Minute Mysteries

Choose this exercise

Purpose: Practice testing assumptions and refining inquiry using constrained yes-or-no questions.

Use it when: Use at the start of a meeting or learning module to examine questioning habits, test hidden assumptions, and practice active listening.

Skip it when: Skip when the session requires working on direct organizational problems or when participants are fatigued by riddle-style games.

Group arrangement: Whole group with open-floor questioning

Timing: UWT suggested 15-minute standard block based on the 10-minute inquiry window in source evidence

Materials and tools

• Facilitator reference card with mystery prompts and complete solutions (e.g., Romeo and Juliet fishbowl scenario; Monopoly car scenario)
• Whiteboard, flip chart, or digital display for writing the prompt and tracking confirmed facts
• Dry-erase marker or digital text tool

Before participants arrive

1. Select one mystery scenario from the facilitator reference card.
2. Keep the solution private and hidden from participant view.

Say this to open

I will read a short mystery with missing context. Your job as a group is to solve what happened. You may ask me any question, but I can only answer with Yes, No, or Irrelevant. Anyone can ask a question, or you can choose to just listen and track what we learn.

How to run it

1. Present mystery prompt 2 minutes

   Speak the opening script. Read the selected scenario aloud twice, slowly and clearly. Write the exact scenario clue on the board or in the shared chat so all participants can reference it continuously. Restate the response boundaries: the facilitator responds strictly with 'Yes', 'No', or 'Irrelevant'.

2. Run structured inquiry 9 minutes

   Open the floor for participant questions. Answer strictly with 'Yes', 'No', or 'Irrelevant'. For example, if someone asks 'Were Romeo and Juliet people?', answer 'No'. If someone asks an open question like 'What broke the glass?', respond: 'Please reframe that as a yes-or-no question.' If the inquiry stalls completely after 6 minutes, offer one nudging prompt such as 'Have you asked about who Romeo and Juliet are?' or 'Where did the water come from?' Stop inquiry as soon as the group articulates the core solution or time expires.

3. Verify outcome 1 minutes

   If the group names the correct explanation, confirm their deduction. If the time limit arrives before the group solves the puzzle, read the complete solution aloud so the group leaves with closure.

4. Debrief inquiry patterns 3 minutes

   Lead a brief reflection with the whole room using the debrief prompts. Invite two to three participants to share observations on how the questions evolved and what assumptions shifted during the process.

Debrief questions

• Which initial assumption held the group back the longest?
• Which specific question caused the main breakthrough, and why?
• How did listening to someone else's question change the line of inquiry you pursued next?

Finished output: A group-verified solution to the mystery scenario, or a clear public review of the full explanation.

Remote

Run in the main video room without breakout rooms. Post the initial scenario clue into the text chat and pin it or display it on a shared slide. Participants raise a virtual hand to ask a spoken question or type their question directly into the chat for the facilitator to answer in sequence.

Hybrid

Project the scenario prompt on the physical room screen and paste it into the virtual chat. Alternate questioning turns strictly between in-person participants and remote participants to ensure room voices do not dominate virtual callers.

Access and participation choices

• Participants may choose to listen and take notes rather than speak questions.
• Written questions via chat or paper slips are accepted alongside spoken questions to accommodate non-speaking participation.
• Anyone may opt out of debrief sharing without explanation.

If the session gets stuck

Participants ask open-ended questions like 'What caused the glass to break?'

Politely pause and say: 'I can only respond with Yes, No, or Irrelevant. Please rephrase that as a yes-or-no question.'

One or two vocal participants shout out questions continuously without letting others speak.

Enact a simple turn limit: after asking one question, a participant must wait until two other people ask questions before asking again.

A participant already knows the puzzle and calls out the answer immediately.

Acknowledge that they know this classic puzzle, ask them to keep the secret, and immediately switch to the backup scenario on the reference card, or invite them to help track confirmed clues on the board.

Terms used here

• Lateral thinking: Solving problems through indirect, non-obvious approaches and questioning foundational assumptions.
• Irrelevant: A facilitation response meaning the detail asked about has no impact on solving the scenario.
