Common Sense:

We are undoubtedly heard comment 'It's just common sense' when we are trying to justify an idea or give creeping to our viewpoint. However, In practice the claim that someone is 'common sense' is often used by people who do not wish to, or cannot explain their reasoning. There are two main dangers of saying 'it's common sense' which I have tried to explain by taking in social scientist's viewpoint.

1. It is not always common: When we describe an idea, issue, theory or whatever as common sense we often mean that it fits with our own understanding of the world. However, other people from different social backgrounds, ethnic groups, age groups, and so on might not share the same understanding. In other words, the idea, issue or theory is not common to them. Just because something is sensible that does not automatically make it common.

2. It is not always sense: Albert Eisten described common sense as 'the collective of prejudices we have acquired by the age of 18'. In other words, common sense explanations often close our minds to other possibilities. Just because something is common that does not automatically make it sensible. Some sense understandings are later proven by rational, logical enquiry and experience to be misguided and ill-informed.

Therefore, social scientists rarely justify something as common sense. They are always seeking to prove their claims and justify their theories and ideas.
