So many writers break this rule. We want to write about something but we don;t know 100% of the facts. In some cases you never will, but you have to learn as much as humanly possible. The worst thing you can do is think you’ve remembered something correctly.
Back it up. Look deeply into it.
You would be surprised the ideas that come from finding out information you never knew. New scenes can come out of nowhere in this search which is why I find it so valuable.
The point is it has to be believable in some avenue. You can’t just hope it lands because it won’t.
Your audience is not stupid and the best thing you can try and do as a writer is not insult them by assuming that if you don’t know they don’t either.
