Doubt in Action: Deconstructing a Real Brief
Doubt is a powerful creative asset.
Doubt makes some people uncomfortable. But it's the perfect state of mind to start solving problems.
Your first idea is rarely your best; it is simply the most obvious one. It is safe, recognizable, and designed to avoid discomfort, allowing it to meander through the approval process with minimal resistance. Consequently, it is released into the world much like most advertising: predictable and invisible.
This is where doubt becomes essential. Unless you challenge convention, you will continue to view problems through the same tired lens. Doubt is the catalyst for unconventional thinking, enabling you to create work that captures attention and provides your clients with a genuine competitive edge.
Paul Lavoie built TAXI into one of Canada's most celebrated agencies with doubt as the cornerstone of his philosophy. The agency's mantra remains: Doubt the Conventional. Create the Exceptional.
The TAXI Mantra: Doubt the Conventional. Create the Exceptional.
Doubt has a clear purpose and is used most often at the beginning of problem-solving. It is the first creative act. Questioning everything. It is your creative partner, forcing you not just to think but to always think differently.
Paul Lavoie smiles while holding a vintage taxi sign against a terracotta wall in an archival photograph.
That's also why Paul shunned the idea of a creative department at TAXI. He preferred building a creative company β where everyone had permission to think differently in the pursuit of excellence in their respective tasks. Doubt wasn't reserved for the people with 'Creative' in their title. It belonged to everyone.
Doubt is the foundation of critical thinking. Critical thinking is the driving force of every innovation we know. And by the way, Doubt doesn't care if you are using AI or a pencil. It only cares about giving you an advantage in any medium you use.
Doubting Doubt?
Doubt does carry a lot of negative baggage. Uncertainty. Fear. Paralysis leading to confusion or indecision, making it difficult to take action or make choices.
Paul likes the word doubt precisely because it's a vulnerable one. It suggests feelings of uncertainty, hesitation, a lack of conviction. And that, it turns out, is a perfect state of mind to start solving problems. It makes you ask questions and challenge conventional assumptions.
Doubt is the little voice in your head that says "What if?" β and pushes you toward solutions that are different. Fresh. Engaging. Exceptional.
Key insight: Doubt is skepticism β but never for its own sake. It's skepticism in service of a better, more exceptional creative outcome.
Doubt Means Questioning the Question
Doubt is the operative word. When problem-solving, doubt means to question. Even questioning the question that was given to you. Einstein said that if he had 20 days to solve a problem, he would spend the first 19 days figuring out what the true question actually was.
Unless you doubt convention, you'll keep looking at problems the same way. And the results will show it.
Pro tip: The brief is not the problem. It's a description of the problem as someone else sees it. Your job is to find out if they're right.
Setup
Choose your brief. Use one of the following:
A real brief you're currently working on (ideal)
A recent brief you've already completed (useful for seeing what you missed)
This hypothetical brief if you don't have one available:
A regional bank wants to attract younger customers (ages 25β35). They want a campaign that feels "fresh and modern" and communicates that they're "not like the big banks." Budget is modest. Timeline is six weeks.
Print it out or write it at the top of a blank page. Give yourself room to work.
Instructions
Work through each step in order. Don't skip ahead. The sequence matters.
Step 1 β State the obvious.
Write down what the brief is literally asking for. No interpretation yet. Just what's on the surface. One or two sentences.
Step 2 β List your assumptions.
What is the brief taking for granted? What does it assume about the audience, the problem, the category, or the solution? Write down at least five assumptions. Push past the easy ones.
Step 3 β Interrogate each assumption.
For each assumption you listed, ask: Is this actually true? How do we know? What if the opposite were true? You're not trying to be contrarian β you're trying to find where the brief is leaning on shaky ground.
Step 4 β Find the real problem.
Based on your interrogation, write a single sentence that captures what you now believe the actual problem is. This may look very different from what the brief originally stated. That's the point.
Step 5 β Apply Lavoie's Doubt Prompts.
Prompt AI or your creative partner with these doubt prompts and see where they take you:
Sacred cows make the best hamburgers. What is deemed sacred in the category β and fuck with it. Suspend those notions entirely.
Question the assumptions you have about the problem. What if the opposite were true?
Create a shit show. Reverse-think the problem. What steps would you take to ensure failure? You may find a nugget along the way.
Relate the problem to something unrelated. This can spark new ideas by drawing parallels between different situations.
Doubt conventional rules of success. Embrace failure: view failures as learning opportunities. Analyzing what went wrong can provide valuable insights for future attempts.
Step 6 β Name a direction.
If you had to solve this real problem with one idea β one image, one line, one gesture β what would it be? Don't polish it. Just name it. The goal isn't a finished concept. It's a direction.
Step 7 β Reflect on your creative philosophy.
Look at the direction you arrived at. What does it say about how you see the world? What values or beliefs shaped where you ended up? Write two or three sentences connecting your answer back to your own point of view.
Quick Quiz: Is Your Doubt Working?
Before you move on, check your thinking against these questions. Answer honestly β no one's grading you.
1. Did you question the question?
The brief gave you a problem. Did you accept it at face value, or did you interrogate whether it was the right problem to solve?
A) I worked with the problem as stated.
B) I pushed on it and found a different β or deeper β problem underneath.
2. Which of Lavoie's Doubt Prompts hit hardest?
Look back at Step 5. One of those five prompts probably cracked something open. Which one β and what did it reveal?
4. Did 'No' show up yet?
If you shared your direction with someone and they nodded along without hesitation, that's a warning sign. A direction worth pursuing usually earns at least one raised eyebrow. Did yours?
Use these questions as a gut-check, not a scorecard. The goal is sharper thinking β not a passing grade.
Expected Outcome
By the end of this exercise, you should have:
A written record of your assumptions and where they broke down
A reframed problem statement that goes deeper than the original brief
A rough creative direction rooted in that reframed problem
A clearer sense of how your personal creative philosophy influences your thinking
Don't judge the quality of the idea you land on. That's not what this is about. What matters is the quality of the thinking that got you there.
One Final Thought
Ok β you have your new idea and you start sharing it. Paul's advice: make 'No' your bitch.
A black and white archival photograph shows Paul Lavoie leaning in playfully next to a woman.
'No' is a silent alarm. If your idea isn't meeting some resistance, you should start to worry. It's your first hint it's docile and predictable. But when 'no' is sounding off like a five-alarm fire, it's your cue that you're on to something great and worthwhile.
Make 'no' part of the creative process and put it to work.
This is what Doubt looks like in practice β not a flash of inspiration, but a disciplined process of questioning your way to clarity. Do it enough times, and it stops feeling like work. It starts feeling like instinct.
That's the goal.
Note: Paul Lavoie and TAXI wrote a book on Doubt. It goes deeper. Seek it out.
Exercise0 / 5 steps
1
Read the brief below carefully. A mid-sized Canadian coffee brand wants a campaign to 'increase brand awareness among 25β40 year olds and communicate that our coffee is made from ethically sourced beans.' Take 2 minutes to read it as if you've just received it from a client. Don't start generating ideas yet.
2
Apply the 'Why' test. Write down at least 3 questions that challenge the assumptions in this brief. Start each question with 'Why' or 'What if.' Push past the obvious questions.
3
Find the real brief. Based on your questions, write one sentence that reframes the brief as a more specific, more interesting problem to solve. It should be different from the original brief β more focused, more human, or more honest about what's actually at stake for this brand.
4
Apply radical simplicity. Based on your reframed brief, write down the single most important thing this campaign needs to make someone feel or believe. Not a tagline β just the one human truth at the center of the idea. If you find yourself writing more than one sentence, you haven't found it yet.
5
Reflect on your process. Write 2β3 sentences answering this question: What assumption in the original brief did you find hardest to question β and why? This reflection is the most important part of the exercise. Paul's philosophy is built on the belief that knowing how you think is as important as what you think.

Frequently Asked Questions
No β and that's the point. The exercise is designed to develop your thinking process, not test your ability to arrive at a predetermined answer. What matters is the quality of your interrogation, not the specific direction you land on.
Yes. You can prompt AI directly with Paul's doubt prompts to see where they take you. But use it to sharpen your thinking, not to replace it. Constructive Doubt is about the quality of the questions you ask, and that has to come from you.
