illusion_of_explanatory_depth
The belief that one understands complex systems and mechanisms much better than one actually does. When asked to explain how something works in detail, people discover their understanding is far shallower than they believed. This illusion is particularly strong for causal and mechanical knowledge, as opposed to factual or procedural knowledge.
Most people believe they understand how a toilet works until asked to explain the mechanism step by step. They quickly realize they cannot explain the siphon mechanism, float valve, or refill process, despite having used toilets thousands of times.
A politically engaged person confidently advocates for a specific tax policy at dinner parties, but when a friend asks them to explain exactly how marginal tax brackets are calculated and how they interact with deductions, they quickly trail off, realizing their understanding was more slogan than substance.
A frequent flyer is certain they understand 'basically how planes fly' — something about wings and air pressure. But when their curious child asks why the wing shape causes lift and what Bernoulli's principle actually means, the parent realizes they cannot explain the mechanism at all beyond vague hand gestures.
Binary (yes/no) questions an LLM must answer to identify this aspect:
Can the claimed understanding be articulated in step-by-step detail?
Type: binaryDoes confidence in understanding exceed the ability to explain the mechanism?
Type: binaryWould a detailed explanation reveal significant gaps in knowledge?

Familiarity with outcomes is confused with understanding of mechanisms. We interact with objects and systems at the input-output level and mistake this operational familiarity for causal understanding. The illusion persists because daily life rarely requires deep mechanistic explanations.
Test your understanding by trying to explain something in step-by-step detail before claiming expertise. Seek out and attend to gaps in your explanations rather than glossing over them.
This illusion affects political opinion strength (people moderate positions after attempting to explain policies), consumer product evaluations, technology adoption decisions, and expert overconfidence in complex domains.
