Gets everyone involved. People understand better by explaining. It’s really about learning by teaching. Generative thinking. Works well if you go around twice. Widely applicable. Can be used for almost anything. Makes a non-talkative group more talkative.
Enforce the circle. One person at a time and use a talking stick/token. Egg timers work well for Italian and Spanish groups. The more challenge the team has to stay on time, the more rituals need to be introduced/enforced.
