People & Contacts: The I Dimension

Think about the last time you asked a group for ideas. Two or three people started talking before you’d even finished the question. They built on each other, laughed, wandered off on a tangent and came back. One person didn’t say a word the entire meeting.

Then, at nine o’clock that night, the quiet one emailed you the best idea anyone had all week.

Sound familiar? Nobody in that meeting did anything wrong. They just plot at opposite ends of the same scale.

Outgoing, reserved, and everywhere in between

The I in DISC stands for Influence, and it’s about people and contacts: how you connect with others, and how much connecting you actually want in a day. It works as a continuum, not a category.

On one end is the extremely outgoing person. They’re all about people. They’re assertive, fast-paced, and fun, they love a good time, and connecting with others is what fuels them. Put them in a room full of strangers and they’ll know half of them by lunch.

On the other end is the very reserved person. Their preference is to work alone. They communicate in a more reserved way, they want time to process information and think things through, and the last thing they want is to be called on to present off the cuff. They would much rather know what they’re going to say before they say it.

You can fall anywhere in between.

If you’ve already looked at the D dimension and how people handle problems and challenges, this scale works the same way, but it answers a different question. The D asks how you respond to a problem. The I asks how you respond to people.

You can usually see it before anyone says a word

This is one of the easiest dimensions to spot, because so much of it shows up in the body.

I’m outgoing. It’s very hard for me not to talk with my hands, and I’ve stopped apologizing for it. Outgoing people use facial expressions, gestures, the whole body. You can often tell how they feel about an idea before they’ve said one word about it.

ReservedOutgoing

10050100

A very reserved person shows you much less. Their hands might be resting under the desk. Their face stays fairly neutral. There isn’t a lot of body language to read at all.

Neither of those is a problem. The problem starts when we misread them.

I learned that one the hard way. Years ago, I was so excited to meet a client in person after months of working together by email and phone. When she walked into the room, I stretched out my arms and gave her a big hug. I didn’t even notice her body go rigid. I just squeezed tighter, because I was that excited.

She told one of her team members that I clearly hadn’t read her DISC report!

Later that day, after we’d spent several hours together and she was much more comfortable, she told me how uncomfortable that hug had made her. Before we parted, she gave me a hug of her own, and we both laughed. But I’m much more aware now of how easily I hug, and that not everyone appreciates it.

Reserved doesn’t mean shy

This is the misunderstanding I correct more than any other on this scale, and I’ll be direct about it: reserved is not the same as shy, and it is definitely not the same as not liking people.

Here’s what I hear in sessions. “She never speaks up, so I assume she doesn’t care.” “He keeps to himself. Not much of a team player.” “I can’t read him at all, so I figure he’s against it.” Every one of those takes a preference and turns it into a character judgment.

A preference to work alone is about where someone does their best thinking. That’s it. It says nothing about how much they care about the people around them. Some of the most loyal, invested people I’ve worked with plot way out on the reserved end. They just show it differently. You’ll see it in the follow-up email, in the question they had ready because they’d thought about it ahead of time, in the detail they remembered because they were listening while everyone else was talking.

I recently worked with a team of project managers whose leader was misreading exactly this. Several people on her team were quiet, and they didn’t show much on their faces. She read that as disinterest, or as a sign that they had an issue with something. So she kept peppering them with questions, trying to pry it out of them.

What she needed to do was ask a few questions, pause, and give them time to process and answer. But the silence was deafening for her, so she filled every pause with more questions. Those pauses were exactly the time her team needed to think.

When a team gets this wrong, the damage adds up quietly. The reserved person stops being asked. Their ideas get less airtime because they arrive later, in writing, after the “real” discussion is over. And the outgoing people in the room start to believe they’re the only ones with anything to contribute.

That’s not a character flaw on anybody’s part. It’s a misread. And it’s fixable once you know what you’re looking at.

Trust gets built two different ways

This is one of the less obvious differences between the two ends of the scale, and it explains a lot of friction.

Outgoing people tend to extend trust quickly. They connect first, and trust comes along with the connection.

Reserved people tend to build trust more gradually, and information is a big part of how they build it. They want the facts and the data points behind a decision so they can buy in. That’s not suspicion. It’s their route to connecting with you.

So picture what happens when an outgoing leader tries to win over a reserved colleague with warmth and energy and very little substance. It doesn’t land. And when a reserved person hands an outgoing colleague a spreadsheet with no conversation around it, that doesn’t land either. Same good intentions, wrong approach.

Communicating with someone on the outgoing end

Don’t over-data them. I mean it. Too many facts, too many figures, and their eyes will glaze over. They’ll check out, sometimes while still nodding at you.

That doesn’t mean the facts don’t matter. It means the delivery does. If you need to present on numbers, put them in writing and follow up with all the context they’ll need later. Let the conversation carry the point and let the document carry the detail.

And connect with them individually first. That human connection is what makes the data part go well. A two-minute personal conversation before the business buys you far more attention than the most efficient agenda in the world.

For a fuller picture of the most outgoing style, and what it’s like to work alongside one, the guide on how to communicate with a High I goes further into the person rather than the scale.

Communicating with someone on the reserved end

Don’t call them out. A reserved person does not want to be put on the spot for an answer they haven’t had time to form. They want to be prepared. They want to know what’s coming.

So tell them. Send the question before the meeting. Share the agenda. If you need their input on a decision, give them the information and a little time rather than asking for a reaction in the moment. I know that feels slow if you’re outgoing. The answer you get will almost always be better for it.

Give them the facts. Reserved people tend to be very fact-based and information-based, so the data points are part of how they get comfortable with you and with the decision. Skip the information and you’ve skipped the part where they decide to trust it.

And when they’re quiet, don’t fill the silence for them. Quiet is often thinking.

Leading a team that spans the whole scale

Most teams aren’t all one end or the other. You’ll have a couple of people who light up in a group, a couple who’d rather send you their thoughts in writing, and a few somewhere in the middle. Your job as a leader is to know who’s who, including where you plot yourself.

Virtual meetings make this harder, and they make both ends show up more strongly.

If you’re outgoing, keep your camera on. Not for anyone else. For you. Very outgoing people get distracted easily (squirrel, shiny object, oh my goodness, look at that) and the camera keeps you present. I say this as someone who has absolutely chased that squirrel.

If you’re reserved and leading an outgoing group, you’ll probably need to warm the room up a bit before you get to the substance. A little connection at the start goes a long way with that crowd, even when it doesn’t come naturally to you.

And whichever end you’re on, build meetings that work for both. Some talking time for the people who think out loud. Some prep time and a written follow-up for the people who think first and talk later. That isn’t lowering the bar for anyone. It’s how you get the best thinking out of everybody in the room, including the person who’d otherwise send it at nine o’clock at night.

If you want to go further with adjusting how you show up for different people on purpose, adapting your communication style walks through it style by style.

Start with where you actually plot

Knowing where you fall, and where your team falls, is what lets you engage people the way they need instead of the way you’d want. Most of us guess wrong about at least one person. Usually someone quiet.

The DISC assessment shows you where you are on this continuum, alongside the other three dimensions, so you’re working from something clearer than a hunch.

If you’re curious which end you lean toward, take a complimentary DISC assessment. It takes about 10 to 15 minutes, and you’ll come away knowing a lot more about how you connect with people, and why some people seem to connect with you so much more easily than others.

Frequently Asked Questions

What does the I in DISC measure?

The I in DISC stands for Influence, and it describes how you respond to people and contacts. It works as a continuum. On one end are very outgoing people who are assertive, fast-paced, and energized by connecting with others. On the other end are very reserved people who prefer to work alone, want time to process information, and would rather not be called on without warning. Most people fall somewhere in between. Neither end is better. Outgoing people bring energy and connection, and reserved people bring thought and preparation. Knowing where you fall helps you understand why some interactions leave you energized and others leave you drained. The DISC assessment shows you where you plot on this scale alongside the other three dimensions.

Does being reserved mean someone is shy or doesn’t like people?

No. This is the most common misunderstanding about this part of DISC. Being reserved is a preference about how someone communicates and where they do their best thinking, not a sign that they’re uncomfortable around people or don’t care about them. Reserved people tend to want time to prepare, to process information before they respond, and to work on their own. Many of them are deeply loyal and invested in their teams. They simply show it in quieter ways, like a thoughtful follow-up or a well-prepared question, rather than in a lot of talk in the moment. Reading their quiet as disinterest is a misread, and it can cost a team some of its best ideas.

How do I communicate with someone who’s very outgoing?

Connect first, and go light on the data. Very outgoing people are people-focused, so a short personal conversation before the business will earn you far more attention than jumping straight into the details. Avoid burying them in facts and figures, since their attention tends to drift when a conversation becomes all numbers. If the details matter, put them in writing and follow up with the context afterward, so the conversation carries the point and the document carries the detail.

How do I get a reserved person to open up in meetings?

Don’t put them on the spot. Reserved people want to be prepared and to know what’s coming, so share the agenda or the question ahead of time and give them room to think before they answer. Offer the facts and information behind a decision, because that’s a big part of how they build trust and buy in. After the meeting, give them a way to add their thoughts in writing. And when they’re quiet in the room, resist the urge to fill the silence for them. In my experience, the answer you get when a reserved person has had time to think is usually worth the wait. To find out where you and your team fall on this scale, take a complimentary DISC assessment.
