Answer:
Minority Group.
Step-by-step explanation:
A minority group can be defined as the group of people who are singled out from the society based on their culture and appearance. Such groups are often a victim of discrimination. The people who are often singled out are based on gender, race, ethnicity, religion, etc.
The study of the article "If You're Sexist, People Will Think You're Racist and Vice Versa" will be generalised as a minority group. It is because, as stated, members of stigmatised (minority) groups were prejudiced or discriminated but another group (majority). The results will reveal that the groups which faced prejudice belonged to a minority group.
So, the correct answer is a minority group.
