Curse of Knowledge
The curse of knowledge is a cognitive bias where an individual, when communicating with others, assumes that others have the background knowledge to understand them. This leads to ineffective communication, as the informed person cannot easily put themselves in the shoes of an uninformed person.
Background
- The "curse of knowledge" is a cognitive bias: once you know something well, you find it almost impossible to imagine not knowing it. This makes you overestimate how clearly you communicate with others.
- The term was popularized by economists Colin Camerer, George Loewenstein, and Martin Weber in a 1989 paper, and later widely applied in psychology, education, and business.
- In practice, the curse explains why experts are often bad teachers, why product designers build confusing interfaces, and why writers produce dense prose — they can't "un-know" what they know.
- A well-known example: if you tap a song's rhythm to someone, you hear the full tune in your head, but the listener hears only taps — you overestimate how obvious the song is.
