Sara Seager'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 Sara Seager'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, Sara Seager's starting-advantage total is at the 86th percentile. Separately, their built or converted leverage total is at the 83th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
Seager grew up in Toronto with a physician father who encouraged her scientific interests. She studied physics at the University of Toronto before completing her Harvard PhD at 26 under Dimitar Sasselov, working on exoplanet atmospheres at the dawn of the exoplanet era. The Harvard astronomy ecosystem and the timing of the exoplanet revolution were key advantages.
