You can open with: “We’ll spend five minutes on a quick This or That game. I’ll give two options, and you have to choose fast. No standing in the middle. Left side is the first option, right side is the second option. There is no right answer; we’re just seeing people’s preferences.”
First question: “Cats vs. dogs?” After people move, the host might say: “Looks like dogs have the room. Cat people look unconvinced. Anyone want one sentence for why cats are better?”
Then move through: “Remote work vs. office work?” “Early morning vs. late night?” “Pineapple pizza should exist vs. should not exist?”
If one question gets strong reactions, let each side send one person to defend the choice for 30 seconds.
Close with: “Great. Now we know who is team cat, who is team dog, and who is ready to fight for pineapple pizza. Let’s move into today’s session.”
