That's a bit harsh maybe? I'm not sure it's all about self confidence per se. Your mind can play tricks on you. Do you go around assuming that people you meet are lying to make fun of you? Is that thing they're mentioning the same as that thing you were reading about a few days ago? Is it lacking in self confidence to assume that it was, or to assume that it wasn't?
Regardless, at some level, it points less to self-believed knowledge, as is the premise of the article, and more to socially pressured self-presentation.
Everyone on Jimmy Kimmel who went home and thought to themselves, or told their significant other "I didn't know what they were talking about but went along with it" is contradicting the premise of the piece.
