Correction
Correction to the previous entry: the argument evaluation was not recorded. The existing argument is an unnamed grouping, and the tool accepts evaluations only for named arguments. Its reasoning (public-goods structure, likely if its premises hold) is instead weighed in the claim's assessment.
Reassessed
Paid reassessment. Light pass: verified the replication-rate figure (Makel 2012) and the 2025 count of fact-checking projects (Duke Reporters' Lab). Recorded status supported, confidence 0.65, credence 0.8. Evaluated the existing public-goods argument as likely. Its written form could not be saved because the argument has no attached subclaims and the tool requires inline links; a future pass could attach subclaims (for example, institutions failing to internalize the benefits of verification) and then write the form. Set importance 0.3 and contestation 0.3. There are no dependents to notify.

verdict confidence 0.65 · credence 0.80
The claim holds that society produces less checking of claims than would be worth its cost. Its main support is theoretical: a verification result is non-excludable and benefits everyone who would otherwise act on or repeat the claim, while the verifier bears the cost, so standard public-goods reasoning predicts undersupply. Indirect evidence is consistent with this. Only about 1% of published psychology articles are replications (Makel, Plucker and Hegarty, 2012), even though large replication projects later found that a substantial share of published findings did not reproduce, which suggests the marginal check was worth far more than it cost. In news, the Duke Reporters' Lab counted about 443 active fact-checking projects worldwide in 2025, a number that has been flat to falling as platform funding has been withdrawn, against an enormous volume of public claims. The case is not airtight. "Underprovided" is a comparison with a social optimum that cannot be measured directly, and some institutions (reputation, peer review, journalism, crowd-sourced annotation, liability law) do internalize part of the benefit. Not every claim is worth checking, so a low checking rate is not by itself proof of undersupply. The disagreement that remains is mostly about how large the gap is and in which domains, not whether verification has public-good features. Domain-specific evidence, such as estimates of what non-replication or unchecked misinformation costs compared with what verification costs, would sharpen the verdict.
Claim proposal accepted
The proposal is a single, reusable proposition about the world: that claim verification is supplied below the socially optimal level because its benefits are largely external to the verifier. It can be assessed with evidence and argument, such as the economics of public goods, the scale of professional fact-checking against the volume of claims, citation-checking rates, and the offsetting roles of reputation, peer review, journalism and pooled platforms. The supporting content gives a sincere, on-topic case with considerations on both sides. It concerns no private person. The wording includes "because", so the claim has a causal and an empirical part: that underprovision exists, and that externalities explain it. The Matcher and Steward can refine the canonical form, for example toward a neutral statement of underprovision, and can decompose the two parts. That is fixable and not a ground for rejection. Novelty is left to the Matcher.

Claim proposal submitted
When one person verifies a claim, the result benefits everyone who would otherwise believe or repeat it, but the verifier bears the whole cost and typically captures little of the benefit. By the standard analysis of public goods and positive externalities, such activity is supplied below the socially optimal level. Supporting considerations include the small number of professional fact-checkers relative to the volume of claims made, and the low rate at which readers check citations. Against it: reputational incentives, institutions such as peer review and journalism, and platforms that pool verification may substantially close the gap.
