This is why user/usability/UX research is actually a _thing_. Like a discipline, a thing to learn, a thing where experience and skill matter.
Yes, you can't just "ask". But there are certainly ways to learn. Doing a major UX redesign without doing any UX research seems like asking for trouble -- and I don't trust the conclusions drawn from the outcome, still without being based on UX research, either.
