Expertise hides the missing steps
The curse of knowledge explains why privileged information can contaminate estimates of what a less-informed person can perceive, infer, or understand
Premise
Expertise creates a communication problem precisely because useful knowledge becomes cognitively hard to remove. Once an answer, method, outcome, or technical vocabulary is familiar, the earlier state of not knowing is difficult to reconstruct. Missing steps disappear into compression, and information that now feels obvious begins to look as though it should have been obvious to everyone.
For executives, this changes the standard for clarity. Confidence that a message “makes sense” is weak evidence when the sender has lived with the issue for months. The relevant test is whether the organization can reconstruct the recipient’s actual information state: prerequisites, vocabulary, permissions, prior events, and inferential bridges available before the message arrives.

Effects, Biases & Phenomena
Identifies a bounded pattern in judgment, behavior or communication and the conditions under which it appears. Naming the pattern makes a recurring difficulty recognizable; it does not make the pattern inevitable or supply a complete explanation.
