Well, what does each alignment gain or lose from avoiding questions?
Scum might avoid questions if they don’t know how to answer them in a way that doesn’t look suspicious, right, but since doing so very obviously makes them suspicious they’ll mostly want to avoid doing that (and answering questions is a pretty easy way to look productive)
meanwhile town might avoid questions if they don’t understand the question or don’t think it’s worthwhile (Luxy in Mountainous) or if they don’t really have a good answer and don’t want to give a bad one’
I think ‘doesn’t understand the question’ is honestly a pretty reasonable hypothesis here
