Most conversations are guided by invisible expectations. We expect people to stand a certain distance away, respond within a reasonable time, use a respectful tone, keep their promises, and act in ways that fit the relationship. When those expectations are met, we often move through the conversation without thinking much about them. When they are broken, we notice.
Imagine sending an important message to someone you trust. You know they are busy, but they usually respond within a few hours. This time, a full day passes. Then another. The message still shows as read.
At first, you try to be reasonable. Maybe they forgot. Maybe something came up. But slowly, the silence starts collecting meaning. You wonder if they are upset, avoiding you, or no longer interested in the relationship. What changed was not only the delay. What changed was that the delay violated what you expected from that person.
That is the heart of expectancy violations theory. Developed by communication scholar Judee Burgoon, the theory explains how people respond when someone’s behavior breaks an expectation. For academically inclined readers, Burgoon’s overview of expectancy violations theory explains how unexpected behavior can affect attraction, credibility, persuasion, and interaction outcomes.
A simple story
Two friends, Collins and Kossi, had known each other for years. Kossi was the steady one. He remembered birthdays, followed through on plans, and usually answered messages quickly. Collins trusted that pattern.
One week, Collins asked Kossi for help reviewing a proposal. Kossi said, “Send it over. I’ll look at it tonight.”
Collins sent it. No response came that night. The next morning, still nothing. By the afternoon, Collins felt irritated. By evening, he felt embarrassed that he had asked.
When Kossi finally replied two days later, he wrote, “Sorry. Got busy. Looks fine.”
The words were small, but the impact was not. Collins did not only hear a late response. He heard a violation of reliability. In his mind, Kossi had always been dependable, and that is why the delay felt larger than it might have from someone else.
This is one of the important lessons of expectancy violations theory: the meaning of unexpected behavior depends partly on who does it. If an unreliable person replies late, we may shrug. If a reliable person replies late, we may wonder what went wrong.
Violations can be positive or negative
Not every violation is bad. Sometimes people surprise us in ways that improve the relationship.
A quiet coworker speaks up in a meeting and offers the clearest solution in the room. A reserved friend sends a deeply thoughtful note. A manager who rarely gives praise stops to recognize someone’s effort. A teenager who usually avoids family conversation sits down and talks honestly.
These moments violate expectations, but in a positive way. They can increase respect, warmth, trust, or closeness because the unexpected behavior is better than what we predicted.
Negative violations work differently. A trusted person breaks a promise. A polite person speaks harshly. A leader who claims to value transparency hides important information. A friend who usually listens suddenly dismisses what matters to you.
In both cases, the unexpected behavior makes us pay attention. We begin asking, “What does this mean?”
That question matters because people rarely respond only to the behavior itself. They respond to the meaning they attach to it.
Context changes the violation
Collins might have interpreted Kossi’s silence differently if he knew Kossi’s child was sick, his phone had broken, or a family emergency had interrupted the week. The behavior would still be unexpected, but the meaning would change.
That is why context changes everything. A delayed reply after a normal week may feel careless. A delayed reply during a crisis may feel understandable. A blunt comment from someone who is exhausted may land differently than the same comment from someone trying to humiliate you.
Expectations do not live in isolation. They are shaped by timing, relationship history, setting, emotional state, and what we believe the other person knows.
Before turning a violation into a final judgment, it helps to ask, “What context might I be missing?”
Perception changes fast
Unexpected behavior can change how we see people because it interrupts the story we had about them. When Kossi failed to follow through, Collins did not only question the proposal. He questioned Kossi’s reliability.
This is why leaders, friends, parents, coworkers, and partners must understand that reputation becomes part of the message. People do not interpret one action by itself. They place it inside a larger picture of who they believe we are.
If your reputation is patient, one sharp comment may surprise people. If your reputation is defensive, the same comment may confirm what they already believed. If people know you as honest, a mistake may be easier to repair. If they already question your honesty, a small inconsistency may feel like proof.
Expectancy violations theory reminds us that communication is not only about what happened. It is also about what people expected to happen.
Emotional weather makes violations louder
When Collins read Kossi’s short reply, he was already frustrated. That emotional state shaped how he interpreted the message.
“Sorry. Got busy. Looks fine.”
Kossi may have meant, “I apologize. I was overwhelmed, but I reviewed it.” Collins heard, “Your request was not important.”
The emotional climate around a violation matters. When people are tired, anxious, embarrassed, or already hurt, unexpected behavior feels heavier. That is why the emotional weather around a conversation can turn a small violation into a major offense.
This does not mean emotions are wrong. They often signal that something matters. But they can also make us move too quickly from surprise to accusation.
A wiser response might be, “When I did not hear back, I felt like the proposal did not matter. Is that what happened, or was something else going on?”
That question leaves room for truth.
We bring assumptions into the room
Every expectancy violation is filtered through assumptions. We assume what a quick reply means. We assume what silence means. We assume what eye contact, tone, distance, punctuality, or enthusiasm should look like.
But every conversation carries invisible assumptions. There is the person speaking, the person listening, the version each person has of themselves, and the version each person has created of the other.
That is why misunderstandings grow so quickly. Collins was not only reacting to Kossi’s delay. He was reacting to the meaning he had built around the delay.
The goal is not to ignore broken expectations. The goal is to test the meaning before accepting it as fact.
How to use this theory in real life
The first step is to notice when an expectation has been violated. Instead of immediately saying, “They do not care,” try saying, “Something happened that did not match what I expected.”
The second step is to name the expectation. Was it about timing, tone, honesty, respect, closeness, privacy, or follow-through? Many conflicts stay confusing because people argue about behavior without naming the expectation underneath it.
The third step is to ask for clarification before making a final judgment. “I expected to hear back sooner, so I started wondering if something was wrong. Can you help me understand what happened?” That kind of sentence is direct without being destructive.
The fourth step is to repair quickly when you violate someone else’s expectation. Do not hide behind excuses. Try saying, “I told you I would follow up and I did not. I understand why that affected your trust.”
Repair works better when understanding the need beneath the words becomes more important than winning the explanation.
Watch out for this
Expectancy violations theory does not mean every expectation is fair. Some expectations are unrealistic, unspoken, or based on control. No one can meet standards they were never told about, and no healthy relationship can survive if one person treats every surprise as betrayal.
The theory is most useful when it helps people ask better questions. What did I expect? Was that expectation reasonable? Did the other person know it? What meaning am I attaching to the violation? What explanation might I be missing?
One thing to remember
Broken expectations make people search for meaning.
Sometimes that meaning is positive. Someone surprises us with courage, kindness, honesty, or generosity. Sometimes it is negative. Someone disappoints us, embarrasses us, ignores us, or breaks trust.
But the moment between surprise and interpretation is important. That is where wisdom can enter.
Before you turn a violation into a verdict, pause long enough to ask what actually happened, what you expected, and what else might be true.
Reflection question
What recent reaction in your life was less about what someone did and more about the expectation they violated?
