Factual Their own work or organisation

ACX meetups in Rockville, Northampton, Eindhoven, Great Barrington, Cairo, Portland and Sofia have had changes announced as of October 2026.

Unresolvable The public record could not settle it.

Factual: Statements about the present or the past, checked against the record: did they hold up?

What would count as true or false

Judge as of 2026-10-19. True: an ACX post (Open Thread or meetup post) on or around that date announces changes (new time, venue, date, organiser, cancellation or similar) for ACX meetups in all seven places: Rockville, Northampton, Eindhoven, Great Barrington, Cairo, Portland and Sofia. Mostly true: changes are announced for six of the seven, or for all seven but one place is named slightly differently (e.g. a nearby town). Mixed: changes are announced for about half (3–4) of the listed places. Mostly false: changes are announced for only one or two, or the announcement exists but concerns a different set of places. False: no such meetup-change announcement exists, or the record shows none of these places had changes announced.

Set before the research began.

Reasoning

The 'Meetups Everywhere 2026: Times & Places' post (E1, E3, E4, E5) lists meetup details for Sofia, Great Barrington and Northampton, but none of these quotes says that a change was announced. No evidence mentions Rockville, Eindhoven, Cairo or Portland. Open Thread 457 (E2) covers a different set of new meetups (Berkeley, Beijing, Kansas City). The Northampton date on LessWrong (E6) differs from the ACX listing (E4), but no source calls this a change. None of the evidence includes the Open Thread around 19 October that would contain the announcement, so the claim cannot be confirmed or refuted.
