What term describes the belief that one's race is superior to others?

The belief that one's race is superior to others is accurately described as racism. This term encompasses the ideology that asserts inherent differences between races, often leading to the belief that certain races possess characteristics, abilities, or qualities that make them superior or inferior compared to others. Racism can manifest in various forms, including personal prejudice, systemic discrimination, and institutional policies that favor one race over another.

Ethnocentrism refers to evaluating other cultures based on the standards of one's own culture, which does not inherently imply a belief in racial superiority but rather a viewpoint that one's own culture is central or superior in some aspects.

Discrimination is the act of treating individuals unfairly based on their race, ethnicity, or other characteristics, and while it can arise from racist beliefs, it itself does not encompass the underlying ideology of superiority.

Bigotry involves intolerance towards those who hold different opinions, beliefs, or characteristics. While bigotry can intersect with racism, it is a broader term that is not limited solely to race.

Thus, the definition and implications surrounding racism specifically highlight the belief in racial superiority, making it the correct choice in the context of the question.
