New versions of this research opportunity and changes to the claims it rests on. 2026-10-21T00:00:00Z SocioLens urn:uuid:944f542b-fb0c-5f02-8a78-8fc784e7dc9a Research opportunity revised to v3: RO-LD07-01 — Do pinned model snapshots keep social-science conclusions stable over time? 2026-10-21T00:00:00Z The note on the nearest work by Chen, Zaharia and Zou no longer says its Harvard Data Science Review issue details are unconfirmed: the DOI's Crossref record (checked 21 October 2026) gives Harvard Data Science Review volume 6, issue 2 (2024), as the References already did. The question, design, literature check and verdict are unchanged. urn:uuid:acf93e2f-ab37-55e8-bb46-3546d850e630 Research opportunity revised to v2: RO-LD07-01 — Do pinned model snapshots keep social-science conclusions stable over time? 2026-10-13T00:00:00Z Literature check added: a second, deeper search for existing work, with its queries, new nearest work and limits. The question and verdict stand. urn:uuid:88909a3f-ab1a-5549-90c5-b3b2a14c3dd3 New research opportunity: RO-LD07-01 — Do pinned model snapshots keep social-science conclusions stable over time? 2026-10-12T00:00:00Z On a fixed battery of published social-science annotation tasks, how often does a substantive conclusion (sign, significance, interval coverage) change between repeated queries of a pinned model snapshot, a moving model alias over 6–12 months, and successive open-weight releases, and can design-based correction absorb those changes?
