Answer: Out group Favoritism
Explanation: Generally, it is normal for people to tend to categorize themselves and other people into sets. when individuals categorize other people as being part of their group , such individuals consider themselves as grouping of others , and other people not in their circle as out group. this tends to make such individual see the other group much more than their group and to sometimes negatively classify the out group which he or she does not belong to as opposed to the in group they belong to.
Out group favoritism explains that under certain conditions, people will prefer and have affinity for one's out-group over the in-group, which can be seen in one's expression in the evaluation of the outgroup and in terms of allocation of resources.
Here, eight-year-old Jennifer, an African American, who describes the white, wealthier girls in her school as "pretty," "smart," and "nice," whereas she describes the black, poorer girls as "bossy," "average," and "chubby." is expressing Out group favoritism
