Maybe I'm referring to the dominant ideology, but is it possible for people to get together and combine their narcissistc ideologies together and share them? Are there any good papers on this subject?
Possibly worth considering: Theodor W. Adorno. "What Does Coming to Terms with the Past Mean?" (1959) included among selected writings in "Can One Live after Auschwitz? A Philosophical Reader (2003).
Adorno wrote: "On the subjective side, in the psyche of people, National Socialism increased beyond measure the collective narcissism, simply put: national vanity. The individual’s narcissistic instinctual drives, which are promised less and less satisfaction by a callous world and which nonetheless persist undiminished as long as civilization denies them so much, find substitute satisfaction in the identification with the whole. This collective narcissism was severely damaged by the collapse of Hitler’s regime, but the damage occurred at the level of mere factuality, without individuals making themselves conscious of it and thereby coping with it."
So "Narcissis" was an actual "person" in Greece who so fell in love with himself he bacame a flower that always was by the waterside so he could see his reflection and how pretty he was. Therefore my answer is "no" in the Historical sense of the word. "Looking at the mirror" is a powerful tool in psychology though and the irony that Narcissis was a male is interesting. A collection of male narcissists ... the only thing that comes to mind is Hollywood.
It's called enthocentrism. Ethnocentrism is an inability to see things from the perspective of other ethnicities. Various forms of supremacist ideology such as white supremacism, black supremacism, and Jewish supremacism are other terms.
There is no exact translation of the concept of narcissism to collectives, because narcissism by definition only applies to individuals. However, groups of individuals can be referred to using the terms above when they display narcissism on behalf of a group identity.
