Psychology Research Reveals How Grandiose Narcissists Inflate Their Self-Image
People with grandiose narcissism often exaggerate their abilities to maintain an overly positive self-image. New research suggests that while some focus their self-enhancement on areas where they perceive themselves to excel, others who view themselves as morally superior tend to overstate their abilities across a much broader range of domains.
The study, published in Current Issues in Personality Psychology, examined when and where narcissistic individuals are most likely to inflate their abilities. The study, titled "I am so wise: Agentic narcissism, communal narcissism, and overclaiming among Polish and Italian students," adds further nuance to psychologists' understanding of the diverse ways grandiose narcissism can be expressed in everyday life.
The findings provide insight into how self-enhancement—a common tendency to view oneself more positively than others—can become a more pronounced and strategic pattern among people with grandiose narcissistic traits.
Different Forms of Narcissism Explained
Psychologists generally distinguish between vulnerable and grandiose narcissism. Vulnerable narcissism is characterized by insecurity, hypersensitivity to criticism, and defensive behavior, with individuals often concealing fragile self-esteem behind withdrawal or emotional reactivity.
Grandiose narcissism, in contrast, is associated with confidence, dominance, and a strong desire to be recognized as exceptional. Within this broader category, researchers distinguish between two main forms: agentic narcissism and communal narcissism.
Individuals high in agentic narcissism seek admiration for qualities related to intelligence, achievement, status, and personal success. Those high in communal narcissism strive to be viewed as exceptionally kind, caring, or morally virtuous, often presenting themselves as selfless helpers or ethical role models.
Researchers further distinguish these forms according to the strategies people use to gain status. Some pursue admiration through self-promotion, while others seek to protect their sense of superiority by criticizing or devaluing those around them.
How the New Study Was Conducted
The research team, led by Weronika Zyskowska and Magdalena Żemojtel-Piotrowska from Cardinal Stefan Wyszynski University in Warsaw, studied 306 university students from Poland and Italy. Although both countries share broadly similar attitudes toward achievement, they differ somewhat in the emphasis placed on social harmony.
The researchers investigated whether these cultural differences influenced the relationship between narcissistic traits and self-enhancement. They also examined whether different forms of grandiose narcissism were associated with exaggerated claims of expertise in particular domains, such as science or social issues.
Participants first completed an overclaiming questionnaire designed to measure false claims of knowledge. They were presented with lists containing both genuine and fictitious concepts spanning agentic fields, such as physics, and communal fields, such as humanitarian work.
When participants claimed familiarity with nonexistent topics, the researchers interpreted this as evidence of exaggerated knowledge. Participants also completed a second assessment measuring the "better-than-average" effect by comparing their own characteristics with those of a typical university student.
The assessed traits included competence-related characteristics such as intelligence and assertiveness, as well as communal qualities including warmth and morality. Participants indicated whether they believed they ranked among the top 5 percent of their peers for each characteristic.
How Agentic Narcissists Exaggerate
The findings largely supported previous research on agentic narcissism. Individuals scoring high on agentic admiration consistently overestimated their knowledge and rated themselves as superior in areas associated with intelligence, competence, and personal achievement.
Importantly, these individuals did not significantly exaggerate their expertise in communal domains. Their self-enhancement remained focused on the agentic qualities they valued most, such as being especially intelligent, capable, or effective.
The rivalrous aspect of agentic narcissism showed a different pattern. Participants with high levels of narcissistic rivalry, characterized by competitiveness and hostility, displayed little association with either overclaiming or better-than-average ratings.
These individuals appeared to devote more energy to defending themselves against perceived threats than to promoting their own abilities. As a result, their pattern of self-enhancement was weaker and less consistent than that observed among admiration-oriented narcissists.
Communal Narcissists Broaden Their Self-Enhancement
The findings for communal narcissism were less expected. The researchers initially predicted that these individuals would exaggerate mainly in areas related to morality, empathy, and helping others.
Instead, participants scoring highly on narcissistic sanctity exaggerated their familiarity with both communal and agentic topics. They also rated themselves well above average on characteristics related to both morality and competence.
These findings suggest that communal narcissists do not confine their self-enhancement to kindness or moral virtue. Although they seek recognition as exceptionally ethical individuals, they also appear motivated to present themselves as intelligent, knowledgeable, and highly capable when doing so reinforces their overall self-image.
Their tendency to appear "better than average" extended across multiple domains, suggesting a broad strategy for gaining admiration and reinforcing moral authority. Claims of superior ethical character may therefore be accompanied by claims of exceptional expertise in technical or specialized subjects.
What Role Did Culture Play?
The researchers also explored whether cultural differences influenced these patterns. Because Italian culture generally places somewhat greater emphasis on communal values than Polish culture, the team expected communal forms of self-enhancement to be more pronounced among Italian participants.
However, the findings only partially supported this prediction. Among Italian students, narcissistic traits did not consistently predict exaggerated claims of knowledge, although communal narcissists continued to display a strong better-than-average effect.
The authors suggest that overconfident claims of knowledge may be sufficiently common in the Italian sample that they no longer serve as a reliable indicator of narcissistic traits. Nevertheless, in both countries, grandiose narcissism remained associated with viewing oneself as above average in personally valued characteristics.
Overall, the cross-cultural differences were relatively modest and statistically limited. The broader patterns linking agentic admiration and communal sanctity to self-enhancement appeared largely consistent across both national samples.
Limitations and Future Research
The researchers acknowledge several important limitations. The sample consisted predominantly of women, who generally score higher on communal narcissism, whereas men are more likely to display agentic narcissistic traits. This imbalance may have influenced the overall findings.
Because all participants were university students, the academic environment may also encourage displays of intelligence and knowledge. This context could have motivated even communal narcissists to exaggerate their competence in ways that reflect local social norms.
In addition, the correlational nature of the study means that it cannot establish cause and effect. The findings demonstrate associations between narcissistic traits and exaggerated self-perceptions but do not show that one directly causes the other.
Future research could include more diverse populations, such as older adults and non-student samples, while also using experimental designs that challenge participants' self-esteem. Such studies may provide further insight into how narcissistic individuals modify their self-presentation when their status feels threatened.
Why the Findings Matter
Understanding how different forms of narcissism shape self-enhancement may help people recognize manipulative behavior in workplaces, social organizations, and personal relationships. Individuals high in agentic narcissism may seek admiration through claims of exceptional intelligence, talent, or competence.
Those high in communal narcissism may present themselves as unusually compassionate, ethical, or socially responsible while simultaneously overstating their expertise in technical or policy-related matters. In both cases, these grandiose self-presentations may obscure genuine competence and underlying motivations.
The researchers suggest that recognizing these behavioral patterns may encourage more balanced and critical evaluations of exaggerated claims. Maintaining healthy skepticism toward assertions of exceptional moral virtue or extraordinary expertise may help people establish appropriate boundaries and assess others more realistically.
