Let’s get one thing straight: that world-changing idea keeping you up at night is statistically a dud. Your mom loves it, your friends say it’s “cool,” and none of them will ever pay you a dime for it. They’re being polite. The market isn’t.
The only way to know if you’re sitting on a goldmine or a dumpster fire is to stop pitching your vision and start trying to kill your idea with brutally honest concept test questions. This isn’t about stroking your ego. It’s about killing your bad ideas before they kill your bank account.
Your 'Genius' Idea Is Probably Worthless

I see it constantly. Founders coddle their ideas like precious newborns, shielding them from reality. They ask leading questions like, "Don't you think this is a cool feature?" They get pumped when their buddies say they'd "totally use it," mistaking politeness for purchase orders. Then they launch to crickets and wonder what went wrong.
A painful truth now is infinitely cheaper than a catastrophic failure later. Ignore your customers, and you’ll be lucky to survive the quarter.
Concept testing isn't the same as broad questions for market research. This is a focused interrogation of one specific idea. Your job isn’t to get a “yes.” Your job is to understand the “why” behind the “hell no.” Does this solve a hair-on-fire problem, or is it a mild inconvenience people are fine ignoring?
Takeaway: Stop trying to prove your idea is good and start trying to prove it's bad. If you can't, you might actually have something.
Why Your Questions Are Giving You Garbage Data
If you're asking, "Would you use this?" or "Do you like my idea?" you're not gathering data—you're fishing for compliments. Stop it. People are hardwired to be agreeable, especially when you’re looking at them with those hopeful founder eyes. They’ll nod, say yes, and immediately forget you exist.
The problem is you're asking about a hypothetical future. Humans are terrible at predicting their own behavior. We all imagine a better version of ourselves who would absolutely use your app. The real us is a creature of habit who hates change.
To get real answers, anchor your concept test questions in past behavior. The past is concrete—a verifiable record of pain, workarounds, and money already spent.
Ditch the Crystal Ball, Grab a Shovel
Think of yourself as an archaeologist, not a fortune-teller. Dig up hard evidence of the problem.
Weak Question: "Would you pay $20 a month for this?" (Costs them nothing to agree.)
Killer Question: "What are you using to solve this right now, and what does it cost you in time or money?" (Grounds the answer in reality. If they're not spending anything now, they won't start with you.)
Weak Question: "Do you like this new feature?" (Invites vague opinions.)
Killer Question: "Tell me about the last time you dealt with this. What did your process look like?" (Prompts a story about a real event, revealing their actual frustrations.)
A "yes" to a hypothetical question feels great for five seconds. A detailed story about a past struggle is the raw material for a product people will actually buy. Even McDonald's, before launching all-day breakfast, ran massive tests showing 40–50% of customers would visit more often based on existing habits. That led to a 5.7% sales jump.

Takeaway: Stop asking about the future and start interrogating the past—it’s the only place the truth is buried.
Crafting Questions That Expose True Purchase Intent
Let's talk about the only thing that keeps the lights on: money. Purchase intent is the razor-thin line between a business and an expensive hobby. You can't just ask, "So, would you buy this?" It’s a coward's question, and the answer is worthless. People love spending hypothetical money.
Your job is to become a detective interrogating a suspect for cold, hard facts. This means crafting concept test questions so precise they separate tire-kickers from actual buyers. A good primer is learning how to write open-ended questions that force people to think instead of just nodding.
Pricing Questions That Reveal True Value
Never ask "How much would you pay for this?" directly. You'll get a number plucked from thin air. Instead, triangulate their perception of value with questions that force a trade-off.
- The Van Gorp Method: Name a price that’s a little too high. If they flinch, fine. But if they hesitate, follow up with, "What would need to be included for this price to feel like a steal?" Their answer is your feature roadmap.
- Comparative Probing: Ask, "What are you currently paying to solve this?" If the answer is "nothing," you have a much harder sell. If they're paying a competitor, you've just found your price anchor.
These approaches force a real conversation about value. The goal of pricing questions isn't to find a price. It's to uncover the pain. The more painful the problem, the more flexible the price.
Uniqueness and Relevance Questions
Even if they say they’d buy it, you need to know why. Is your concept truly unique, or is it just a shinier version of something else? A product without a clear "why" is a commodity, and you’ll lose a race to the bottom on price.
Ask questions that ruthlessly test your differentiation:
- The "Magic Wand" Question: "If you could wave a magic wand and change anything about how you [solve the problem] right now, what would it be?" This uncovers their deepest frustrations with existing solutions.
- The "WTF" Test: After showing them the concept, ask, "What, if anything, stood out to you as being completely new or different?" If they can't name a thing, your unique selling proposition is a delusion.

Feel-good questions are a direct pipeline to garbage data that will mislead your entire strategy. If you want to see how this logic applies to automated systems, learn how to build a chatbot for lead generation that converts.
Weak vs. Killer Concept Test Questions
| Garbage Question (What You're Probably Asking) | Killer Question (What You Should Be Asking) | Why It Works |
|---|---|---|
| "Do you like this idea?" | "What is your immediate, gut reaction to this?" | Bypasses politeness for an unfiltered first impression. |
| "Would you buy this?" | "Under what circumstances could you see yourself using this?" | Grounds the answer in a real-world context, revealing actual use cases. |
| "How much would you pay?" | "What would need to be true for this to feel like a great value at $99?" | Frames price as a function of value, uncovering missing features. |
| "Is this feature useful?" | "Walk me through how this feature would fit into your day." | Forces them to visualize usage, exposing practical value (or lack thereof). |
| "What do you like most?" | "If you had to describe this to a friend, what would you say?" | Reveals what's most memorable and compelling in their own words. |
Takeaway: Stop asking if people will buy and start asking questions that prove they can't live without it.
How Your Test Setup Can Invalidate Your Results
You can write brilliant concept test questions, but if your setup is flawed, your data is garbage. It's like running an experiment in a dirty lab.
Your audience isn't your mom. Asking family, friends, or a random panel is a waste of time. Your audience needs to be a sniper shot, not a shotgun blast. Find people who are currently feeling the pain. Target "demand gen managers at B2B SaaS companies with 50-200 employees," not just "marketers." Go to their watering holes—niche subreddits, LinkedIn groups, industry Slacks. Filter ruthlessly.
Here’s a truth that feels backward: your concept should be a little bit ugly. The moment you show a pixel-perfect mockup, they become an art critic, not a problem-solver. Feedback turns to button colors and fonts. A low-fidelity wireframe or a simple text description forces the conversation to stay on the concept. You're not here to show off your UI skills; you're here to find out if your business has a pulse. Using methodologies like multivariate testing can also ensure one slick design element doesn't overpower the core concept.
Takeaway: Test with a scalpel, not a sledgehammer, and present a sketch, not a masterpiece.
How to Analyze Feedback Without Lying to Yourself
The results are in. Now for the hardest part: looking at the data without telling yourself a story you want to hear. Founders are masters of self-deception. We see a 30% positive response as a "promising signal" while ignoring the feedback that guts our core assumptions.
Triage the feedback like a battlefield medic. Tag every raw comment: Pain Points, "Aha!" Moments, Confusion, and Indifference. Indifference is a silent killer. Anger or confusion means they care enough to react. A "meh" is a death sentence. It means your idea is a vitamin, not a painkiller. If you have to squint to see the value in your feedback, the market won't even bother opening its eyes.
Not all feedback is equal. A "no" from outside your ideal customer profile (ICP) is noise. A "no" from your perfect target user is a five-alarm fire. Segment the data by role, company size, and past behavior. You might find your concept scored a dismal 4/10 overall but a 9/10 with restaurant owners. Congratulations, you just found your actual market. This isn’t cherry-picking; it’s finding the small pocket of rabid fans who will become your first champions. Our guide on how to analyze survey data has a more structured approach.
The only way to avoid lying to yourself is to set kill-or-pivot signals before you see the results. For example: Kill if <20% of our ICP shows strong purchase intent. Pivot if >50% are confused by the core value prop. Go if >40% ask, "When can I use this?" Write them down. This takes emotion out of the equation.
Takeaway: Stop looking for validation and start looking for a verdict—the market is the judge, jury, and executioner.
Your Only Next Step
This all boils down to one thing: not wasting your time, money, and sanity building something nobody wants. Well-crafted concept test questions are your cheapest insurance policy against launching to an empty stadium.
You can learn this the easy way by asking hard questions now, or the hard way after you've burned through your runway. Your idea isn't precious until the market proves it is. The market is indifferent to your passion. It only cares if you solve a real, painful problem. It's time to stop talking about your brilliant idea and start actively trying to kill it. If it survives, you might just have a business.

We Get These Questions All The Time
Let's cut through the noise. Here are the questions I get asked constantly.
How Many People Do I Actually Need for a Concept Test?
Early stage? 5 to 10 in-depth interviews with your perfect customer. You need qualitative gold, not a giant sample size. Once you've refined the concept based on that, go for 50 to 100 high-quality survey responses to validate it quantitatively. Anything more is overkill at the start.
What’s the Single Biggest Mistake People Make When Writing Questions?
Asking leading or hypothetical questions. Anything starting with "Would you..." or "Could you imagine..." is garbage. It asks people to predict the future, and they can't. Instead, anchor them in the past: "Tell me about the last time you tried to solve [problem X]." This forces a story about a real experience, which is the only data that matters.
Should I Offer an Incentive for Participation?
It’s a double-edged sword.
- In-depth interviews: Yes. Their time is valuable. A gift card shows you respect it.
- Quantitative surveys: Be careful. You'll attract "survey mercenaries" who just want the cash. If you must, do a raffle for a larger prize instead of a small payout for everyone.
Honestly, the best participants are intrinsically motivated because they want a solution to exist. Their feedback is worth 10x more than someone you paid $5.
