Have you ever wondered why a post-secondary education is considered to be important? I mean, the material you learn isn’t as practical as actual work experience. Or have you ever wondered why each bill of money has a specific value? I mean, it is just a piece of colored paper. Well, these two things (and many others) have social value because of social construction.
Social constructionism is this sociological theory that believes all things that have social meaning are created by individuals and by societies. In other words, individuals construct meanings for things that would otherwise be meaningless. And as more people join the group (or society), the meanings of these things become reality because large amounts of people believe it. This is the basic process of a social construct.
