Spotting conversational narcissism

Conversational narcissism was a term coined by sociologist Charles Derber, who, concerned with power imbalances within American society, examined rampant individualism and egotism within casual conversations among friends and work colleagues. He noticed two very different responses within the chatting:

A support response happens when a person enables the conversation to continue to focus on the other person. For example: “You say you’re not feeling good. What is it that you’re not feeling good about?”

A shift response happens when a person takes the conversation away from another person. For example: “You say you’re not feeling good. I’m not feeling good either. But I’m better than I was yesterday. Yesterday was really bad...”

Any thoughts on this particular subject?
