Social constructivism explains that the interaction people have with their environment creates all knowledge. The idea of normal is constructed through our relationship with our surroundings. It means people will always see normality and abnormality from a social point of view.

This theory may stir up an ethical and moral debate. It is society who ends up excluding behaviors, ideas, or characteristics through prejudice and criticism. This explains how the consideration of what is normal and abnormal has changed throughout history. Normality can be considered as the process for self-regulation.
