As empty vessels make the loudest sound, so they that have the least wit are the greatest blabbers - Plato
Empty vessel or the empty vessel approach is a term describing the negative effects of how one ends up with a worthless outcome when trying to please everyone. The term is more commonly used in
psychology and
behavior analysis. Worthlessness cannot be measured, but there will be consensus among the participants that the end product does not even come close to the previously desired outcome.
To quote from a friend's friend: "Y is just making up for the lack of quality with quantity, but the quantity only ended up reflecting the lack of quality."

All in all, it doesn't mean one should always keep quiet in order to show he/she's a learned, well-informed person. Neither should one always blabber for the sake of trying to show his different point of views on certain issues. It will only further emphasize the emptiness of one in front of friends/strangers/people he/she's trying to impress.
Appropriate injections at certain points during a conversation should be done when you have structured your thoughts well and feel that you can add a few cents worth into the conversation. If you find yourself starting at the conversation having a different view from the other side BUT ending back to agree with the view of the other side, you might find yourself better not starting at all to show your emptiness.
This is not about daring to be different or creating a new perspective into certain issues.. Such things should only be done when you have gathered your thoughts well to make it work. If you find yourself coming back to initial discoveries already done earlier by others, it's better to go back to the drawing board.
My quietness during conversations is to listen in well and gather all the info spoken during a conversation. I don't speak in between conversations is because I don't want to enter without getting a full picture of what's happening. Such injections will only cause me to either be biased or make a big fool of myself. If asked for comments during a conversation, I might ask people to repeat certain points they spoke so that I ensure my thoughts/comments are based on the data collected during the conversation.
Of course my approach can fail at times, at the very least it doesn't show my emptiness that much during conversations.
