Joe Simpson
Milestone (age 25)
Made the first ascent of the previously unclimbed west face of Siula Grande (6,344 m) in the Cordillera Huayhuash of Peru in 1985 at age 25, a major mountaineering achievement that became legendary after his survival story was published in Touching the Void.
Simpson was born in Kuala Lumpur to a Scottish father in the British Army and an Irish mother, and traveled between schools in Britain and various countries. He began rock climbing at age 14 after being introduced to the sport by a teacher at Ampleforth College, and was inspired by Heinrich Harrer's The White Spider. By his mid-twenties he was an experienced alpine climber attempting major first ascents in the Andes.

Joe Simpson'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 Joe Simpson'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, Joe Simpson's starting-advantage total is at the 65th percentile. Separately, their built or converted leverage total is at the 80th percentile. Other T3 profiles average 7.0 / 24 starting advantage and 11.7 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
