It depends. Some people will relentlessly mock you for being wrong, no matter how you handle it. At work I have no problem admitting I messed up something, there’s no point and always it’s better to just fix it, right?
But with my ex, he was just dead judgemental. Might as well double down if I wasn’t sure since my accuracy rate was higher than his.
With husband I can just say I don’t know and it’s fine. On the occasion I send him something not factual I do send correction there is no penalty, for lack of a better word.
