In this module
Using the Shannon-Weaver model of communication, a sales story from the early days of Apple Computer, and a caseworker's meeting with a man seeking housing help, this module shows how easily a well-intended message gets distorted along the way. You will learn four simple practices—ask, listen, check, and adjust—that help our help truly help.
Key ideas
- We often overestimate how well we understand one another; a message is not complete when we send it, but when it has been heard, understood, checked, and clarified.
- In the Shannon-Weaver model, noise is anything that distorts a message, and in human conversation the most powerful noise is often invisible: differences in culture, environment, education, life experience, stress, fear, or expectation.
- Tone of voice, facial expression, and posture can strengthen or undermine our words, and people who have spent years being judged or dismissed notice the difference.
- Before offering a solution, we can ask, listen, check what we heard, and adjust our words, tone, pace, or approach; that is not weakness but respect, and respect is often the beginning of trust.
- We can do the right thing the wrong way; communicating with humility, patience, curiosity, and respect is where real help begins.

Welcome to Module 5 of Engaging Poverty 101: The Conversation. When what we say is not always what another person hears—and how that shapes our efforts to fight poverty.
While we have all heard of pyramids promising exact learning percentages for reading, hearing, seeing, and retaining, those numbers lack evidence. Memory just doesn’t work through a simple fixed formula as those pyramids suggest. In fact, every message we distorting the message to varying degrees – some that are so extreme the entire message is lost in translation. Research does tell us, however, that we often overestimate how well we understand one another. While the message we deliver is clear to us, it is not as clear to the person receiving it. That is why, if we want to communicate effectively, we must learn to ask, listen, check for understanding, and be willing to adjust. And that matters because clear, respectful communication reduces confusion, builds trust, and makes collaboration more likely—while poor communication can cause people to feel dismissed, judged, or blamed—even when that was not the intent.
And clear communication produces better information, better relationships, and better coordinated action. It helps businesses execute, helps couples repair, helps communities cooperate, gives countries alternatives to escalation, and can reduce preventable barriers to support systems that people in poverty need to survive and build stability, which makes it important to our discussion, particularly since most of us think we communicate better than we actually do.
The Shannon-Weaver Model
In 1948, Claude Shannon introduced a mathematical theory of communication. It began as an engineering problem: how to measure information and protect a telephone or radio signal from distortion as it travels through a channel. Shannon was not originally trying to explain human conversation – just solve a problem in communication signals. But in 1949, Warren Weaver helped make the framework accessible to a broader audience, because the insight behind Shannon’s work also applies to human conversation: before a message can be understood between two people, it has to survive the noise between the sender of the message and the receiver. Words, tone, and body language are sent through a channel to a receiver, who decodes and interprets them based on how much or how little of the message they can actually see, hear, or perceive – along with other influences that he called the noise – anything that distorts the message. This is why even a well-intended message can be received in a way the sender never intended.
As they first did, we usually think of noise as something literal: a poor phone connection, a crowd, a siren, a broken microphone. But in human conversation, the most powerful noise is often invisible. It can be the distortion created by differences in culture, environment, education, life experience, stress, fear, or expectation.
The sender thinks, I was perfectly clear. But the receiver hears something entirely different. And neither person may realize it happened.
The message is not complete when we send it. It is complete when it has been heard, understood, checked, and clarified.
“Clarifying can feel uncomfortable—even as though our intelligence is being questioned. But when clarity matters, skipping that step may leave someone with a message we never intended. It takes extra time, but if we’re serious about communication, it’s time well spent.”
A Personal Example: Apple Computer
Let me give you a personal example of noise.
I worked in sales for Apple Computer in the 1980s, when personal computers were just beginning to find their way into homes and offices. At that time, computer jargon belonged almost entirely to people inside the industry. Everyday people — and even many business people — had very little frame of reference for it.
Take the word byte. To most people, that was something you did with a sandwich. Bits were simply “a bit of this” or “a bit of that,” not a unit of computer information.
If I used the term ‘ram,’ someone might have thought of one car hitting another. Someone else might have pictured a Dodge pickup. ROM sounded like somebody’s initials or the acronym for Range of motion.
If I walked into a sales call and started throwing those terms around without explanation, I had already lost the conversation. The noise — in that case, the gap in education and experience — was so significant that the message never arrived. I had to recognize the noise and adjust my language before I could sell anything.
But the noise also ran in the other direction.
People with deep experience in large-scale computing could look at the limited memory and processing power of early personal computers and wonder why anyone would care. The idea that a small machine could be useful in a home, classroom, or ordinary office did not fit the assumptions formed by their experience with much larger systems.
That is not necessarily arrogance. It is noise. Their experience shaped what they expected a computer to be, just as a new customer’s lack of experience shaped what they could understand.
The personal-computing market grew rapidly in the early 1980s because people eventually learned to see a computer as something more than a large institutional machine. The important point is this: the same message can meet two completely different audiences and be distorted in two completely different ways.
The Noise of Tone and Body Language
Another kind of noise has nothing to do with vocabulary, education, or experience. It is the tone of our voice, the expression on our face, and the posture we bring into a conversation.
Have you ever said the right thing the wrong way?
Maybe the words were meant to be helpful, but your tone sounded impatient. Maybe you offered assistance, but your crossed arms, lack of eye contact, or hurried voice communicated something else entirely. The listener may not remember every word you used, but the interaction can leave a lasting impression about whether they felt respected, rushed, or dismissed.
Our words can send one message while our tone and body language send another. When those messages do not match, people notice the inconsistency. They may begin to wonder: Do you really mean what you are saying? Do you respect me? Are you listening — or are you trying to get rid of me?
This matters deeply when we work with people in poverty. Many have spent years being judged, dismissed, talked down to, or treated as a problem to be solved. They are overly sensitive. A well-intended sentence can be heard as criticism when it is delivered with impatience, superiority, or frustration.
Our nonverbal communication does not replace our words, but it can strengthen them or undermine them. A calm voice, open posture, eye contact, patience, and genuine curiosity can communicate dignity before we ever offer a solution.
A Caseworker and a Client
Imagine a caseworker sitting across from a man who has come in to ask for help with housing assistance. The caseworker says:
“I’m here to help. Tell me your situation.”
While the words are accurate, her shoulders are turned away and her voice is flat — the voice of someone who has said the sentence a hundred times today and is already thinking about the next case.
The man hears the words. But he may receive a different message:
You are an interruption. You are one of many. I am not really here. I do not really care about you; I am just doing my job.
The caseworker may not mean any of that. She may not even realize what her body language has communicated. But something in him feels the separation. He offers shorter answers. He leaves out details that could help her understand. He walks out feeling the same way he felt when he walked in — invisible.
Now reverse it.
Same words. Same form. But this time the caseworker pauses, turns her chair toward him, makes eye contact, and leans forward slightly. Her voice slows down enough to communicate: I have time to hear you. She may begin with a human moment — not an interrogation, but a real conversation about something in her own situation, something more personal than being matter-of-fact.
The practical task has not changed. But the noise has been reduced. And the conversation that follows can be completely different.
That is the power of body language as noise. The words may not change, but the experience does. When we pause to consider our own interactions, we recognize that all of us—not only those we hope to help—want to be heard, understood, and treated with dignity.
Reducing the Noise
If we want to communicate effectively, we must learn to reduce the noise. That means taking into account the other person’s culture, education, experience in a particular area, age, environment, and current circumstances.
If we fail to do that, we can come across as though we are somehow above them — someone whose time is limited, whose answers are already formed, and who does not truly care enough to understand. Even when we genuinely want to help, our communication can send the opposite message.
And when that happens, the conversation becomes about us — our knowledge, our schedule, our solution, and our comfort — rather than about the person in front of us. Many of us are so busy pointing out the flaws in others, we forget about the relationship we may be sabotaging in order to get our way. That doesn’t mean correction isn’t important, it simply means the way we go about it may be even more important than the correction itself.
Effective communication begins when we make the effort to understand their world before expecting them to understand ours.
So let us make this practical. Before we offer a solution, we can do four simple things:
Ask. Do not assume you already understand.
Listen. Give the person room to tell the story in their own words.
Check. Repeat back what you believe you heard and ask whether you have it right.
Adjust. If the message is not landing, change the words, tone, pace, or approach.
That is not weakness. That is respect. And respect is often the beginning of trust.
In the Shannon-Weaver model, reducing noise makes it more likely that the message we intend is the message another person actually receives. In the real world, it makes it more likely that our help will truly help.
Closing
We can do the right thing the wrong way. Sometimes, even our help can hurt.
But when we learn to communicate with humility, patience, curiosity, and respect, we make room for trust. We become less interested in being the person with the answer and more interested in being the person who truly understands the question.
And that is where real help begins.
Transition to Module 6
Now we understand that communication is essential. It can open doors, build trust, and help us understand the person in front of us. But even the best conversation cannot remove every obstacle.
Something else looms over families experiencing poverty: the housing crisis. When rent takes too much of a paycheck, when a safe home is out of reach, or when one setback can lead to eviction, every part of life becomes more difficult—work, school, health, parenting, and hope itself.
Affordable housing is not the only issue in poverty. But it is one of the most concrete and consequential barriers to stability. It is to that topic we now turn in Module 6: The Affordable Housing Crisis.
I hope you will join us.
