Reader's real question:

Why this belongs in the catalog:

The error is born at the search box: fast access is booked as knowledge now stored in the head.
Distinct from Illusion of Explanatory Depth (understanding feels complete before any search) and from AI Oracle Fallacy (the model's fluency is the expert).

Bug claim in one sentence:

The bug is the Search Knowledge Illusion, where finishing a lookup makes externally stored explanation feel like knowledge you now contain.

What this bug is not:

Not a claim that using search is lazy. Remembering where to look can be sensible.
Not a claim that a search never teaches. The check is whether you can restate it with the page closed.

Nearby bugs to check:

Nearby bug	Difference
Illusion of Explanatory Depth	A mechanism feels understood until unpacked. This illusion is donated by the lookup.
AI Oracle Fallacy	Trust lands on the model. Here trust lands on you.
Overconfidence Effect	General surplus certainty. This page is the access-specific case.

Concept gate: yes

Source / concept	Year	What it supports	URL / DOI / note
Fisher, Goddu, & Keil. Searching for explanations. JEP: General. Nine experiments.	2015	Searching for explanations raised self-assessed knowledge "in the head," including a brain-image measure.	https://doi.org/10.1037/xge0000070
Sparrow, Liu, & Wegner. Google effects on memory. Science.	2011	Expecting later access shifted memory toward where to find a fact and away from the fact. Neighboring offloading, not the same claim as Fisher.	https://doi.org/10.1126/science.1207745

Do not merge the two findings. Sparrow is what gets stored. Fisher is mistaking access for internal knowledge.

Explained boundary: Access is a skill. The miss is the audit between "I can retrieve this" and "I can explain this with the screen off."

Examples: "I researched it this morning"; gist from the search; "I know the steps" without the steps.

Scenarios: elevator search before a meeting; repair video; forwarded medical paragraph as your own read.

Prevention: close the page and restate; label "looked up."
