People who talk less watch more. Without the work of performing, their attention is free to run over the room, and they tend to accumulate an accurate picture of how everyone is really doing. Their read is easy to miss because they rarely volunteer it.

If you are the loud one, ask the quiet one what they think, privately and specifically. If you are the quiet one, know that your read is worth saying out loud sometimes, and that people take it seriously precisely because you do not say much. Either way the information is already in the room.
