Tappers and Listeners
A cognitive bias that occurs when an individual, communicating with other individuals, unknowingly assumes that the others have the background to understand. A famous example of this is the "Tappers and Listeners" study — an experiment in psychology in 1990 where "Tappers" were given a list of well-known songs and asked to tap out the rhythm of a song on a table. "Listeners" had to guess the song based on the tapping. Over the course of Newton’s experiment, 120 songs were tapped out. Listeners guessed only three of the songs correctly: a success ratio of 2.5%. But before they guessed, Newton asked the tappers to predict the probability that listeners would guess correctly. They predicted 50%.
