Social constructionism questions what is defined by humans and society to be reality. Therefore, social constructs can be different based on the society and the events surrounding the time period in which they exist.[2] An example of a social construct is money or the concept of currency, as people in society have agreed to give it importance/ value.[2][3] Another example of a social construction is the concept of self/ self-identity. [4] Charles Cooley stated based on his Looking-Glass-Self theory: "I am not who you think I am; I am not who I think I am; I am who I think you think I am."[2] This demonstrates how people in society construct ideas or concepts that may not exist without the existence of people or language to validate those concepts.[2][5]
