The curse of knowledge
The curse of knowledge is the difficulty experts have imagining what it’s like not to know what they know. Once you understand something you can’t easily un-understand it — so you overestimate how obvious it is to everyone else.
Why does the curse of knowledge happen?
Your own knowledge is so accessible it feels like common sense, and you can’t fully simulate a mind without it. So you skip steps, use jargon, and assume shared context the listener doesn’t have.
Deep expertise and the ability to teach are nearly opposite skills.
What does the curse of knowledge look like in real life?
- The "tappers and listeners" study: tappers of a tune were sure listeners would recognise it about half the time; the real rate was ~2.5%.
- Experts writing documentation that’s impenetrable to beginners.
- A teacher baffled that students don’t "just get" the obvious.
How do you counter the curse of knowledge?
- Test explanations on an actual novice, not in your head.
- Define jargon and spell out the steps you’re tempted to skip.
- Assume less shared context than feels natural — you almost always overestimate it.
The deeper point
It’s why deep expertise and the ability to teach are nearly opposite skills. The better you know something, the harder it becomes to remember not knowing it — which is exactly what a learner needs you to do.
Frequently asked
- What is the curse of knowledge?
- The difficulty of imagining not knowing something you know — leading experts to overestimate how obvious their knowledge is and to communicate over people’s heads.
- What is the tappers and listeners study?
- Participants tapping out a well-known tune predicted listeners would identify it about half the time; only ~2.5% actually did — a vivid demonstration of the curse of knowledge.
- How do you overcome the curse of knowledge?
- Test your explanations on real beginners, define jargon, spell out skipped steps, and assume less shared context than feels natural.
