You have an idea. It doesn’t matter if it’s a plan to improve a workflow at your job, a concept for a community project, or a creative endeavor you’ve been dreaming of. The moment an idea takes shape, the first impulse is to share it, to see if it resonates with others. So you turn to a friend, a colleague, or a family member and lay it out.
And almost invariably, the response you get is positive. “That’s a great idea!”, “Wow, I would totally use that.” or“You should definitely do that!”
You walk away feeling validated, confident that you’re onto something. But you’ve just encountered a dangerous trap. You have received a compliment, not useful data. This interaction is why so many well-intentioned ideas, big and small, fizzle out or fail to solve a real problem. We ask for opinions and, in return, get polite but misleading feedback that can lead us down the wrong path.
This is the core problem Rob Fitzpatrick tackles in his seminal book, “The Mom Test”. It’s a pragmatic guide that fundamentally reshapes how we seek feedback. It teaches us how to cut through the noise of good intentions to uncover what people truly need, want, and value.
This article breaks down the enduring wisdom of its principles as timeless lessons for anyone trying to validate an idea.
To help you put these concepts into immediate practice, a detailed tactical field guide and question cheat sheet are included in the appendix.
Stop Pitching Your Idea, Start Exploring Their Life
The foundational principle is simple but transformative: Talk about their life, not your idea.
When you pitch your idea, the conversation becomes about your creation. The other person is now in a position to judge it, and social pressure — whether from friendship or workplace etiquette — encourages them to be supportive and avoid conflict.
To get real insights, you must shift your role from a presenter to a curious investigator. You are no longer seeking approval; you are seeking to deeply understand their world as it exists right now.
This means deflecting compliments and avoiding the temptation to explain your solution. Instead, you steer the conversation toward their past experiences, their current frustrations, and their existing behaviors related to the problem you think your idea solves.
You are not asking to validate your answer; you are asking to help you better understand their question. This approach minimizes bias and maximizes the chances of uncovering an authentic need.
The Art of the Question
The quality of your insights depends entirely on the quality of your questions. The principles draw a hard line between good, fact-finding questions and bad, opinion-seeking ones.
Bad Questions are almost always hypothetical and future-facing. They invite speculation, which is an unreliable predictor of behavior. Questions like, “Do you think you would…?” or “Could you see yourself using…?” are invitations for people to tell you what they think you want to hear. This generates “fluff” — vague, non-committal answers that feel positive but provide no actionable data.
Good Questions are specific, open-ended, and anchored in the past. They uncover facts about actual behavior, problems, motivations, and constraints. The goal is to get them telling stories about their life.
- “Can you tell me about the last time you dealt with [the problem area]?”
- “What was the hardest part of that?”
- “What else have you tried to solve this?”
- “How are you dealing with this now?”
By focusing on past actions, you learn if the problem is a real, painful issue or just a minor annoyance. You discover if they have already invested time, money, or energy into solving it. If someone has already tried multiple workarounds, it’s a strong signal the problem is severe.
If they haven’t done anything, it’s a strong signal it’s not important enough to them, regardless of how much they compliment your idea.
“The most important thing is to get out and talk to your customers. Your initial idea is just a starting point.” — Paul Graham, Co-founder of Y Combinator
Beyond Words
After you’ve asked good questions and gathered facts about someone’s past behavior, you have valuable data. But data alone isn’t validation. The next, crucial step is to test that data with a request for a small, tangible commitment. This is the ultimate filter because compliments are free, but commitments have a cost — even a small one.
It’s the difference between what people say and what they do.
A useful conversation provides you with more than just interesting stories; it provides evidence. This evidence comes in the form of commitments that require the other person to give up a small amount of their own resources: their time, their reputation, or in a commercial context, their money.
Even the smallest commitment further validates the idea because it signals that the problem you’re discussing is painful enough for them to take action.
Here are the types of “currencies” you can ask for to test for a real signal:
- Time Commitment: This is the most common and accessible form of currency. Asking for a future, scheduled block of their time is a powerful test. A person who is merely being polite will hesitate to book a 30-minute meeting in two weeks, while someone who genuinely feels the pain of the problem will see it as a valuable use of their time.
- Reputation Commitment: Asking someone to vouch for you or your idea is a strong test of their belief. This could be an introduction to a manager, a key stakeholder, or other people who also experience the problem. By making an introduction, they are putting a small piece of their own social capital on the line.
- Resource Commitment: In a business context, this is often a pre-order or a deposit. But in a workplace or community project, it could be a commitment to provide data, to be the first to pilot a new process, or to volunteer their own effort.
If a person gives you compliments but is unwilling to offer any form of commitment, you may be dealing with a false positive — an interaction that appears interested on the surface but has no real intention of moving forward.
Pushing for a small, concrete commitment is the most effective way to distinguish these unproductive conversations from genuine opportunities for validation.
“People think focus means saying yes to the thing you’ve got to focus on. But that’s not what it means at all. It means saying no to the hundred other good ideas that there are.” — Steve Jobs, Co-founder of Apple
From Anecdotes to Patterns
A single, great conversation is a starting point, not a conclusion. The goal of validation is not just to collect individual stories, but to identify a consistent, repeatable pattern of problems within a specific group of people.
One person’s frustration might be an anecdote; the same frustration shared by ten people in similar roles is a strong signal of a real opportunity.
This is where the idea of segmentation becomes critical, even for non-commercial ideas. You need to ask yourself: “Who, specifically, am I trying to help?” The more clearly you can define this group, the more effective your validation process will be. For example:
- Instead of “office workers,” you might focus on “junior marketing associates at mid-sized tech companies.”
- Instead of “parents,” you might focus on “first-time parents of toddlers in my neighborhood.”
By narrowing your focus, you can start to test if the problems and behaviors you uncover are consistent. If you have five conversations with people from your target group and they all describe the same core problem and have tried similar workarounds, your confidence in the idea’s validity should skyrocket.
If their problems are all completely different, it’s a sign that your idea might be a solution in search of a problem, and you need to either refine your focus or reconsider the idea itself.
“We must learn what customers really want, not what they say they want or what we think they should want.” — Eric Ries, Author of The Lean Startup
Avoiding Common Traps
Knowing the rules is one thing; sticking to them under pressure is another. The validation process requires a high degree of discipline, and it’s easy to fall back into bad habits. Here are some of the most common traps to avoid:
Reverting to Pitching
The most common mistake is accidentally slipping back into explaining your idea. The moment you start talking about your solution, the conversation is no longer about their problem. You must consciously resist the urge to “save” a quiet moment by talking about your idea.
Accepting Compliments as Data
It feels good to hear someone praise your idea, but compliments are not evidence. When you receive one, your job is to politely deflect it and pivot back to a question about their life.
For example, if they say “That sounds amazing!”, you can respond with, “Thanks, I appreciate that. To help me figure out if it’s actually useful, can you tell me about the last time you…?”
Talking Too Much
A good validation conversation should feel more like an interview where you are the journalist. A good rule of thumb is that they should be talking 80% of the time. If you find yourself doing most of the talking, you are likely pitching, not learning.
Failing to Dig Deeper
The first answer someone gives is often a surface-level one. The real insights come from follow-up questions like “Why was that so frustrating?” or “What happened after that?” or “Can you tell me more about that?” Always probe for the underlying emotions and consequences of the problems they describe.
Having now established the importance of asking the right questions, listening for commitments, and staying disciplined, the next logical step is to ensure you can get these crucial conversations started in the first place.
Getting the Conversation Started
The way you initiate contact is critical to setting the right tone. You’re not asking for a favor or pitching a final product; you’re asking for their expert help. A powerful five-part framework can help you frame your initial request:
- Vision: State your broad ambition to solve a problem without mentioning your specific idea.
- Framing: Explain your current stage (e.g., “I’m in the early discovery phase”) and state clearly that you have nothing to sell or pitch.
- Weakness: Show vulnerability by mentioning a specific problem you’re stuck on.
- Pedestal: Acknowledge their expertise and explain why they, in particular, can help.
- Ask: Explicitly ask for their time.
This structured approach disarms the person, shifting the dynamic from a pitch to a genuine request for guidance, thereby increasing the likelihood of honest, unbiased feedback.
Conclusion: From Theory to Action
The principles for validating an idea offer a powerful framework for navigating the treacherous waters of feedback.
The core lessons are clear: shift the focus from your idea to their life, ask about specific past behaviors instead of future opinions, and push for tangible commitments to separate real interest from polite encouragement. By internalizing this mindset, we can stop collecting compliments and start gathering the hard-won truths that lead to meaningful, impactful solutions.
However, a framework is useless without action. The theory is the easy part; putting it into practice is what matters. To make this transition from reading to doing, two practical tools are provided below.

Meeting Planning: A 3-Step Process
Learning about a person is achieved in quick, focused and casual chats.
Before the Meeting
- Set Goals: Decide “What do I want to learn from these guys.” Write down (and share with your team, if you have one) 3 big learnable goals.
- Focus: Identify a specific group of people. Identify risks and roadblocks that are terrifying to ask about.
- Plan: Decide next steps and potential commitments. Decide if conversations are the right tool, and with whom.
- Prepare: Create best guesses about what the person cares about. Do a little research first if appropriate. No recordings or digital note-taking for a more natural feel.
During the Meeting
- Team Up: If possible, two people should attend: 1 to lead questioning, and 1 to take notes.
- Frame it: Refer to your goals, deflect questions about your idea, and ask the first question. Frame the conversation without mentioning your solution.
- Be Casual: Never have a formal interview.
- Take Notes: Take precise notes and underscore emotion with emojis ☆ :) :( :|
- Ask Good Questions: Nudge in useful directions. No hypotheticals or leading questions.
- Handle Compliments: Deflect compliments by never mentioning your solutions; instead, ask for the motivation behind their current process or past experiences.
- Dig Deeper: Dig beneath fluff (opinions, ideas, emotions) by asking about specific past events. Watch for fluffy adverbs: usually, always, never, would, will, might, could.
- Wrap Up: Finish as soon as the big 3 questions are answered. Press for commitments and next steps.
After the Meeting
- Review: Review notes with your team. Immediately transcribe notes to a shared, searchable space.
- Follow Up: Schedule follow-ups.
- Analyze: Review commitments made for next steps. Decide on the next 3 big questions.
- Validate: Identify problems that matter by the time & effort people actually spent dealing with them. If they haven’t tried to find a workaround, the problem may not be severe.
