The curse of knowledge is a cognitive bias that occurs when an individual, communicating with other individuals, unknowingly assumes that the others have the background to understand.[1] For example, in a classroom setting, teachers have difficulty teaching novices because they cannot put themselves in the position of the student. A brilliant professor might no longer remember the difficulties that a young student encounters when learning a new subject. This curse of knowledge also explains the danger behind thinking about student learning based on what appears best to faculty members, as opposed to what has been verified with students
A 1990 experiment by a Stanford graduate student, Elizabeth Newton, illustrated the curse of knowledge in the results of a simple task. A group of subjects were asked to "tap" out well known songs with their fingers, while another group tried to name the melodies. When the "tappers" were asked to predict how many of the "tapped" songs would be recognized by listeners, they would always overestimate. The curse of knowledge is demonstrated here as the "tappers" are so familiar with what they were tapping that they assumed listeners would easily recognize the tune.
