Synthetic research tools that publish their error rate
A synthetic research tool that publishes its error rate posts a number, a denominator, named polls, and a file you can download. Lewsearch publishes 7.47% mean absolute error on 404 ex-electoral questions of a 460-question benchmark versus Pew, Gallup, UT/Texas Politics Project, and PPIC. The respondents are living agents with persistent memory, not one-shot personas.
What a published error rate has to include
A percent with no denominator is a slogan. Lewsearch posts 7.47% MAE on 404 ex-electoral questions of a 460-question pool. Do not write that as "7.47% across 460questions." The 56 electoral-margin items are scored separately because they are harder.
The public file
lewis-benchmark-per-question.csv has 443 scored rows. lewis-benchmark-summary.json is the same headline numbers in JSON. Method write-up: methodology.
| Claim | What to ask |
|---|---|
| Pooled MAE vs named polls | Which questions, which polls, where is the CSV? |
| Agreement percent | Agreement of what with what? Is there a public instrument file? |
| Spearman / thematic parity | Different unit. Do not convert it into MAE. |
