Metacognitive Myopia

INTRODUCTION
English translation pending.
CORE DEFINITION
A concept from cognitive psychology describing attention to first-order information at the expense of second-order information about how that information was produced. The core proposition is that people evaluate the message while neglecting its provenance, so a vivid claim from a tiny biased sample can be treated as evidence. The key qualification is that the failure is attentional rather than motivational, occurring even in people who know that source quality matters.
SCAFFOLDING EFFECT
Reduce cognitive load
- Provenance prompt: ask how the number was produced before evaluating what it says. - Sample audit: check the size and representativeness of the underlying sample. - Method check: ask whether the collection process could have biased the result.
Anchor fast decisions
Content is processed automatically and cheaply, while provenance requires deliberate retrieval of context that is not present in the message itself. Vividness and fluency therefore dominate judgment, and the sample is treated as if it represented the population. Because the omission is attentional, knowing the principle is not enough; a routine check must be triggered by the format of the claim.
