The word "hip" (analyzed in the previous post) reminds me of another word which has fallen out of fashion in the past few years, but which you heard a lot a decade ago: intelligentsia. This was a word which the East Coast media elite used to describe people who were, uh, just like them: liberals who had gone to prestigious universities where they majored in soft subjects and were brainwashed into being politically correct.
Strangely, the word was never used to refer to physicists, or engineers, or mathematicians, or experts in any number of other arcane fields which actually required a high IQ. Rather, it denoted a certain set of precious sensibilities.
Ironically, the self-anointed "intelligentsia" found the concept of intelligence itself absolutely abhorrent: anybody who actually thought that IQ was anything other than a "social construct" couldn't possibly be a member of the "intelligentsia." Yet this didn't keep them from using the term. (There didn't seem to be any members of the intelligentsia aware of this irony.)
Those of us not members of the intelligentsia were, by implication, members of the "dumbsia." (In previous generations a slightly different kind of snob would refer to these people as "the great unwashed.") The intelligentsia obviously felt that these unenlightened masses should have been kneeling at their feet, absorbing their proper way of thinking.
Thankfully that word has fallen out of favor, since its preening nature was obvious to everyone but the intelligentsia, who finally cottoned onto its implications.
