 Their opinions can be garnered upfront through a post-it gathering exercise or with live-voting on whose opinion they value/want replaced (via non-technical show of arms/clapping or a digital live-voting app).The group can be split into two smaller and distinct sub-groups (such as men and women, or older and younger participants), who convene separately and come up with three to four questions for the other group, which are written on cards.The participants reconvene, exchange cards, and form two circles with one subgroup inside the other and both of them facing inwards.
