General knowledge is an important component of crystallized intelligence and is strongly associated with general intelligence, and weakly associated with openness to experience. Studies have found that people who are highly knowledgeable in a particular subject tend to be knowledgeable in many. GK is thought to be supported by long-term semantic memory ability. General knowledge has been defined in differential psychology as culturally valued knowledge communicated by a range of non-specialist media and encompassing a wide subject range.
