The phenomenon you are referring to is known as the "curse of knowledge". It occurs when someone who is knowledgeable about a particular subject or concept, such as a teacher or expert, has difficulty understanding why someone who is less knowledgeable does not understand it. This is because the knowledgeable person has already internalized the information and may not be able to "unlearn" it in order to see it from the perspective of someone who is new to the subject. The term "curse of knowledge" was coined by economists Colin Camerer, George Loewenstein, and Martin Weber in 1989.
