What This Is
Legis Ledger is knowledge infrastructure that enables institutions to publish expert opinions with:
- Quantified confidence (Bayesian probabilities, not binary true/false)
- Transparent provenance (who submitted, potential biases, verification paths)
- Real-world validation (track outcomes, update confidence)
- Structured disagreement (preserve pluralism while enabling convergence)
Like Madison's Constitution provides a framework for political disagreement, this infrastructure provides a framework for epistemic disagreement.
Why This Exists
The Problem:
Wikipedia enables cooperation through consensus, which works for settled facts ("Paris is the capital of France") but breaks down for:
- Contested scientific claims ("Does creatine increase muscle mass?")
- Situational judgments ("Is high-dose Omega-3 effective for all patients?")
The existing consensus model cannot accommodate "high confidence for group A, low confidence for group B." This leads to: 1) Fact wars, or 2) Retreat to consensus, which strips out essential nuance.
The Solution: Epistemic Humility Infrastructure
We need infrastructure that tracks **epistemic uncertainty** alongside the claim. A single abstract should be able to convey the probability distribution of expert confidence based on transparent evidence, without requiring consensus.
Status
Epistemic Status: Early-stage prototype (0.65 confidence we can handle contested domains)
Current Confidence in Architecture:
- Can handle legal domain: 0.85
- Can handle scientific domain: 0.90
- Can handle climate change: 0.75 (testing needed)
- Can handle UBI: 0.65 (most uncertain)
