The curse of knowledge is a cognitive bias that occurs when an individual, who is communicating with others, assumes that others have information that is only available to themselves, assuming they all share a background and understanding. This bias is also called by some authors the curse of expertise.
One way to overcome the curse of knowledge is to use concrete language and examples, rather than abstract or technical terms, when explaining something to someone who is less knowledgeable. Another way is to use stories or analogies that illustrate the main points and make them more memorable.
