Who defines what is common sense?

1. Common sense has no universal meaning.
2. An individual defines common sense.
3. What is common may not make sense to another individual.
4. What is sense may not be common to another individual.
5. Sense is individually defined. The society defines the norms.
6. There is nothing obvious to everyone.  “It is common sense phrase” is misleading. The phrase should be used to teach an individual what limitations he/she does not portray, as defined by the society as “ common sense”.
7.  You may correct act(s) considered to be common sense by showing/teaching the individual how to conform to society’s definition of common sense.
8.  Individuals have senses that are not common to others, “THERE IS NO COMMON SENSE”.
9. I am stupid to request a universal definition of “COMMON SENSE” from my esteemed audience.
