Current-events knowledge in adults: An investigation of age, intelligence, and nonability determinants

This study expanded the scope of knowledge typically included in intellectual assessment to incorporate domains of current-events knowledge from the 1930s to the 1990s across the areas of art/humanities, politics/economics, popular culture, and nature/science/technology.  Results indicated that age of participants was significantly and positively related to knowledge about current events.  Moreover, fluid intelligence was a less effective predictor of knowledge levels than was crystallized intelligence.  Personality (i.e., Openness to Experience) and self-concept were also positively related to current-events knowledge.  The results are consistent with an investment theory of adult intellect, which views development as an ongoing outcome of the combined influences of intelligence-as-process, personality, and interests, leading to intelligence-as-knowledge
