Answer:
The correct answer is:
Out-group homogeneity refers to our tendency to view members of an out-group as more similar to one another than they really are.
Step-by-step explanation:
The out-group homogeneity effect causes people to perceive individuals from out of their inner groups (determined by race, gender, age, nationality, etc) as more similar among them, while members of their in-groups are perceived as more diverse. For example, Italian Americans may perceive themselves as more diverse than Americans, as same as Millenials think their preferences and tastes are more diverse than the Baby Boomer's ones.
