Common sense is simply what the majority believes it to be. That's the reason the word "common" is used. It doesn't mean it's good or true to outsiders of that group, and who believes as something is "common sense."
No, the word "commonsense" means what the fluent and literate speakers of English mean by it, as do all English word do. That is why there are dictionaries with inform us how fluent and literate speakers of the language use the terms defined in the dictionary. In fact, people in general, are very bad lexicographers, and are often bewildered when asked to define a term in their language. Not that they do not know how to
use the term, because since it is a term in English, they, as fluent English speakers do, of course, know how to use the term in ordinary conversation. So, in that sense of "knowing the meaning of a term" they, of course, know what the term, "commonsense" means. But in the sense of knowing the meaning of a term in which it implies being able to
define the term correctly, most speakers of the language (as I pointed out) do a very bad job with that task. (This has, by the way, been studied). Professional lexicographers collate many examples of how a word is actually used in conversation, in writing, and in other ways, and then they reach a collective decision on the definition of the word in question (or, frequently, when the word is used ambiguously, several decisions about the definition of the word). Then they formulate the dictionary entry with is a report as to how the term is actually used by fluent speakers of the language. This report simply reports how the word is actually used. It is a matter of fact. Not how anyone like to use the word. That is irrelevant.
You can, then, look up the term, "commonsense" in a reputable dictionary (say) the
American Collegiate Dictionary and find out what the word mean: not what it should mean, not what anyone likes it to mean, but what, in fact, it does mean. I think you will find most good dictionaries will define "commonsense" as sound and prudent judgment, or something to that effect.
