Breaking Assumptions
Most limits in thinking are not real — they are assumptions we haven't questioned. Learn to identify invisible assumptions and discover the freedom that comes from questioning them.
Let's Learn
What you will learn today
Learn to identify hidden assumptions in problems and deliberately challenge them — unlocking solution spaces that are otherwise invisible.
The Surgeon Puzzle
A father and son are in a terrible car accident. The father dies at the scene. The son is rushed to hospital, where the surgeon looks at him and says: 'I cannot operate on this patient — he is my son.' How is this possible? Most people spend time thinking of explanations (step-father, adoption) before the simplest answer arrives: the surgeon is the boy's mother. Why does this take time? Because 'surgeon = male' is an assumed — and invisible — constraint. We did not notice we had assumed it.
What Assumptions Are and Why They Are Invisible
Assumptions are beliefs we treat as facts without questioning them. They are usually invisible because: • They seem obviously true • Everyone around us shares them • They have 'always' been true in our experience • Questioning them feels strange or disrespectful Examples of assumptions that seemed obvious until someone broke them: • 'The earth is flat' — obvious, until navigation proved otherwise • 'Information must be physical' — obvious, until digital communication • 'Music must be purchased as a physical object' — obvious, until streaming • 'School must happen in a building' — obvious, until remote learning Every assumption that has been broken created a new world of possibilities.
How to Surface Hidden Assumptions
You cannot break an assumption you cannot see. Here are four ways to surface hidden assumptions: 1. List every 'must', 'always', 'never', 'obviously' in how you describe the problem 2. Ask: 'What would we lose if we removed this element?' 3. Ask: 'Who decided this was necessary?' (The answer is often: nobody — it just grew) 4. List the reverse: 'What are the opposite rules to everything I assume is true here?' Each surfaced assumption is a potential unlock — a door that might open into a new solution space.
- Find every 'must', 'always', 'never' in the problem description
- Ask: what would we lose if we removed this?
- Ask: who decided this was necessary?
- List the opposite of every assumption
📐 Assumption Breaking in Business History
Assumption: 'Taxis must be owned by taxi companies' → Uber/Ola broke this: private cars become taxis through a platform. Assumption: 'Hotels must own hotel rooms' → Airbnb broke this: private homes become hotels through a platform. Assumption: 'Encyclopedias must be written by paid experts' → Wikipedia broke this: anyone can contribute; the community corrects. Assumption: 'Music must be bought' → Spotify broke this: music becomes a subscription service. In every case, a massive established industry was disrupted by someone asking: 'Does this really have to work this way?'
The Most Powerful Assumption to Break
The most powerful assumption to break is always the one everyone in the room takes most for granted. In any group solving a problem, the first step is to make the 'obvious' explicit: 'We all assume X is fixed. What would happen if it were not?' The obvious assumption is the hardest to break because it is invisible — but when it breaks, it creates the most surprising and valuable new territory.
Assumption Audit
Take the concept of 'homework'. List every assumption embedded in how homework works: For example: • Homework is done at home (assumed) • It must be on paper (assumed) • It is assigned by the teacher (assumed) • It is for individual completion (assumed) • It is checked/graded by the teacher (assumed) For each assumption: what would be possible if you broke it? Write one specific idea that only exists after each assumption is broken.
Breaking Assumptions
Assumptions are invisible constraints we have never questioned. Every major innovation broke an assumption that seemed obvious. Surface assumptions by listing 'must/always/never' statements. Then deliberately break each one and see what becomes possible. The assumption everyone is most certain about is usually the one most worth questioning.
You now have the tools to make invisible assumptions visible — and to question them deliberately. This is one of the most powerful creative moves you can make.

Key Points
முக்கிய குறிப்புகள்
- ✓An assumption is something we believe without checking if it's true
- ✓Many creative blocks come from assumptions: 'this is the only way', 'that's impossible'
- ✓Classic example: Nine-dot puzzle — people assume lines can't go outside the dots
- ✓Explicitly listing assumptions makes them visible — then you can test them
- ✓Breaking the right assumption is often the creative breakthrough
