Normally I have no problem letting things develop naturally as we RP. Even if there's a few logical kinks, I usually can smooth over them in my head. It's just I feel like everything has to be clear, otherwise we will flat out say the exact opposite things. Like with the whole "People have died from this" "No they haven't" thing. We worked it out and I'm fine with the decision we made on it, but I'm really afraid of our brains just not being in the same place on stuff, and having it lead to obvious plotholes.

I mean, on a lot of things you're a really forceful partner, and I try to sort of let you be, because sometimes it's fun being dragged along in a story, and I know you are a better writer than I am. But I need the technology and history to make sense for me, partially because I know a lot about historical trends (forced through the AP classes in high school) and I have a personal attachment to technological history as an aspiring engineer. 

Furthermore, it's even more important with my characters in this, due to how long they've been alive. It's not history to them, it's the lives that they have lived. Now I have no problems making unilateral decisions on this, and just having them come up IC, but honestly, I'm afraid you won't like the decisions I make. And if we disagree, then instead of one of us changing, we will both just write totally different things. That's why I'm trying to clarify this stuff.
