Flaws in Wikipedia editors' and readers' self-awareness about their own knowledge and judgment while using the platform. These biases distort how contributors assess their expertise, gauge the reliability of their edits, and monitor their comprehension of policies. Key examples include the Wikipedia Illusion of Explanatory Depth (believing you understand a topic fully after editing its article, when you've only mastered its presentation), and Procedural Overconfidence (thinking that strictly following citation and NPOV rules guarantees you've produced a "true" article, mistaking process-compliance for substantive understanding). These biases turn the wiki-editing experience into a metacognitive trap, where the act of curation is mistaken for mastery.
Metacognitive Biases of Wiki Example: A Wikipedia editor spends weeks polishing the article on "Quantum Entanglement," meticulously sourcing every claim. They develop a strong Metacognitive Bias of Wiki: the "feeling of knowing." They now believe they deeply understand quantum physics, confusing their hard-won skill in encyclopedic summarization with actual expertise in theoretical physics, and may start arguing authoritatively on physics forums, leading to embarrassing corrections.
