Documented path

Duncan Haldane

Researchers / independent engineers · Science/Research · milestone at age 25 ·Extreme public outlier
Selected age-relative milestone · age 25
Completed PhD in physics at Cambridge University at age 25 in 1976, under Philip Anderson (Nobel laureate), working on condensed matter theory.

Born in London, England, Haldane earned his BA from Cambridge in 1973 and his PhD in 1976 at age 25 under Philip Anderson. He later made foundational contributions to topological phases of matter, earning the Nobel Prize in Physics in 2016.

Starting point

Born in London, England; family background not extensively documented.

Current position (2025)

Professor of Physics at Princeton University; Nobel laureate in Physics (2016).

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 Duncan Haldane 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

What they brought

+1Tailwind

What capability, drive, or early skill is documented in the person rather than their surroundings?

Attended St Paul's School London (elite) and Christ's College Cambridge. No specific prodigy indicators found. Solid academic trajectory through elite British educational system.

Where it was dropped

What they were handed

+2Tailwind

What money, family standing, network, or permission was already in place before the work began?

Father was a psychiatrist in the NHS, from Scotland. Mother was a Carinthian Slovene medical student from Austria who couldn't complete her studies in Britain. Medical family that greatly valued science and education. Multicultural heritage.

The shape of the track

What surrounded them

+3Tailwind

What place, timing, institution, or peer group made the next step available?

St Paul's School London (elite private school), Christ's College Cambridge, PhD under Philip Anderson (Nobel laureate) at Cambridge. The St Paul's-to-Cambridge-to-Anderson pipeline was exceptional for condensed matter physics.

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.

Question four · where did the leverage come from?

Duncan Haldane'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 Duncan Haldane'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, Duncan Haldane's starting-advantage total is at the 41th percentile. Separately, their built or converted leverage total is at the 83th percentile. Other T1 profiles average 8.7 / 24 starting advantage and 13.6 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
