The Curse of Knowledge Bias is a cognitive bias where someone who knows a lot about a topic struggles to imagine what it’s like not to know it. This makes it hard for them to communicate effectively with someone less informed.

Key Features:

  • Assumes others know what you know: You may explain things in ways that make sense to experts but confuse beginners.
  • Common in teaching, leadership, writing, and UX design: Experts often skip over basics, use jargon, or move too fast.
  • Impacts empathy and communication: It reduces your ability to see from the perspective of a less knowledgeable person.

Example:

A software engineer might say:

“Just SSH into the server and update the YAML config.”

To a non-technical colleague, this is almost meaningless, but the engineer doesn’t realize that because they assume a shared baseline of knowledge.


Avoiding It:

  • Use plain language and define terms.
  • Ask questions to gauge the listener’s understanding.
  • Test your explanations with someone less familiar with the topic.
  • Use analogies or stories that relate to the listener’s world.
