We find descriptions of common sense in the domains of anthropology, artificial intelligence, and psychiatry. This is the common sense for adaptation, a form of practical intelligence that better predicts success in everyday experiences, if not real-world survival. This common sense is experienced-based knowledge rather than rule-based. When unexpected situations occur, it supports continuous assessments and decisions to adjust to the conditions at hand. Overwhelmingly practical, common-sense deals with a concrete situation on its own terms. Common sense describes cultural knowledge and behaviors. Inquiry drives practical common sense.
