Three friends are having a discussion on Black Lives Matter and the nature of prejudice. Friend No. 1 says, "I believe prejudice is innate; people are born prejudiced. I think it's wired into the brain." Friend No. 2 says, "I believe prejudice is totally learned. It is taught by parents to their children." Friend No. 3 says, "I believe that prejudice is a sociocultural phenomenon. It is systemic; every society needs a scapegoat."

Define the term prejudice, three subsequent paragraphs that will interpret how the three perspectives (biological, developmental, and social psychological) explain prejudice.
