The curse of knowledge: When you don't sell because you know too much.

The Curse of Knowledge: How Simple Language Increases Sales

Have you ever spoken to a customer and seen growing incomprehension in his eyes?

This is the Curse of Knowledge - a trap that sellers, marketers and experts fall into. Paradoxically, the more you know about your product, industry or technology, the more difficult it is to convince others to trust and buy you.

The curse of knowledge is such a common problem that most people don't notice it. This is a shame because it causes a lot of frustration and failure in both sales and marketing.

In this article you will learn:

  • What exactly is the Curse of Knowledge and where does it come from?

  • Why it's destroying sales and marketing.

  • How to recognize it in practice.

  • What are the ways to overcome it and speak the customer's language?

What is the Curse of Knowledge?

The Curse of Knowledge is a psychological phenomenon in which a person with extensive knowledge in a given area is unable to put himself in the role of someone who does not have this knowledge.

The result is the use of difficult language, mental shortcuts and messages that are incomprehensible to customers. Something seems obvious to an expert that is completely new to others.

As they say in Poland: "the ox forgot what a calf it was."

In such a situation, having knowledge and skills harms instead of helping - although this seems paradoxical.

Where does the Curse of Knowledge come from?

The curse of knowledge is usually caused by:

  1. staying only among specialists - you adopt their way of thinking, vocabulary and mental shortcuts.

  2. projecting your perspective onto the customer - you start to think that if you perceive the world in a certain way, everyone else does too.

  3. lack of honest communication - the client will rarely admit that he does not understand something, because it harms his self-esteem. When you try to show off your professionalism, many people can feel overwhelmed and discouraged. They will agree with you even though they understand half or even less.

  4. laziness – it's easier to speak slang than to translate. Thinking professionally and translating it into simple language at the same time is hard work. Not everyone wants to be a teacher for their clients.

  5. ego - some experts believe that simplification undermines their professionalism.

It's always worth remembering that your client is not you or your industry friend. The client spends his time learning other things, he has his own activities, his own problems. He won't spend hours learning just to understand your industry, professional lingo. If he came to you for help, it means that he is not a specialist in your field - if he were, he would solve his problem himself.

Why does the Curse of Knowledge corrupt sales and marketing?

In one sentence: it discourages customers at every stage of contact with your brand.

Someone with the curse of knowledge may:

  • cause misunderstandings and frustration

  • spoil the negotiations

  • generate an advertising message that reaches no one.

  • what's worse: you may start creating services and products that no longer meet the needs of customers - so what if you are a chef after 10 schools and make the best foie gras in the country, if customers in your area simply prefer pizza?

Simple examples of the Curse of Knowledge

I am sure that each of us has experienced a similar situation:
  • SaaS – explains about "hybrid clouds" when the customer only wants to know whether his data is safe.
  • Bank - advertises "escrow account" while the customer asks: "is my money protected?"
  • The doctor talks about "hypokalemia and tachyarrhythmia" instead of telling the patient: "you lack potassium and that's why your heart beats faster."
  • The architect - presents the "ergonomics of the functional layout", and the client simply wanted to know: "will the sofa fit in the living room?"

How to fight the Curse of Knowledge?

The good news: you can beat it.

  1. Listen to your customers. Preferably those who know nothing about your industry. The more ignorant you are about a given topic, the better. Their questions and misunderstanding are worth their weight in gold.

  2. Test your messages on people outside your industry. Family, friends, testers - if they don't understand something, your customers won't understand it either. Test and change the message until you succeed.

  3. Teach in plain language. If the topic requires professionalism that cannot be reduced, use an accessible form of education:

    - short video,

    - blog article [LINK: blog],

    - customer training.

  4. Use content marketing. The questions that arise in conversations with clients are ready-made ideas for materials: articles, webinars, videos.

For those curious: what do world-class detectives learn?

Writer William C. Taylor calls it The Paradox of Expertise: the longer you look at something from the same perspective, the harder it is to see new possibilities and patterns.

Amy E. Herman, a lawyer and art historian, created the program The Art of Perception. He takes policemen, FBI and CIA agents to art museums - to Picasso, Caravaggio, Hopper.

“The exercise is not about looking at art, but about talking about what you see. Or, very often, what you don't see. Time and time again, experienced observers miss key elements of an image that convey an important message, miss clues in a scene about what's happening, or simply fail to describe what's right in front of them. Thanks to these activities, they are no longer afraid to change their perspectives. – explains Herman.

Participants are not allowed to use the words "of course" and "sure" or to point at an image to describe an element of it. Instead, they must verbally present their observations to their peers.

Effect? They learn to change their perspective and then better analyze evidence and situations at work.

Amy Herman's seminar is an elegant way to break the routine and a warning that even the most outstanding specialists can stop noticing the obvious. It's just a simple game of art, but it sharpens your skills and clears your mind. "In New York, we consider the extraordinary to be ordinary, so during training we always try to be even more aware as observers.” – explained the deputy chief in one of many enthusiastic opinions about the program.

Checklist: 5 questions to help you check whether you have fallen into the Curse of Knowledge

  1. Can I explain my product or service in 30 seconds to someone outside the industry?

  2. Does the customer understand my advertising slogan without additional explanations?

  3. Are there more features than benefits in my marketing materials?

  4. Do I test my message on people who don't know my industry?

  5. Has a client ever said, “It's too complicated for me”?

If you answered "yes" to at least one question, it means that the Curse of Knowledge also works for you.

The most common mistakes resulting from the Curse of Knowledge

  • Overloading the presentation - too much technical data, too little specificity for the client.

  • Talking about features instead of benefits - "our system has 12 modules" instead of "you will gain 30% more time".

  • Using industry jargon in advertising - slogans that are understandable only to specialists.

  • Assuming that the client will "understand" anyway - lack of simple examples and analogies.

  • Demonstrating professionalism - communication that, instead of building trust, intimidates and distances you.

Summary

The Curse of Knowledge and the Paradox Expert opinions show that it is most difficult to speak simply about what we know best. If a customer doesn't understand your message, they won't buy - no matter how good the product is.

There is a nice saying for this: “If you can't explain something simply, it means you don't fully understand it.”

Therefore, it is worth asking: – Does the client really understand what I am saying to him? – Do I really see what is in front of my eyes?

Because simple language and a change of perspective often sell more than the most sophisticated professionalism.

FAQ – frequently asked questions about the Curse of Knowledge

What is the Curse of Knowledge in business?

The Curse of Knowledge is a phenomenon in which an expert forgets that his interlocutor does not have the same knowledge or experience. In practice, this manifests itself in the use of complicated language, industry abbreviations or technical jargon. Instead of feeling confident and understood, the client begins to get lost. This not only makes sales difficult, but also weakens trust - because no one likes to feel less competent. In business, the effects of the Curse of Knowledge can be particularly painful: from failed negotiations to the loss of customers who will choose the competition's simpler and clearer solution.

Why is the Curse of Knowledge dangerous in sales?

Sales are based on relationships and a clear message of values. If a customer doesn't understand your offer, they won't buy - even if your product is the best on the market. Curse of Knowledge:

  • discourages customers already at the stage of the first conversation,

  • spoils negotiations because the parties do not speak the same language,

  • causes marketing campaigns to fall on deaf ears,

  • leads to the creation of services detached from the needs of the market. Imagine a chef who advertises his "foie gras with port reduction", while his customers simply want good pizza.

How to recognize the Curse of Knowledge in yourself?

Here are some warning signs:

  • Customers often ask for additional explanations.

  • People are silent instead of asking questions - which means they don't understand, but they don't want to admit it.

  • Customers nod unenthusiastically - they say "aha, sure", even though in reality they didn't understand much.

  • Marketing materials sound smart, but they do not trigger a reaction or conversion. It is also worth asking yourself: can I explain my offer in 2-3 simple sentences to a person who knows nothing about it? If not, it's a sign that the Curse of Knowledge is working.

Is it possible to completely avoid the Curse of Knowledge?

It cannot be eliminated 100%, because each expert develops and over time it becomes more and more difficult for him to see through the eyes of a novice. However, it can be effectively controlled. How?

  • Test the message on people from outside the industry.

  • Listen to your customers – their questions and misunderstandings are the best feedback.

  • Use simple language – talk about benefits, not features.

  • Create educational materials – articles, videos, webinars help explain difficult topics step by step.

  • Practice changing your perspective – for example, by describing your offer as if you were explaining it to a child or a friend from outside the industry.

Thanks to these practices, the Curse of Knowledge ceases to be an obstacle and becomes a tool for building a simple and effective message.

What are some examples of the Curse of Knowledge in sales and marketing?

There is no shortage of examples:

  • A SaaS vendor tells a customer about a "hybrid cloud architecture" when the customer only wants to know if their data is safe.

  • The bank advertises an "escrow account" instead of saying directly: "Your money is protected."

  • The doctor talks about "tachyarrhythmia" instead of explaining: "you lack potassium and that's why your heart beats faster."

  • The architect talks about "ergonomics of the functional layout", instead of simply checking whether the sofa will fit in the living room. Each of these examples shows that the lack of simplicity blocks the purchase decision.

How to avoid the Curse of Knowledge in marketing materials?

It is best to use the "customer language" principle:

  1. Instead of features -> show benefits.

  2. Avoid industry-specific abbreviations and technology names unless you really need them.

  3. Create content in different formats – videos, infographics, blogs – because different people learn differently.

  4. Test the message - show your advertising slogan to someone from outside the industry and check if they understand it. This approach means that marketing stops being art for art's sake and starts working for sales.
