Only 40% of AI-cited statistics trace back to a study

Comments on “Only 40% of AI-cited statistics trace back to a study”

3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

A Trakkr Research study traced 1,285 statistics cited by five AI assistants and found only 40% led back to a study that said the same thing, with 40% stopping at sources that couldn't be checked and 11% at no study at all.

Read the original at trakkr.ai. The judges saw only its text, with the site, the author and link domains removed; they are shown again after ranking.

Why it ranked

No. 44 of 127 with a score of 0.65. The panel rated it highest on substantiated (0.84) and new information (0.80), lowest on technical depth (0.47). The judges disagreed most on technical depth (spread 0.41), so the story is marked contested. Placed No. 44, No. 34 by score alone: the twelfth AI & machine learning story of the day (−0.080). The placement terms move stories; they are not part of the score.

AI judgeJudge 3gpt-5.6-luna
Original, method-driven measurement of citation provenance across major AI assistants, with actionable implications for verification and publishing. Strongly relevant to AI and research, though reproducibility details and underlying data are limited.

Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.
