The art of "yes, and" rather than "yes, but" is actually very difficult. I think that in some cultures this is indeed more pronounced than in others. And what follows probably in some families it is more prevalent than in others. And what follows it's not as simple as learning the start of the sentence going "yes, and", it's about the whole perspective, which if one hasn't learnt as a child, will be difficult to gain in adulthood. I see it as keeping the other person feel good about themselves being more important than getting the answer right. Because in the end there is no right answers. I still get it wrong most of the time, but I just recently started to see how important this is!
I really got it when I recently listened to a podcasted psychological debate and the two people kept on agreeing with each other, each of them giving a totally different perspective on a topic. My first reaction was "what a superficial bullshit!". And after a while I reflected on my reaction and realised that both people had perfectly enough time and space to express their opinion, and I'm sure they both left the debate feeling lifted up and appreciated by their partner, even though their opinions varied. Is this not a better outcome than feeling exhausted and leaving with strained self confidence? Not mentioning that listening to that was actually pleasant, as opposed to listening to a verbal fight.
Getting your conversation partner in the right emotional state is so crucial! There is no success talking with someone who is in a defensive emotional state. I completely, totally, didn't realise this even matters! I saw caring about someone's emotional state as.. below my standards. I thought that it should not be MY duty. I expected the other person to be processor-like precise and independent of their emotions when it came to topics other than emotions, e.g. work. Not that I was every able to do it, but I was expecting people to be constantly trying to do it. I guess I had this mindset because my parents would most often explicitly refuse to acknowledge my emotions. I learned that it is my duty to keep my emotional state out of the way, and I would expect others to (at least try to) do the same. And I would get really aggressive and picky when they wouldn't.
