I've clicked on about 10 of those articles over the years. Maybe it would help to realize that some of the authors express strong traits of NPD and are projecting their mental contents on others.

Other times what they are describing are borderline behaviors, while the author is the one who seems to have NPD traits.

I sometimes find it interesting that they don't recognize those traits within themselves, but you can't take any of those articles seriously. They are more like tabloid articles.
