Founder at ParcelBio
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 David Weinberg 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
+3Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Exceptional scientific intellect; PhD in David Bartel's lab at MIT, discovered novel RNAi pathway in budding yeast, 3,498 citations.
Where it was dropped
+1Tailwind
What money, family standing, network, or permission was already in place before the work began?
No evidence of family wealth or connections, but access to MIT graduate education suggests solid educational foundation.
The shape of the track
+3Tailwind
What place, timing, institution, or peer group made the next step available?
Trained in the Bartel Lab at MIT (HHMI), one of the world's top molecular biology labs; later at UCSF and Freenome.
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
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
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, Exceptional peer / cofounder.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Complementary team, Capital safety, Domain proximity.
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.
Notable and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not David Weinberg'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.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.

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.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of David Weinberg'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."
Not documented.
