John Barnes's leverage provenance

Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of John Barnes's outcome attributable to any origin.

Luck is not a leftover score.

Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.

Within Athletes, John Barnes's starting-advantage total is at the 38th percentile. Separately, their built or converted leverage total is at the 12th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary

Barnes signed for Watford at 17 in 1981 after being spotted playing parks football in London, a material and independently verifiable milestone. He came from a military family that provided moderate stability when his father was posted to London as a military attaché. He was recommended to Watford by former Arsenal manager Bertie Mee and developed under coach Tom Walley. His natural speed and skill were evident from youth football. He faced racial barriers as a black player in 1980s English football, which shaped his career. No significant family football domain or financial platform advantages are documented.
