Odds are half the room had your dumb question. You were just the first one to say it out loud.

Confusion feels private and almost never is. A room full of people who each assume they are the only one lost will sit silent together, every one of them reading the silence as proof that everybody else followed. The person who speaks is not unusually slow, they are the one who stopped believing that.

Try assuming your question is common rather than stupid, and ask it on that basis. Watch how many people react when you do. Keeping a rough count for a week will change what you think the risk is.
