Social constructionists - normative explanations

I believe social constructionists are much more likely to explain psychological phenomena through a normative explanation as opposed to a causal explanation. This can be attributed to the fact social constructionists see behaviour, roles, and human interactions as being socially constructed, meaning that humans give meaning to certain aspects in life that have significance to oneself. Norms and values are dependent from country to country, culture to culture; there are no (or very few) universals that we can see from one place to another because each group of people create meaning in different ways. In a sense, people construct arbitrary things through social interactions.

Take for example, language construction. Looking at language from a social constructionist perspective, we would see that certain words in one country (or even culture) can mean something completely different in another part of the world. For example, the word "sick" around the world is generally used to refer to oneself as being ill (ex: sorry I couldn't make it to your party last night, I was feeling sick"). However, in North America, the word "sick" can also be used to refer to something as being cool (ex: "oh my god, did you see that?! That was such a sick dunk"). In this fashion, the word sick has been used in a context to refer to something as being cool/unique.
