The last concept that is displayed in Crash is the sociological concept of ethnocentrism. This means that we judge other cultures by the standards of our own. Not only that, but we also believe that our own culture is superior to everyone else's. Graham and his Latina girlfriend fight and he pokes fun at her culture by calling her Mexican even though she isn't. Asian Americans speech patterns are made fun of, like the term "blaking" for braking. These characters don't celebrate or even accept the characteristics of other cultures. They only mock them, assuming the superiority of their own culture. They fail to try to understand one another through ethnocentrism. Officer Ryan makes fun of the name Shaniqua, a more common name of African American culture.
All in all, Crash is a movie full of sociological concepts. Many more could be analyzed in this paper, but the focus was on only these three. Crash is a movie that makes us both laugh
