There are a few reasons why this is the case. Firstly, many people shy away from speaking up because they fear their ideas are silly. It can be frustrating and helpless, as they don't have any control over the situation.  Secondly, people shy away from speaking up because they worry about what others think of them. They may feel self-conscious and worried that their voice will not be heard or respected. And, it can make it difficult for them to open up and share their thoughts with others.  Finally, some people shy away from speaking up because of making mistakes. They may think that saying nothing will avoid any potential conflict or embarrassment. However, this often leads to more issues because it's tough to get anything done when there's silence in the room.
