In our previous lesson on Wiio's Law, we operated on the defensive principle that communication is inherently prone to accidental failure. We developed strategies to mitigate the damage from these inevitable misunderstandings. Today, we shift from defense to offense. We will explore how to deliberately introduce a controlled error to provoke a precise, corrective response from another person.
This brings us to Cunningham's Law, which famously states: "The best way to get the right answer on the internet is not to ask a question, but to post the wrong answer." At its heart, this law leverages a powerful psychological impulse: the near-irresistible urge to correct someone who is wrong, especially about a topic we care about. Your objective for this lesson is to apply this principle as a sophisticated elicitation technique, using it to draw out correct sizing information from a client and to help a partner articulate a vague relationship boundary with precision.
The Art of Strategic Error: Elicitation Techniques
Cunningham's Law is more than just a wry observation about internet forums; it's a practical tool for information elicitation. When direct questions fail—because the other person is uncertain, unwilling, or unable to articulate an answer—providing a "wrong" answer gives them a fixed point to push against. It lowers the cognitive burden from generating a new answer to simply correcting an existing one.
This is a well-understood technique in fields requiring subtle information gathering, such as business analysis and negotiation. The following resource outlines several such conversational methods.

This document provides a concise menu of techniques used by FBI agents and business analysts to draw out information without asking direct questions. We will focus on the methods that are direct applications or close cousins of Cunningham's Law.
Please read the following three techniques from the list: First, the most direct application: Deliberate False Statements. Note its strength in confirming facts. Second, a slightly more confrontational variant: Criticism. This works by provoking a defensive reaction, which is often detailed and passionate. Third, a method for exploring justifications: Opposition. By playing devil's advocate, you invite the other person to elaborate on their reasoning.
These techniques all pivot on the same principle: a carefully crafted incorrect statement is often more generative than an open-ended question.
Application 1: Eliciting a Precise Bra Fit
Scenario: You are fitting a new client for a complex, custom-designed bikini top. She is wearing a heavily padded bra, which distorts her natural shape, and she seems unsure of her own size. Your direct questions like "Does that feel right?" are met with vague, unhelpful answers like "I guess so." You need concrete information to proceed.
Analysis:
The client's vagueness isn't necessarily uncooperative; she may lack the specialized vocabulary to describe fit issues, or she may be hesitant to contradict an expert. Asking her to generate a precise answer ("Where exactly is the pressure?") puts the full analytical burden on her. Cunningham's Law allows you to shoulder that burden and present her with a simple binary choice: agree or correct.
Applying Cunningham's Law (Strategic Misstatement):
-
To Determine Band Size: You take a measurement over her padded bra, knowing it will be inaccurate. The tape reads 35 inches. Instead of asking what her size is, you make a deliberate false statement.
- You: "Okay, based on this, we'll start with a 36 band."
- Client: "Oh, no, a 36 is always too loose on me. I'm a 34 in almost every brand. Sometimes a 32 if it runs large."
- Outcome: You have just elicited a rich data point: her experienced size range and how she perceives different brands' sizing. This is far more useful than the "35 inches" you measured.
-
To Diagnose Cup Fit: You put her in a sample size that you suspect is slightly too small. You observe the initial signs of "quad-boob" (spillage over the top of the cup), but instead of pointing it out, you mislabel the problem.
- You: "It seems like we have a little bit of gaping at the top of the cup here."
- Client: "Gaping? No, not at all. Actually, I feel like I'm spilling out right here on the side."
- Outcome: By presenting her with the opposite of the actual problem, you prompted her to correct you with the precise location and nature of the fit issue. You now have actionable information to adjust the pattern.
This technique is known in negotiation circles as "mislabeling." It gives the other person the opportunity to correct you, and in doing so, they reveal critical information.

Former FBI hostage negotiator Chris Voss explains how to use intentional mislabeling to prompt correction and gain information. This reframes Cunningham's Law as a powerful tool for guided discovery.
First, read the paragraph explaining the concept of mislabeling. Notice how it creates an opportunity for the other side to correct you and reveal what's really on their mind. Then, review the glossary definition to solidify the concept.
Application 2: Eliciting a Clear Relationship Boundary
Scenario: We return to the Vee relationship from our last lesson. The wife (W) has told her husband (H) she needs "more space" regarding her relationship with her lover (L). The husband, wanting to be supportive, is left confused by this vague term. A direct question like "What do you mean by 'space'?" might feel demanding and put her on the defensive.
Analysis:
The wife may not have a pre-formulated, precise definition of "space." The feeling is real, but the rules are not yet defined. Using Cunningham's Law, the husband can propose an imperfect summary—a "wrong" version of the rule—to prompt her to articulate the right one.
Applying Cunningham's Law (Imperfect Summary):
Instead of asking for a definition, the husband offers a plausible but incorrect interpretation of her request.
- Husband: "Okay, I'm hearing that you need more space, and I want to make sure I get that right. It sounds like you're saying you'd prefer we don't talk about L at all anymore, and that I should just pretend that part of your life doesn't exist. Is that what you mean?"
This statement is deliberately, but gently, wrong. It's an over-correction that invites her to scale it back to what she actually wants.
Expected Result:
This phrasing is unlikely to be met with a simple "yes." The wife's instinct will be to correct the inaccuracies in his summary.
- Wife: "No, that's not it! I'm not asking you to pretend he doesn't exist. That would be weird. It's more that when I get home from a date, I don't want to feel like I have to give you a full report immediately. I need some time to process it myself. Maybe we can agree that I'll be the one to bring it up the next day, when I'm ready."
Outcome:
Success. By offering a wrong answer, the husband prompted his wife to replace the abstract concept ("space") with a concrete, behavioral protocol ("I will initiate the conversation the day after a date"). He didn't demand a definition; he elicited one. He now has a clear, actionable rule to follow, preventing the kind of misunderstanding we analyzed in our lesson on Wiio's Law.
Conclusion
Cunningham's Law is a potent tool for any analyst or communicator. It demonstrates that sometimes the most effective way to get a clear signal is to deliberately introduce a little noise. By mastering the art of the strategic error, you can guide conversations, elicit precise information, and clarify ambiguity without appearing confrontational.
Key Takeaways:
- Leverage the Impulse to Correct: Cunningham's Law works because people have a strong cognitive and social drive to correct inaccuracies, especially in areas where they have expertise or emotional investment.
- Be Strategically Wrong: The key is not just to be wrong, but to be wrong in a way that invites a specific correction. Your "wrong answer" should be a plausible misinterpretation that the other person feels compelled to refine.
- From Vague to Concrete: This technique is especially powerful for moving a conversation from abstract concepts (like "fit" or "space") to concrete, actionable details (like "spillage on the side" or "let me initiate the talk the next day").
In our next lesson, we will continue exploring principles of robust communication by examining Postel's Law, also known as the Robustness Principle: "Be conservative in what you send, be liberal in what you accept." This will shift our focus from eliciting information to designing systems—whether in code or in relationships—that can gracefully handle the imperfect and often unpredictable inputs from others.
