strong prediction: "By December 31, 2030, a commercially available AI system will have won a Grammy for Best New Artist"
Step 2: Build Your Argument
Document WHY you believe this outcome. Include:
- Causal mechanism (what forces make this outcome likely)
- Evidence supporting your position
- Acknowledgment of key uncertainties
- Why the timeline is appropriate
Example argument: "Foundation models demonstrate emergent musical composition. Grammy's 'Best New Artist' eligibility requires human performance, but AI-generated personas with human performers already chart. Commercial incentives push labels toward AI collaboration. Timeline based on 10-year cycles in music industry disruption."
Step 3: Set Meaningful Stakes
Minimum $200 per side, no maximum. Consider:
- Amount large enough to create genuine accountability
- Amount you can afford to lose entirely
- Charity you'd want to fund if you win
- Charity you'd prefer NOT fund (opponent's choice)
Stakes design: Higher stakes = stronger signal of conviction. Buffett bet $1M. Match stakes to confidence level.
Step 4: Publish and Invite Challenge
Make your prediction public. Either:
- Post on longbets.org ($50 publication fee)
- Announce publicly with clear terms and escrow mechanism
Critical: True names required. Anonymous predictions don't create accountability.
Step 5: Wait and Let the Future Adjudicate
Resist the urge to hedge or revise. The prediction stands as written.
Resolution: Mutual agreement between parties if both alive, otherwise Long Now Foundation adjudicates. Public announcement and charitable disbursement.
Step 6: Analyze the Outcome (Win or Lose)
Win: Document what you got right and why your reasoning held. Lose: Conduct honest post-mortem - where did your model break?
Key insight: The learning value exists regardless of outcome. The process of rigorous prediction improves forecasting ability over time.
Example Application
Situation: Tech industry debate about cryptocurrency future (2018).
Application:
- Prediction: "By December 31, 2028, at least one sovereign nation will use Bitcoin as its primary legal tender for all domestic transactions"
- Argument: El Salvador adoption trend, hyperinflation in emerging markets, Lightning Network scalability, generational shift in money perception
- Stakes: $5,000 per side
- Charities: Winner's choice - Electronic Frontier Foundation; Opponent's choice - Institute for Humane Studies
- Publication: Posted on longbets.org with full reasoning
Outcome tracking: El Salvador adopted BTC as legal tender in 2021, but "primary" for "all domestic transactions" remains unmet. Prediction continues.
Scoring Rubric
- Practitioner Weight: 8/10 - Real-money stakes from notable figures (Buffett, Bezos donors)
- Clarity/Executability: 9/10 - Extremely clear process with institutional support
- ROI: 7/10 - Indirect benefits through improved forecasting discipline
- Novelty: 8/10 - Unique mechanism combining prediction markets with charity
- Cross-domain: 8/10 - Applicable to any falsifiable future claim
Total: 40/50
Anti-Patterns
- Making vague predictions that can't be definitively resolved
- Setting stakes too low to create real accountability
- Using pseudonyms or anonymous accounts (defeats accountability)
- Refusing to publish reasoning (hides from scrutiny)
- Revising predictions after initial publication
- Betting on unfalsifiable outcomes ("AI will be important")
- Ignoring the post-mortem learning opportunity
- Only making predictions you're highly confident about (no learning)
