After years of running the same old meetup formats that every other group does (lectures, group discussions, hangouts, dinners) and not being satisfied with the results, we resolved to do better. First, we made a list of every format for group interaction that we could find, uncovering over 40 different possibilities. But we still weren't satisfied. We wanted to know what else is possible. So we started inventing our own formats, which we call "Social Experiments." We never run the same format twice, so each one is truly an experiment. Each one employs a set of "rules", "instructions" or "constraints" for the participants to follow, which are each selected for a specific purpose.
