Brainstorming Without Limits
Good brainstorming has rules: no judgement, quantity over quality, wild ideas welcome. Learn why these rules exist and practise generating ideas you'd normally dismiss.

What you will learn today
Learn effective brainstorming techniques — and understand why the rules of creative generation are different from the rules of evaluation.
The Worst Possible Idea
Ready? We are going to brainstorm the WORST possible school timetable. Try to make it as terrible as possible. • All exams on Monday morning • Maths right after physical education (tired brain) • Lunch at 10am and nothing else till 4pm • PE on the hottest day of the week at midday • All the favourite subjects on Friday afternoon when everyone is distracted Now: flip each one. You have just designed a genuinely good timetable by inverting terrible ideas. This is 'worst possible idea' brainstorming — one of the fastest ways to generate creative solutions.
The Rules of Effective Brainstorming
Most people brainstorm wrong. They generate an idea, immediately evaluate it, discard it as impractical, and generate the next one. The result is a short list of safe, conventional ideas. Effective brainstorming separates the generation phase from the evaluation phase completely: Generation rules: 1. No criticism during generation — even in your own head 2. Go for quantity — 50 ideas beats 5 ideas, every time 3. Wild and silly ideas are welcome — they can be refined 4. Build on others' ideas — 'yes, and...' not 'yes, but...' 5. The obvious ideas come first — write them down fast and move past them Evaluation comes later, with different rules. Never mix the two phases.
- No criticism during generation
- Quantity over quality
- Wild ideas welcome
- Build on ideas with 'yes, and...'
- Write down obvious ideas quickly and move past them
Why the 100th Idea Is Often the Best
In creative research, the first 20 ideas generated are almost always the obvious ones — the ideas everyone thinks of. They are not wrong, but they are not surprising either. Ideas 20–50 start to get unusual — the brain has exhausted the obvious and starts reaching into less-familiar territory. Ideas 50–100 are often where the genuinely surprising and valuable ideas appear — the brain is now working hard, making connections it would never have made if it had stopped at 20. This is why brainstorming sessions should have a minimum idea count target — not a time limit. 'We do not stop until we have 50 ideas' produces far better results than '30 minutes of brainstorming'.
📐 IDEO's Brainstorming Culture
IDEO is one of the world's most famous design companies (they designed the first Apple mouse, the first laptop, and thousands of other products). Their brainstorming culture is legendary: • Their rooms are covered in sticky notes from previous sessions • They have a 'defer judgment' rule: no idea is criticised during generation • They set explicit idea quantity targets: 'We need 100 ideas in 60 minutes' • They do 'warm-up rounds': everyone shares a terrible idea first — it signals safety • They build on ideas: 'Yes, and...' is the only allowed response Result: their first-round ideas are not usually the best ones. The breakthrough comes after the obvious ideas are exhausted.
Brainstorming Alone vs Together
Surprising research finding: people brainstorm more and better ideas alone than in a group — but the group phase adds value at the EVALUATION and COMBINATION stage. Solitary brainstorming avoids: • Social inhibition (not wanting to look silly) • Anchoring (one person's idea limits what others think of) • Domination (louder voices fill the room) Group brainstorming adds: • Unexpected combinations of individual ideas • Building ('yes, and...') • Diversity of starting perspectives Best approach: brainstorm alone first → share and combine in group → evaluate together.
The 50-Idea Challenge
Problem: How might your school make students feel more welcome on their first day? Set a timer for 10 minutes. Write 50 ideas. Any ideas. Terrible ones count. Impossible ones count. Obvious ones count. Rules: • No crossing anything out • No 'that won't work' — just write the next idea • If stuck: write the worst possible idea for 30 seconds, then return When done: circle the 5 most interesting. Not the most practical — the most interesting.
Brainstorming Without Limits
Effective brainstorming separates generation from evaluation. No judgment during generation — quantity is king. The best ideas come after the obvious ones are exhausted. Brainstorm alone first, then combine in a group. And 'worst possible idea' inverted is a powerful shortcut when stuck.
You now know how to brainstorm effectively — and why most people do it wrong by mixing evaluation into the generation phase.

Key Points
முக்கிய குறிப்புகள்
- ✓Rule 1: No judgement during generation — wild ideas are welcome
- ✓Rule 2: Quantity over quality — more ideas = more raw material to work with
- ✓Rule 3: Build on others' ideas — 'yes, and...' not 'no, but...'
- ✓Rule 4: Stay focused on the topic — don't drift into unrelated discussions
- ✓After brainstorming: sort, combine, evaluate — this is when judgement comes back
