Answer:
prejudice.
Step-by-step explanation:
An unjustified attitude towards people solemnly on the basis of their group membership such as race or gender, ethnicity, religion, political affiliation, etc, is called prejudice. These preconceived notions result in a biased attitude towards group of people, which create conflict in society. Steve's behavior is an example of prejudice because though he studied in school that native-born Americans are more likely to commit crime than immigrants, he still believes that immigrants are more likely to commit crime.
