Introverts often prefer to have time to reflect on topics before discussing them in a group setting. By presenting brainstorming topics a day before the session, the project manager can give introverted team members time to process the information and formulate their thoughts. This approach can help to ensure that all team members, regardless of their personality type, are able to contribute fully during the session.
