What the readings rest on

  The date appears only on a people-search or aggregator site

  No public record carries these dates — only data brokers and single aggregators do. That is the broker industry's output rather than something the person or their company published. The research export removed them on that basis: repeating such a date here would put a living person's personal data on the open web on this project's authority.

  What would bring them back — That basis no longer stands here. This project decided on 18 September 2026 that these people should appear rather than be withheld, with the site each date actually came from recorded as a source and shown in full — no word standing in for how good a source is, so a reader judges it from what is cited. What has not happened is the research export carrying them on that footing, and until it does the removal stays in force.

  The research audit found no source behind the date on record

  The research repository's birth-date audit found no source that stands behind the held date. For Stephen Squeri three sources give three different days and none is a filing. For Marvin Ellison and Raj Subramaniam the SEC proxy statements' stated ages, three filings each, rule the held dates out. A reading is a transform of the day, so with nothing behind the day there is nothing to publish. Until 16 October 2026 the export skipped these rows without recording why; it now lists them here.

  What would bring them back — A published document that states the day, entered in full as a source: a filing, an official gazette, a company biography. Bob Swan was in the same position until 16 October 2026, when a Luxembourg gazette entry naming his date was found and recorded, and he is on the site now.

  The year and month are sourced; the day is not

  A near miss is the wrong way to read this. Shifting a birth date by a single day moves the overall score by about 12 points on average, against a real year-to-year swing of 21.9 — so an unsourced day does not make the curve slightly softer, it makes it a different curve. The weak part is the part the model is most sensitive to.

  What would bring them back — A source that states the day, which for a US-listed officer usually means a filing or an official bio.

• 1

  A filing rules out the only date on record

  One source names a day and another rules it out. For Abel Avellan a single aggregator gives 22 February 1971, and the research repository's own audit note records a 2022 SEC 10-K stating his age as 52, which puts the birth a year or two earlier. Nobody here has opened that filing to confirm it. A cycle score is a transform of the date, so publishing one would not be an uncertain result — it would be a result about whichever person the wrong date describes.

  • ASTSAbel Avellan

  What would bring them back — Sources entered for him in full, so the site can judge the date from the evidence rather than from a quality code. Only one source names a day at all, so this is not a case of choosing between two dates; it is a case of one date that a stronger source contradicts.

• 1

  The date was inferred, not found

  The date was worked out from surrounding facts rather than read from a source that states it. An inference can be right, but it cannot be checked, and it is not what the rest of the dataset means by a birth date.

  • SGJonathan Neman

  What would bring them back — A source that states the date, or an SEC filing whose stated age corroborates the inference.

Sources and corrections

The form for submitting a birth-date source or reporting an error is not open yet. When it opens, a person will review every submission before anything changes, and material corrections will be listed publicly.

If you are named on this site and want your birth date taken down, it comes down, and you stay in the roster without one. That does not wait for the form.
