Has there been any studies done on this topic? I personally am very intrigued to learn more about increasing rates of narcissism in modern societies. I am especially interested in narcissism in places like image boards. I am a 2nd yr university student and I work at the mall selling perfume to people who walk by, and I have noticed that younger people seem more self centered and narcissistic. They seem to be only interested in talking about themselves, even in settings where their personal lives are not relevant, they can't seem to abstain from inserting meaningless anecdotes about themselves, even if they add nothing to the discussion. For example, the other day I was talking to this customer and they for some reason started telling me about their job and their family. My sister does the same thing all the time.

Has there been any scientific investigation onto this fascinating and most pertinent phenomenon?
