Answer:
The answer is aversive racism.
Explanation:
In contrast to plain racism, which involves mistreatment of the out-group, aversive racism refers to the avoidance of interaction with other racial groups.
It's interesting to note that, under aversive racism, people tend to deny having any racial bias. However, they have been shown to change their behaviour in the presence of a member of the out-group. This aversion might be conscious or ounconscious.
