Three Seconds to Credibility: How Teenagers Instantly Read You

When you work with teenagers—or simply try to have a normal conversation with them—you quickly realize that communication is both the most beautiful and the most complex thing in the world. They are honest to the point of discomfort, fast like notifications, and brutally precise when it comes to detecting anything inauthentic. If you lie to them, list buzzwords, or try to “sell wisdom,” they feel it instantly. If you are real, they respond in kind.

Learn From Them

I felt this very clearly last week while working with a group of teenagers—young artists in a high school in Zagreb. I arrived with the idea of explaining something to them about communication, presentation, and performance. Very quickly, I realized that I was the one who needed to listen.

In their questions, comments, and reactions, you can clearly see how they view the world: more directly, less burdened by form, and far more focused on substance and meaning. What matters to them is not how something sounds, but whether it is true. Whether it is fair. Whether it is theirs.

Teenagers will dismantle you in seconds if you play authority instead of being human.

That is why this text applies equally to them and to everyone who works with them, teaches them, lives with them, argues with them, and tries to explain fractions, life, communication, and relationships.

A Few Seconds to Pass or Fail

Young people live in an information whirlwind: a 12-second video, a meme, a notification, an ad, another video, a friend’s message, a parent texting “where are you???”, while a teacher tries to explain photosynthesis. Expecting full attention in that environment is like expecting zen silence on a TikTok For You page.

And yet—it is possible. But only if communication is clear, concise, direct, and human. In other words: real.

One of the biggest mistakes adults make is assuming that teenagers do not listen. They do listen—very carefully. They just filter aggressively. I saw this again in the workshop with young artists. When I started explaining how a presentation should look, interest dropped. When I asked how they wanted to tell their story and what they wanted the audience to feel, the room came alive.

Don’t Be a Boomer

If you sound like you walked straight out of a 1987 handbook, you have no chance. If you start with an example, a question, or a personal experience—you earn their attention.

A classroom example:One geography teacher starts the lesson with:“Today we will learn about climate change.”Half the class mentally checks out.

Another teacher, same topic, says:“Calculate how many minutes you would survive in the desert without water. Go.”Attention secured.

The topic did not change. The approach did.

Communication with young people must be clear—but young people also need to learn to be clear. Communication is a two-way street, not a one-way lecture. If you use five sentences where two would do, you lose them. The same goes the other way around: when a teenager speaks in half-sentences and expects you to understand everything “from context,” problems arise.

A simple rule saves family lunches, school projects, presentations, and relationships alike: say what you want, why it matters, and what you propose.

The Nonverbal Radar

Teenagers have an exceptionally sharp nonverbal radar. If you stand in front of them looking like you want to escape your own body—they notice. If you are open, calm, and honest—they notice that too. In their world, body language is Google Translate for emotions.

At one workshop, I watched a boy present his work. Hands in pockets, shoulders down, eyes on the floor. No one listened. Not because the work was bad, but because his nonverbal message said: “I don’t believe in myself.”

We repeated the presentation with minimal changes—open posture, eye contact, hands out of pockets—and everything changed. Same person. Same work. Different energy.

Tone of voice matters just as much. Teenagers hate mumbling. But they also hate adults who speak monotonously, without rhythm or emotion. People, regardless of age, listen when they feel that the speaker genuinely cares.

Listen. Really Listen.

Listening is perhaps the most underrated part of communication with young people. Everyone asks, “Why don’t they listen?” Rarely do we ask, “Why don’t we listen to them?”

In workshops, I have seen how much it means when someone reflects their thought instead of skipping over it. When a teenager says, “I feel like no one takes me seriously,” and you respond with, “So you feel like people don’t listen to you the way you would like them to”—trust is built.

When it comes to presentations, remember this: young people do not like encyclopedias. They like stories. Once they understand that every presentation has a character, a problem, and a solution, they flourish.

One student started her presentation on screen addiction with: “Last night I scrolled until 2:47 in the morning. I don’t even know how. Sounds familiar? ”The class was hers.

Stage fright is normal. I see it in teenagers and in adults. The difference is that young people do not hide it. And that is their strength. Fear means you care.

Don’t Be Perfect—Be Real

What those young artists taught me last week is simple and powerful: they are not trying to be perfect. They are trying to be real. And that lesson applies to all of us.

Communication is not theory—it is relationship.Not a monologue, but an exchange.Not perfection, but courage.

The best communication happens when both sides stop performing and start listening.
