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 Jaedong (Lee Jae-dong) 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
+3Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Arcade fanatic from third grade, parents bought him a computer in fourth grade where he discovered StarCraft. Won Rookie of the Year in 2006 at 16 and went on to win 5 OSL/MSL premier titles. Recorded the highest win rate (68.4%) in Brood War history. Prodigy-level ability in the most competitive esports ecosystem of its era.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Born in Ulsan, South Korea. Parents initially opposed his gaming career. Middle-class family with no esports connections. Parents bought him a computer in fourth grade, which was the key access point. No documented family wealth or industry advantages.
The shape of the track
+3Tailwind
What place, timing, institution, or peer group made the next step available?
Entered the Korean professional Brood War pipeline at the peak of its competitiveness. Joined Hwaseung OZ, a KeSPA-registered team with professional infrastructure including team houses, coaches, and televised matches. The Korean esports infrastructure was once-in-a-generation, with televised leagues and professional team systems.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. 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
Silence in a biography is not evidence that perseverance was absent.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Strongest documented signals: Elite institution pipeline, Frontier geography, Direct domain exposure.
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.
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Jaedong (Lee Jae-dong)'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.
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 Jaedong (Lee Jae-dong)'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."
Born in Ulsan, South Korea; parents bought him a computer in fourth grade, which introduced him to StarCraft via his brother's friend. Was an arcade fanatic from third grade. Specific parental occupation and financial details not documented.
No parental gaming or tech domain expertise documented. Parents' purchase of a computer was a pivotal enabler but not necessarily a domain advantage.
Jaedong grew up in Ulsan, South Korea, during the peak of the Korean Brood War esports ecosystem. His parents' purchase of a computer in fourth grade introduced him to StarCraft, and his arcade background from third grade built his gaming foundation. He joined the Korean professional gaming pipeline at 16, debuting with Hwaseung OZ in 2006 and winning Rookie of the Year. The Korean esports infrastructure — team houses, televised leagues, and KeSPA ranking system — provided an elite performance pipeline. His prodigy-level Zerg play, particularly his mutalisk micro and 81% ZvZ win rate, set him apart. He won five premier individual league titles by age 26.
