You’re likely to come across not entirely socially acceptable in either case, but that’s probably impossible to counter.
This is something that I understand, but unfortunately can't really perform for some reason. I always have to be... "honest", for lack of a better word. I will always say something that makes things worse for me because it's... just how I feel.
I used to be a chronic liar, and from a young age I had this one friend who was a living lie detector, and they trained it out of me so hard that I now obsessively tell the truth in all situations even when it would be detrimental. ;-;
In other words, even if I know just saying "ok" would probably work, I feel the need to somehow "brag" or otherwise disclose my proud ignorance, even if that only results in the literal opposite of what I want.
I'm autistic and vehemently ignore and reject most pieces of news, especially political, and that causes tons of terrible things to happen whenever some sort of spoiler gets out and I happen to see it.
It's like I'm proud of my great ignorance and having that threatened with mere knowledge sends me into a panic of some sort.
It's not just news. If I say "I don't know what that is lol" to someone, 9 times out of 10 their default response to tell me what it is (if it is some cultural/media thing) is the complete opposite of what I want, which is usually just for the other person to move on without telling.
Knowing things can't be undone, so I strive not to know most things, apparently.
