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 Saoirse Ronan 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
+2Tailwind
-10+1+2+3
What capability, drive, or early skill is documented in the person rather than their surroundings?
Started acting on Irish TV at 9, Oscar nomination at 13 for Atonement, four Oscar nominations by 25. Extraordinary natural acting talent with early professional trajectory. No formal drama school training.
Where it was dropped
What they were handed
+2Tailwind
-10+1+2+3
What money, family standing, network, or permission was already in place before the work began?
Father Paul Ronan is an actor who trained in New York and appeared in Irish TV/film. Mother Monica also acted as a child. Parents moved from Ireland to Bronx, NYC during recession — father worked construction and as a barman before becoming an actor. Domain knowledge and industry connections despite economic hardship.
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?
Father's acting connections gave early entry into Irish television at 9. Father was on a set where a child was needed for a TV series, providing her first role. Irish TV/film ecosystem. Parents accompanied her to all film sets until age 19, providing stability. NYC birth and Irish upbringing gave dual cultural access. No drama school — learned through practice.
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.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Saoirse Ronan'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 Creators / artists, Saoirse Ronan's starting-advantage total is at the 95th percentile. Separately, their built or converted leverage total is at the 79th 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.

Evidence summary
Ronan's father Paul Ronan was an actor who trained in New York, providing direct domain proximity and industry knowledge.
