A mistake made aloud becomes a resource for people who remained silent.

One person says the wrong thing out loud and everyone silently learns from it. The error gets examined, corrected, and understood by a room full of people who had the same confusion and would not have raised it. Whoever spoke absorbed the discomfort and produced a public good.

Be the person who asks the obvious question occasionally, particularly if you have some standing in the room. And when someone else does it, say that it was a useful question. Both of those make the next one cheaper for everyone.
