What belief includes the idea of one’s nation or ethnic group being superior to others?

The belief that includes the idea of one’s nation or ethnic group being superior to others is known as ethnocentrism. This concept refers to the tendency to evaluate other cultures or ethnic groups based on the standards and values of one's own culture, often leading to a viewpoint that one’s own group is superior. Ethnocentrism can manifest in various ways, including biases, prejudices, and discriminations against those perceived as "different" from one’s own group. This belief can contribute to social division and conflict, as it fosters an "us versus them" mindset.

In contrast, nationalism is primarily focused on promoting the interests and culture of a nation, which may not inherently carry the same connotation of superiority over others. Elitism pertains more to the belief that certain individuals or groups are inherently superior due to their social class, education, or wealth rather than a national or ethnic identity. Classism involves prejudices and discrimination based on social class rather than ethnicity or national origin. Each of these alternatives has distinct definitions and implications, but ethnocentrism specifically addresses the notion of superiority linked to one’s ethnic or cultural group.
