There's something cultural going on here too.
How many of you have experienced a person (in my experience all women, but surely not exclusively) who, when the conversation turns to something they don't understand, always limited to the STEM realms, they make a stupid face, shake/flap their hands in the air, and say something like, "oh, my, tech geek talk. Beep beep, bloop bloop, blah, blah, blah, hahahahahaha"? I've heard them referred to as a "Science Goose" as that's sort of what the behavior looks like, but there's probably a better term. I've seen it parodied on TV too, so it's not a local thing.
These people seem otherwise sane, but the behavior is something they must feel is acceptable. I'm sure the psychology is straightforward, about making themselves feel better by mocking that which they do not understand, but it's got to have cultural support or more people would just think that they're rude assholes for conducting such displays. Personally, if I don't understand something I find that intriguing and an opportunity to ask questions, and I was reared in the same culture (I think...).
Hit me with your thoughts, gentle readers.
