Self-righteousness and narcissism are two different personality traits, but they can sometimes overlap in certain behaviors or attitudes. In order to understand the overlap and non-overlap between self-righteous and narcissistic traits, it is important to first define each trait individually.

Self-righteousness refers to the belief that one's own moral, ethical, or religious beliefs are superior to those of others. People who are self-righteous often exhibit a sense of moral superiority and may be judgmental or intolerant of others who do not share their values.

Narcissism, on the other hand, is a personality trait characterized by an inflated sense of self-importance, a deep need for admiration, and a lack of empathy for others. Narcissists often have an exaggerated sense of their own abilities and accomplishments and may constantly seek validation and praise from others.

Overlap:

1. Sense of superiority: Both self-righteous and narcissistic individuals tend to believe that they are superior to others, whether it is based on their morals or their abilities and accomplishments.
2. Judgmental attitude: Both types of individuals may display a judgmental attitude towards others, looking down on people who do not meet their standards or share their beliefs.
3. Need for validation: Both self-righteous and narcissistic people may seek validation and praise from others to reinforce their sense of superiority.

Non-overlap:

1. Basis of superiority: While self-righteous individuals derive their sense of superiority from their moral or ethical beliefs, narcissists base their superiority on their abilities, achievements, or personal qualities.
2. Empathy: Self-righteous individuals may still be capable of empathy and concern for others, despite their judgmental tendencies. In contrast, narcissists typically struggle with empathy and may have difficulty understanding or caring about the feelings and needs of others.
3. Focus on morality: Self-righteous people are primarily focused on moral or ethical issues, whereas narcissists may not have a strong moral compass and can be more focused on personal gain or self-promotion.

In summary, self-righteousness and narcissism can share certain traits such as a sense of superiority and a judgmental attitude. However, they also have distinct differences, with self-righteous people primarily focused on moral or ethical issues and narcissists lacking empathy and focusing on personal gain or self-promotion.
