Genetic predisposition can be seen as a huge factor in the development of narcissism, a condition that is more common in men than in women.
A new study, published in the Journal of Personality and Social Psychology, suggests that the presence of this genetic predispositional trait may be one reason why men tend to be more likely to develop this condition.
The study, conducted by researchers at the University of Waterloo in Ontario, examined the relationship between personality traits, and the prevalence of narcissist traits.
The study involved nearly 20,000 people in a large Canadian survey, including over 10,000 individuals with both clinical and genetic diagnoses.
They found that those with a higher personality trait and a higher genetic predispose to narcissism were more likely than those with the opposite trait to exhibit symptoms of the disorder.
The researchers said that the results support previous research, which suggests that narcissism is a more prevalent and disabling mental illness in men, particularly in those with an elevated risk of developing it.
“Our findings suggest that narcissist personality traits are associated with genetic risk for narcissism,” said lead author Dr. Sarah Toulmin, who is also a postdoctoral fellow at the Institute of Psychiatry at the London School of Economics.
“Narcissism is not a gender-specific condition, but it does share many common features, such as a lack of empathy and concern for others, a preference for self-fulfillment over other needs, and a general sense of powerlessness.”
“Narcisism is more prevalent in males and more severe in males than in females.
This is a gender difference in the genetic predisposing to narcissistic personality disorders,” Toulmine said.
“The genetic predisposes may contribute to the more severe narcissistic personality disorder in males, as males with a greater genetic predispreposition to narcissistic-type traits are more likely, and more likely for men to be diagnosed with narcissistic personality symptoms.”
In the study, the researchers also looked at the prevalence and risk factors for the disorder among people who self-identified as “male” and “female.”
Participants in both groups had their genetic predispoisons assessed, as well as their personality traits and personality disorders.
The results showed that individuals with a lower genetic predispostposition to narcissist tendencies had a higher risk of the disorders.
Dr. Toulmins co-authored the study with Dr. Robert St. John, a professor of psychiatry and psychology at the Department of Psychiatry and Psychology at the Medical University of South Carolina, Charleston.
She and St. Johns conducted the research with a team of other researchers at Waterloo, the University at Buffalo, and elsewhere.
“The results provide compelling evidence that the genetic and environmental factors influencing the development and development of narcissistic personality are distinct,” Tulmin said.
In addition to the study’s findings, ToulMIN and her co-authors also examined the link between the genetic characteristics of people with narcissistic tendencies and their prevalence of these traits.
These findings suggested that the trait of narcissistic traits may be a more common and disabling disorder in men.
The team also found that people with high levels of genetic predispression to narcissists also had higher rates of narcissistic symptoms.
Although the findings suggest there is a genetic component to narcissistic symptoms, they do not provide a definitive answer to whether the trait is more likely in men or women.
“Although there are a number of factors that may predispose individuals to narcissistic pathology, we cannot yet explain why men are more susceptible to narcissistic symptoms than women,” Toulsmin said, noting that the link could be the result of other factors besides genetic predismission.
Narcism is an extreme form of narcissistic behavior that is characterized by lack of remorse, lack of concern for one’s self, and excessive entitlement to others.
According to the National Institute of Mental Health, narcissists are most likely to be a threat to others, with the potential to become destructive or emotionally manipulative.
They also are more prone to a lack or lack of self-worth.
