Evidence coverage · live from the published dataset
Complete enough to inspect.
Not complete enough to predict.
Every published path has a milestone, narrative context, present-day position, and trajectory. That structural completeness is useful. It is not the same as independent verification, representative sampling, or causal evidence.

Four different claims
Coverage is a ladder—not one percentage.
A filled field is not a verified fact. A listed source is not an independent audit. The product keeps those levels separate.
Two source domains
2,457 profiles link evidence across at least two domains.
Indexable evidence
Two sources, non-low leverage confidence, a milestone, and a trajectory.
Independently audited
This gate remains pending. The product does not imply otherwise.
Annotation confidence
The weaker layer is documented starting advantage.
Biographies reliably celebrate output. They are much less consistent about money, introductions, family logistics, private coaching, permission, and social capital.
Starting-advantage evidence
What access or conditions were documented near the beginning?
Built-leverage evidence
What multiplying capacity was documented later in the path?
Sample composition
A selected atlas—not a miniature population.
Every person already cleared an early-breakthrough threshold. These shares describe this atlas only; they do not estimate how common success is.
Cohort share
Observed career tier
Tiers summarize documented career recognition. They do not measure human worth, potential, or only the selected early milestone.
The denominator that is missing
This project cannot count every promising path that disappeared.
There is no matched group of ordinary attempts, near-misses, or people with similar backgrounds who never reached a documented milestone. Therefore this dataset cannot estimate success probabilities, causal effects, or “how many failed for every Bill Gates.”
What would earn an audited v1.0
The remaining work is external validation—not more decoration.
- 01Double-code a stratified sample.
Use an independent rater across every cohort-tier cell and publish disagreement.
- 02Audit sensitive and milestone claims.
Require stronger sources, retrieval dates, and exact evidence spans.
- 03Observe first-time readers.
Test comprehension and the intended emotional arc without coaching.
- 04Add a matched comparison study.
Only then could population odds or counterfactual claims be investigated.
