A system is described for improving decision making for individuals, groups and organizations. The system enables participants to collaboratively provide informational statements as well as supporting and opposing arguments and share them and then rate them. The system visually facilitates participants prioritizing arguments, and allows participants to rate arguments on clarity, agreement, and relevance. The system includes multiple levels of authority, both inherent and topic-assignable, which enable posts to be made visible/invisible based on authority level and/or “need to know”. The system allows decision makers to increase the reach of participants in decisions while keeping the input and process manageable yielding better decisions. All posts, ratings, and edits of posts and ratings within the system are archived along with any reasons given, and archives are reviewable by users.
