Intelligence is a property of mind that encompasses many related mental abilities, such as the capacities to reason, plan, solve problems, think abstractly, comprehend ideas and language, and learn. In common parlance, the term smart, metaphorically used is frequently the synonym of situational and behavioral (i.e. observed and context dependent) intelligence.

Although many regard the concept of intelligence as having a much broader scope, for example in cognitive science and computer science, in some schools of psychology, the study of intelligence generally regards this trait as distinct from creativity, personality, character, or wisdom.
