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 Lucy Guo 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
+2Tailwind
-10+1+2+3
What capability, drive, or early skill is documented in the person rather than their surroundings?
Taught herself to code in elementary school to cheat at Neopets. Making money via PayPal by second grade. Built bots for online games, sold Pokémon cards, created websites with Google AdSense. Above-average early technical and entrepreneurial ability.
Where it was dropped
What they were handed
+1Tailwind
-10+1+2+3
What money, family standing, network, or permission was already in place before the work began?
Both parents were Chinese immigrant electrical engineers who were laid off early in her life, leading to a very frugal upbringing. Grew up in Fremont/Pleasanton, California. Middle-class immigrant family with technical exposure but financial constraint.
The shape of the track
What surrounded them
+2Tailwind
-10+1+2+3
What place, timing, institution, or peer group made the next step available?
Carnegie Mellon University (dropped out for Thiel Fellowship). Internships at Facebook, Snapchat (first female designer, helped build Snap Maps), and Quora where she met Alexandr Wang. Y Combinator. Silicon Valley ecosystem from a young age. Thiel Fellowship provided runway.
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.
Encounter luckDropped out of Carnegie Mellon University after being selected for the Thiel Fellowship, a $100,000 grant for young entrepreneurs.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.

T1 · Global icon
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Lucy Guo'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.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Lucy Guo'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 Founders / operators, Lucy Guo's starting-advantage total is at the 94th percentile. Separately, their built or converted leverage total is at the 99th 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.
