Antonio Crutchfield Posted over 2 years ago The common misunderstanding between common knowledge and common sense Common sense is being capable of acting or responding impulsively to situations that might arise. It does not require any prior learning to act appropriately to that situation. It should come naturally. Common knowledge on the other hand is not natural. It is learned and learned by almost all. Now with that tid bit said; I don't know that there is really in place for using common sense. All things are learned, even the most trivial things such as tying your shoe laces. That is not to say that all things are learned by all people. Such a belief leads to the derogatory usage of the term common sense.
