Documented path
Born in St. Petersburg (Leningrad), Russia, Razborov studied at Moscow State University, completing his PhD in 1987 at age 24. His work on circuit complexity earned the Nevanlinna Prize in 1990.
Born in St. Petersburg (Leningrad), Russia; family background not documented.
Professor of Mathematics and Computer Science at the University of Chicago; Nevanlinna Prize laureate (1990).
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 Alexander Razborov 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?
Completed PhD at Moscow State University at 24. Won Nevanlinna Prize at 27. Strong early mathematical ability in circuit complexity, though no specific prodigy-level competition evidence found.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Born in Belovo, USSR. No evidence of special family background, wealth, or academic connections. Ordinary Soviet family.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
Moscow State University (elite Soviet institution), Steklov Mathematical Institute PhD under Sergei Adian. The Soviet/Moscow mathematical tradition in logic and complexity was strong. Nevanlinna Prize at 27 confirmed exceptional early trajectory.
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, Dedicated mentor / coach.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Scarce skill depth, Domain proximity, Started serious reps before 20.
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 Alexander Razborov'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 Alexander Razborov'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 St. Petersburg (Leningrad), Russia; family background not detailed.
Not documented in reviewed sources.
Razborov completed his PhD at Moscow State University in 1987 at age 24, working on circuit complexity. He won the Nevanlinna Prize in 1990 at age 27.
