I HATE forms and surveys that ask for my opinion on something I have no knowledge on, mark it as manditory and don't give me a null option.
This is tied with a question that gives me 3 options none of which is my opinion.
Uninformed opinions do not feel good, there is that sense of something missing. Of cause most people do not notice missing information or contradictions. Most missing information is undetectable, but not all.
Having a sense for missing information is a form of intelligence that is not known well.
I hate people who never say "I do not know." or "I have no opinion on that." but rather give you some BS.
