DFSN

• A person is seen as abnormal if their thinking or behaviour violates these  unwritten rules (social norms) about what is  acceptable, is unexpected by other group members or offends in some way the other members of that society/ social group.
• P- One issue with the deviation from social norms definition of abnormality is the idea of cultural  relativism.
• E- Social norms differ between cultures  and what is considered normal in one culture may  be abnormal in another.
• E- For example, in  approximately 75 countries in the world  homosexuality is still illegal, and therefore  considered abnormal. 
• L- However, in the rest of the  world homosexuality is considered normal. The  result of this is that there is no global standard for defining behaviour as abnormal and therefore  abnormality is not standardised.
