Final answer:
Decisions or policies made to the advantage of historically nondominant groups are referred to as affirmative action, which aims to rectify past discrimination and promote equality.
Step-by-step explanation:
Decisions or policies made to the advantage of a historically nondominant group and to the disadvantage of a historically dominant group are often referred to as affirmative action. This concept involves active efforts by government or businesses that give special rights to minorities in hiring, promotion, or access to education to make up for past discrimination. It is a measure that can be seen as counteracting institutional discrimination such as white privilege, where benefits are received simply by being part of the dominant group. Affirmative action is one way to address and remedy the inequalities that have resulted from historic discrimination and is often accompanied by other measures such as antidiscrimination laws to promote equality and reduce earnings gaps among different groups.
