Common sense is defined as the ability to perceive, understand and judge things and act according to it in a way that is common to nearly all people. So my main issue here is the fact that common sense is a very vague term. What do I mean? Sure some things are understanable, like Don't cross the street when a car goes on it. Yet what I have trouble to understand or appreciate is the social context in which the term common sense is applied, for example: To expose about a topic in a formal presentation to a crowd, do it well dressed, that dictates the common sense, on that case for example I find no real logic for it, I would expose it either well dressed or not in the same way, in fact I would do it better with casual clothing, yet the common sense of most people is to wear a suit or formal dress, a necktie, high heels, etc. Yet from a logical perspective, from the viewpoint of someone who always analizes everything before acting, is just ridiculous. Others situations, when "something happens" and you feel you have to act with the elements you have at your disposal, yet while most of people would do a predeterminate action yet a few one have to analize the best choice, or if the supposedly reasonable action is truly the best?, are those few wrong? Is correct to act so passively? So what about it?, the common sense?... is it something that makes sense only in the context of society or something that truly makes sense?, and what about those who "lack it?" For me at least, common sense seems like one of those many things that you either have or not and that decided if you can passively belong to a standard society or will be the "weird bug" within it. I apologize if I expressed this in such a confusing way, I'm not really good at expressing my ideas, but I hope you get the point of what I mean.
