Illusion of Explanatory Depth – when you think you understand until you have to explain
Do you think you understand how a fridge works but struggle to explain what happens inside? That’s Illusion of Explanatory Depth – the tendency to overestimate your knowledge of a topic until you actually have to explain it.
Where it can show up
- Technology – you believe you know how Wi-Fi works but get confused when trying to explain it.
- Economics & Politics – you’re sure you can describe inflation, but beyond a few phrases, your understanding is shallow.
- Medicine – you know vaccines are beneficial but can’t explain how they function.
A practical countermeasure
- Try explaining in simple terms – if you can’t explain it to a 5-year-old, you don’t fully understand it.
- Be ready for questions – check if you can answer follow-ups rather than just repeating memorized statements.
- Develop real understanding – don’t stop at surface-level knowledge; dig deeper into the details.
