Genetic theories about whether narcissism is inherited

Research on narcissism and its genetic inheritance focuses on understanding how personality traits, including narcissistic ones, can be influenced by genetics. Here we present some key theories and findings about it:

Twin studies

It has been proven that there are higher chances of inheriting narcissistic conditions in those people who share their genes. Evidence suggests that monozygotic twins tend to be more similar in their levels of narcissism than dizygotic twins, indicating a genetic component.

Longitudinal studies

It is about temporal investigations encompassing observation and analysis of emotions, behaviors and thoughts. From this perspective, it is possible to infer that narcissism can be inherited.

Polygenic inheritance theory

Narcissism, like many other personality traits, is believed to be influenced by multiple genes instead of a single gene. This polygenic theory suggests that small cumulative effects of several genes contribute to the predisposition toward narcissism.

Likewise, DNA studies can be performed from the collection of hair, skin or other tissues of the human body.

family history

Talk to older relatives about their experiences and observations related to personality traits in the family. Sometimes family history can provide clues about patterns of behavior and attitudes that could be related to narcissism. However, this option can lead to errors in interpretation.
