Curse of knowledge: the tapping study in one number
Why the people who know the most are the worst at guessing what others will understand
The result of Elizabeth Newton's 1990 tapping study at Stanford, the best-known demonstration of the curse of knowledge. Tappers expected listeners to name about half the songs they tapped; listeners named 3 of 120. Researchers can use it to explain why discussion guides, tasks and reports written by experts need testing on newcomers. Koji's interview preview makes that test quick to run.
