I think it's more describing how different types of narcissistic people act out their own narcissism. They have an article on arrogant/overt narcissism too. According to that website, one group is extremely self-deprecating while the other is extremely conceited. There are several different definitions of narcissism though, and that site even defines a "normal" narcissism which is pretty interesting.
Here's the article on the Arrogant/Overt Narcissist:
The Arrogant/Overt Narcissist
c/s.
There is a massive difference between confidence and narcissism as a mental personality disorder.
Someone who is confidence by definition is a person who has a forthright belief in their ability, whilst a narcissist is a person who is unhealthily self absorbed due to an underlying mental disturbance (i.e. insecurity), both conditions are completely different.
You're right in saying peoples actions are typically self serving, but the difference between a narcissist and non-narcissist is that the narcissist expresses pseudo-confidence/arrogance primarily because of their insecurities (as the article above suggests) which typically causes interpersonal conflicts, whilst the non-narcissist doesn't.
Fair enough. Surly narcissism as a personality disorder and narcissism as a description of varying degrees of confidence are not the same thing. The problem I had with the way the article was written is that its broad generalizations could be describing
anyone. Have you ever felt sick then, upon looking up your symptoms on the internet, thought that you were sicker than you really were? That's exactly the same phenomenon here. You have a lot of responses chiming "OMG, this describes me!" in this very thread when the fact of the matter is that everyone exhibits some of these traits at some point in their life simply as a function of
being. It's not to the same degree as a classic NPD but the quoted article makes little to no distinction. You are just given a broad list of traits and categorizations with little context. It's far more nuanced than is being reported.
Let's not forget to throw
Facebook Narcissists and
Millennial Narcissists into the mix as well because there are never enough accusations of narcissism to go around.
