How do narcissistic people take credit for successful outcomes?

Individuals with narcissism often maintain an inflated and grandiose self-image by relying on biased perceptions of their own accomplishments. When it comes to successful outcomes, research indicates that narcissists tend to take greater credit for these results, even in instances where the success was achieved through luck or chance rather than their own efforts.1

This behavior is part of a broader pattern of chronic interpersonal self-esteem regulation. Because narcissists are preoccupied with maintaining an excessively positive self-concept and soliciting admiration from others, they often engage in self-promoting and self-aggrandizing statements. Their tendency to claim credit is supported by a distorted view of their own capabilities, as they frequently overestimate their intelligence and other personal attributes relative to objective assessments. Ultimately, these actions serve to reinforce their need for external validation and their desire to be viewed as exceptional by those around them.12
