Synthetic Polls Fall Short

Updated: 2026.10.24 21D ago 2 sources
Large language models can imitate some public‑opinion answers but produce systematic, model‑dependent errors on many questions; accuracy varies by question type, prompting, and model version. Pew’s replicated tests (GPT‑5.1 and Claude Opus 4.6) show some questions are well matched while others diverge by multiple percentage points, so synthetic samples cannot yet replace human interviewers for reliable polling. — If media, campaigns, or researchers accept synthetic survey outputs uncritically, they risk amplifying biased or unstable measurements that could misinform policy debates, election coverage, and scholarly work.
