So I know this site operates out of the UK, so I figured I might be able to get a good answer to this question. Please let me know if this whole line of thinking is offensive.
Anyway, I live in the United States, and I had to learn how to explain somewhat complicated things to children because of my daughter. I had trouble turning this off, and so I'd end up making way simpler explanations with simpler words just in general -- like at my engineering job. I would momentarily cringe when I did this because I expected people would get mad about this, but it was actually the opposite: people seemed to appreciate it. It has actually gotten me ahead at work.
Anyway, for about a year, whenever my brother would come over, he'd use YouTube to put on Countdown, Only Connect, and other shows like that from the BBC. These shows were shocking to me because it seemed like UK audiences were okay with being expected to....well....think! Most popular game shows over here are physical challenges or superficial rote memorization trivia.
Am I onto something here in terms of culture between the UK and the US? And also, just to get ahead of this accusation, I'm not trying to accuse certain people of being stupid or something, but just that culturally it seems that in the US it's mildly offensive not to make things perfectly mentally easy for someone.
