Common sense, as described by Merriam-Webster, is defined as beliefs or propositions that most people consider prudent and of sound judgment, without reliance on esoteric knowledge or study or research, but based upon what they see as knowledge held by people "in common". Thus "common sense" (in this view) equates to the knowledge and experience which most people already have, or which the person using the term believes that they do or should have. According to Cambridge Dictionary, the phrase is good sense and sound judgment in practical matters ("the basic level of practical knowledge and judgment that we all need to help us live in a reasonable and safe way").
