"Common Sense". Please tell me what you think it is. Also describe how someone displays it. Lastly, please name three public figures who display (or have displayed) common sense on a regular basis.
Common Sense is the ability to see the big picture and to address any issues with real solutions, appropriate to the problem. It is the ability to see the consequences of various actions from history in order to foretell actions that should be taken in the present and future to avoid negative consequences and promote positive outcomes.
I will use my own common sense and not mention 3 of the many public figures I feel display common sense regularly, but perhaps not always, since no one is perfect, because surely someone here would pick apart my choices. So I will pass.
Common sense is simply good judgment based on keen perception, excellent ability to analyze situations, and appropriate choices of courses of action. The more knowledge and experience in different situations the person has, the more frequently the person shows common sense.
