Retired professional snooker player; works as a TV commentator and pundit on snooker broadcasts; career-high ranking of world No. 2 (2006/07 season).
Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Ken Doherty against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+2Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Won Irish Under-16 Championship as a young teenager. Won both World Under-21 and World Amateur Championships at 20. Only player to win world under-21, world amateur, and world professional titles. Exceptional snooker talent recognized early.
Where it was dropped
-1Active headwind
What money, family standing, network, or permission was already in place before the work began?
Working-class Catholic family in Ranelagh, Dublin. Father died of a heart attack when Ken was 13. Limited resources. Active disadvantage of working-class background and early paternal loss.
The shape of the track
+1Tailwind
What place, timing, institution, or peer group made the next step available?
Jason's Snooker Hall in Ranelagh provided local access. Irish professional Eugene Hughes provided free accommodation and practice time at Ilford Snooker Centre in London. However, largely self-driven with no elite mentors or institutional support — moved to London with £500 to pursue career.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: High. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Strongest documented signals: Frontier geography, Direct domain exposure, Adversity / constraint catalyst.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Domain proximity, Started serious reps before 20, Prior reps.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Ken Doherty's worth or future potential.
Question four · where did the leverage come from?
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.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
One or more documented starting advantages plausibly enabled this lever.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.
A structural wave is external to the person, even when their position improved access to it.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Ken Doherty's outcome attributable to any origin.
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.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Doherty grew up in Ranelagh, a suburb of Dublin, Ireland. Family financial background is not documented in reviewed sources.
Not documented in reviewed sources.
Doherty grew up in Ranelagh, Dublin, and moved to London to pursue snooker, demonstrating self-driven dedication to the sport.
