The context here might be that we are in a design review - you are presenting a design. Maybe it's verbally, but maybe it's a document.
Ideally it's a document, so you can describe it by writing it down.
But if someone asks a hard question that you didn't prepare for, well you still have to make a best effort to answer it verbally.
You can use "I'll write down my thoughts and get back to you" to SOME things, but not every time.
My original context was rather that of a junior developer asking a more experienced developer what choices to make, and then questioning them. Which is good, but sometimes the knowledge gap is just too wide to deal with then and there.
