Is narcissism inherited

If Narcissism is that extreme form of self-love which totally over-rules any attraction to members of the opposite sex, it is extremely unlikely that narcissism could ever be passed on to future generations.

'Personality' is the product of genetics, environment, experiences in life and, to some extent, personal choice (free will).

These factors contribute to any narcissistic tendencies a person may have or exhibit. Similarly, the degree of narcissism will also be influenced by those factors. This being so, narcissism, to a greater or lesser degree, may be inherited, but not necessarily.

To some extent, a measure of 'self-love' is natural; it is a feature of being human. But experience and maturity generally ensures that self-love does not become a person's predominant quality.
