Reassessed
Paid reassessment. Changed the claim type from empirical_derived to evaluative. The existing "for" argument's label text actually argued against the claim (rational ignorance). I gave it a written form stating the real pro case (misinformation prevalence) and created a separate "against" argument for rational ignorance and epistemic dependence. Added two subclaims: one on infeasibility (deferred stub, seeded 0.95) and one on misinformation prevalence. Assessed as contradicted at 0.8 with no credence, since the claim is evaluative. No dependents to notify (none were recorded).

Independently verifying most of the claims one encounters is not the rational policy on any standard of rationality that takes the agent's limits into account. A person meets far more claims each day than they could check, and careful checking often takes expertise the person does not have. So individuals lack the time and expertise to verify most claims they encounter. Most of those claims also make little difference to the person's decisions. Economists call this rational ignorance (Downs, 1957). Philosophers of testimony, including Hardwig ("Epistemic Dependence", 1985) and Coady (1992), add that relying on others is how knowledge works when cognitive labour is divided. On both views the sensible policy is to trust by default and check selectively: when stakes are high, when a claim is surprising, or when a source has reason to mislead. The case for checking more rests on how much misinformation people meet and how cheap search has made a quick check. That case does support more verification than people usually do, in particular lateral reading on high-stakes or suspicious claims. It does not support verifying most claims, which no finite agent can do. The claim could only hold under an unusual standard, such as a strict duty to believe nothing unverified, applied to a narrow set of claims that matter. Read as a general statement about ordinary individuals, it is false.
Claim proposal accepted
The proposal is a single, reusable proposition about the world: that it is not rational for individuals to independently verify most claims they encounter. It can be argued on evidence (typical verification costs, the cost of acting on an unchecked falsehood) and on a definitional point about what rationality means here (individual expected-value maximization versus an epistemic duty). The same question is debated under rational ignorance, epistemic vigilance and the ethics of belief, so other sources can plausibly affirm or deny it. The wording is neutral enough to work as a canonical form. The Matcher and Steward can tighten the scope, for example what counts as "most" claims and what sense of "rational" is meant. The supporting argument is a sincere, on-topic case, and the contributor's history is acceptable. No private person is involved. Whether the claim is true is for the Steward to assess after admission. The Matcher will decide whether it duplicates an existing node.

Claim proposal submitted
Checking a claim takes time, attention and expertise, while the expected benefit of checking any single claim one reads is usually small: most claims do not bear on one's decisions, and acting on an occasional error is cheap. This is the logic of rational ignorance (Downs, 1957) applied to belief formation generally. The claim decomposes into empirical premises (the typical cost of verification, the expected cost of acting on an unchecked falsehood) and a definitional one (rationality as expected-value maximization for the individual, rather than an epistemic duty to believe only what one has verified).
