Yea I found this test to be really dumb just like most personality tests. What if the subject is naturally good at influencing people, considers that they themself might be special due to superior skills/intelligence, or thinks they would make the world a better place if they were to rule over it. You can't deny facts in the hope of not testing positive as a narcissist.
Choosing answers on that side of the spectrum doesn't have to be because of an irrational and unwarranted self-love. Narcissism is a negative quality indicative of unworthy self bias. On this test a non-narcissistic person could still score 10 points, which isn't fair.
Either that or I'm a dumbass with a hint of narcissism in denial.
