What if before every meeting, someone said the following:
Before we get started, I just want to state that everyone in this room is important or you would not be here. We need your input. Don’t be hesitant. Feel free to disagree with anything. Just say it. We want your point of view. Speak up.
That said, there are some folks that are negative and talk too much. If this is you, please pipe down so others can speak. Please be open to all ideas. Please be positive.
I think the world would be a better place if most of us weren’t so timid. We should all feel safe to share our ideas.
