Moderation technique: How to collect and present the swarm knowledge of larger groups effectively and efficiently.
A few years ago, I gave lectures at the DHPol on the subject of Police & Science, each time to at least one study group, often to two combined groups, i.e. 25 to 50 students. However, I found it important to involve the "audience" in this very exciting and often controversial topic. For this reason, I came up with this method and it has become my favorite method for collecting opinions, ideas, etc. very efficiently, even in larger groups. It is also often very funny to implement - I'll explain why in a moment.
