Final answer:
Ethnocentrism and sociocentrism involve the belief that one's own cultural or social group is superior, leading to a focus on the needs of one's own group over others.
Step-by-step explanation:
The tendency to focus exclusively on our own needs and the needs of our own group is an example of ethnocentrism and sociocentrism. Ethnocentrism involves a belief that one's own culture is better than all others, which can sometimes lead to viewing cultural differences with disdain or misunderstanding. Sociocentrism refers to the tendency of individuals to prioritize the needs and values of their social group above others.
William Graham Sumner highlighted this concept by defining ethnocentrism as the view in which one's own group is considered the center of everything, and all others are scaled and rated with reference to it.
