Selected age-relative milestone · age 18
Won two gold medals at the IMO (1987 at 16, 1989 at 18, both perfect scores) and was a two-time Putnam Fellow at Harvard (1990, 1992).
Born in Potomac, Maryland to two statisticians, Ellenberg was a child prodigy who taught himself to read at age two. He scored 800 on the math SAT at 12 and won two IMO gold medals before college.
Born to two statisticians in Potomac, Maryland; showed extraordinary mathematical ability from toddlerhood.
Current position (2025)
John D. MacArthur Professor of Mathematics at University of Wisconsin-Madison; bestselling author.
Where the conditions came from
Three sources, read side by side
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Jordan Ellenberg against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.

What they brought
+3Tailwind
-10+1+2+3
What capability, drive, or early skill is documented in the person rather than their surroundings?
Taught himself to read at age 2. Scored 800 on math SAT at 12. Two IMO gold medals (1987, 1989) with perfect scores. Two-time Putnam Fellow at Harvard. Part of Johns Hopkins Study of Mathematically Precocious Youth. Rare, prodigy-level ability.

What money, family standing, network, or permission was already in place before the work began?
Both parents are statisticians. Mother (Susan Ellenberg) was a biostatistician at University of Pennsylvania and former high school math teacher. House was full of mathematical materials. Strong academic family with direct domain overlap.
The shape of the track

What place, timing, institution, or peer group made the next step available?
Montgomery County math team, University of Maryland honors calculus in 8th grade under Larry Washington. Harvard undergrad, PhD under Barry Mazur. Strong early ecosystem with access to university-level math as a teenager.
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
Perseverance and luck stay visible—not scored.
Documented perseveranceNot documented in the reviewed biographical summaries.
Silence in a biography is not evidence that perseverance was absent.
Luck and unobserved varianceNo discrete luck event is documented in the reviewed biographical summaries.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Describes the starting position, not what the person later made of it.

T3 · Domain-recognized
Notable and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not Jordan Ellenberg's worth or future potential.
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.

Externalmedium confidence
A structural wave is external to the person, even when their position improved access to it.
Frontier geography (1/2)
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Jordan Ellenberg'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 Researchers / independent engineers, Jordan Ellenberg's starting-advantage total is at the 95th percentile. Separately, their built or converted leverage total is at the 71th percentile. Other T3 profiles average 5.3 / 24 starting advantage and 11.0 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
