Obviously, I've mixed up logic and common sense all of my life ... I thought common sense is logic applied on auto-pilot, basically.
Looking at this from my version of logic .... "IF I drive under the influence" or "IF I drive while angry" THEN "consequences" BUT common sense wouldn't require a person to think this out logically. It would just be a given.
Good common sense is just the ability to rapidly think about consequences based on already acquired knowledge before taking action.
It also covers social pressure in that it is common sense (and logical) to not rock the boat (unless, of course, you have a life raft right handy).
I was aiming towards the "shared" common sense. I get what you mean though.
