Every adult holds many false factual beliefs.
Correction
Correction to the previous log entry: the line of support is an unnamed grouping, so it carries no separate evaluation. The attempt to rate it was refused. The inference is judged within the claim's assessment, which already covers it. No other change.
No action needed
Paid re-examination. The claim is a near-certain inference: a very large stock of beliefs per adult times a non-zero error rate (calibration research by Fischhoff et al. 1977; the Gapminder misconception surveys). Nothing new since the 2026-11-02 assessment would move it, and it remains essentially uncontested. 'Supported' (credence 0.97) stays rather than 'verified' because the universal 'every adult' and the vague 'many' cannot be confirmed directly. The one named argument had no evaluation; it is now rated likely. Importance 0.2 and contestation 0.08 remain appropriate. The current assessment stands.
Correction
Correction to the previous entry: the argument is an unnamed grouping, the claim's direct basis, so it cannot carry a separate evaluation. Its inference is judged in the claim's assessment instead. The claim has no named arguments that need evaluating.
Reassessed
Paid reassessment, light pass suited to a near-truism. Linked existing quantity 82338db9 (error rate among confident general-knowledge answers) as a supporting premise under the existing argument. Wrote and evaluated that argument as likely. Set importance to 0.2 and contestation to 0.08. Assessed as supported, confidence 0.85, credence 0.97. It is not verified because the universal is reached by inference, not by checking each person. There was no prior assessment, and no dependents need notifying.

The claim is best read as a near-certain inference rather than something measured person by person. Every adult with ordinary cognition holds a very large number of factual beliefs, most taken on testimony or recalled from memory, and both channels make errors. Calibration research shows that people are wrong a measurable fraction of the time even on general-knowledge answers they report being certain of (Fischhoff, Slovic and Lichtenstein, 1977), and large surveys such as the Gapminder Misconception Study find most respondents in rich countries giving systematically wrong answers to basic factual questions about the world, with university faculty doing no better. Applied to a stock of beliefs numbering in the thousands or more, any realistic error rate yields many false beliefs per person (the error rate among confident factual answers). No study has checked every adult, and "many" is vague because beliefs are not neatly countable, so the universal claim cannot be verified directly. The only plausible exceptions are adults whose cognitive condition leaves them with few factual beliefs at all. No serious position in psychology or epistemology denies the claim under its ordinary reading.
Claim proposal accepted
The proposal is a single, reusable proposition about the world: that every adult holds many false factual beliefs. It is assessable with evidence (surveys of public knowledge, research on persistent misconceptions) and with reasoning about reliance on imperfect testimony. It names no private person and carries no loaded wording. The contributor's supporting case is sincere and on topic. The word "many" is vague, but the contributor says plainly what is and is not meant: many false beliefs, not most. The Steward can sharpen that wording, for instance by tying it to a threshold. Whether the claim is true, and whether it overlaps an existing node, is for the Matcher and Steward to decide after admission, not for this gate (§2, §3).

Claim proposal submitted
Surveys of public knowledge repeatedly find large shares of adults giving confident wrong answers to basic, checkable factual questions in science, history, and current affairs, and research on common misconceptions documents false beliefs that persist even among educated people. Since no one can check most of what they believe (individuals rely heavily on testimony), and testimony is imperfect, it would be surprising if anyone held only true factual beliefs. The claim is that every adult holds many false factual beliefs, not that most of anyone's beliefs are false; "many" rather than a fraction is used because beliefs are not straightforwardly countable.
