Negative Brainstorming

Choose this exercise

Purpose: Generate unconventional ideas by intentionally exploring and reversing flawed or destructive proposals.

Use it when: Use when a team is stuck on obvious answers, facing creative fatigue, or needs to loosen rigid thinking on a defined challenge.

Skip it when: Skip when the team is in acute conflict, addressing genuine safety hazards, or needing immediate operational consensus rather than divergent ideas.

Group arrangement: Subgroups of 3 to 5 people

Timing: UWT suggested timing. The source notes a brief overview; 25 minutes allows structured ideation, inversion, and debrief.

Materials and tools

• Sticky notes (1 pad per subgroup)
• Markers (1 per participant)
• Chart paper or whiteboard space (1 sheet per subgroup)
• Countdown timer

Before participants arrive

1. Write the core challenge question clearly at the top of each chart paper or shared board.
2. Divide chart paper into two columns labeled 'Worst Possible Solutions' and 'Transformed Solutions'.

Say this to open

Welcome. Today we will tackle our challenge backward. Instead of straining to find good ideas right away, your job in this round is to come up with the worst, most absurd, or most destructive solutions possible. Make them truly terrible. Later, we will flip those bad ideas into workable insights.

How to run it

1. Introduce challenge and bad solutions 3 minutes

   State the challenge question clearly. Explain that the immediate goal is to produce actively bad ideas that worsen the issue. Offer an explicit neutral example: If the problem is 'How do we encourage attendance at community meetings?', a terrible idea is 'Lock the doors and turn off the heat.' Set a timer for 6 minutes.

2. Brainstorm worst ideas 6 minutes

   In subgroups of 3 to 5, participants write one bad solution per sticky note and post them in their left column. Encourage quantity and extreme concepts. Stop when the timer sounds.

3. Invert and transform 8 minutes

   Direct each subgroup to pick 2 or 3 of their most extreme bad ideas. Instruct them to ask: 'What is the opposite of this?' or 'What useful principle is hidden inside this bad idea?' They write positive, plausible solutions and stick them in the right column alongside the originals.

4. Share transformed solutions 5 minutes

   Call the room together. Invite one spokesperson from each subgroup to share one bad idea and its transformed constructive counterpart. Keep each report to 45 seconds.

5. Debrief the exercise 3 minutes

   Lead a brief whole-room reflection using the debrief questions. Take 2 or 3 brief comments.

Debrief questions

• How was it to brainstorm on really bad solutions compared to searching for good ones?
• Which transformed idea surprised you by actually being practical?
• How can this reverse-thinking approach be used in your regular work?

Finished output: A shared chart of extreme bad solutions paired with transformed, constructive ideas.

Remote

Set up a shared digital whiteboard with two columns per breakout room. Assign groups of 3 to 5 to breakout rooms for steps 2 and 3, then bring everyone back to the main room for spoken presentations and text chat comments.

Hybrid

Pair in-person subgroups with their own physical charts and assign remote participants to a dedicated digital board. A nominated room scribe reads remote cards aloud, or remote participants present their inverted ideas during the shared report-out.

Access and participation choices

• Participants may contribute by writing sticky notes, speaking aloud in their subgroup, or placing notes silently.
• Anyone may choose to observe subgroup idea generation without offering an idea, or pass when invited to share during the report-out.

If the session gets stuck

Participants generate mediocre or realistic bad ideas instead of extreme ones.

Prompt them to aim for ideas that would guarantee complete failure, high cost, or extreme inconvenience.

Groups struggle to invert a purely destructive idea into something positive.

Ask them to identify the core mechanism of the bad idea and reverse its direction or remove its harm.
