Finding the Signal in the Noise: A Lecture with Greg McKeown

Finding the Signal in the Noise: A Lecture with Greg McKeown

Last night, I attended a lecture by Greg McKeown at Lipscomb University as part of the Don R. Elliott Distinguished Presidential Lecture Series. He began with several engaging exercises, and as he moved into the presentation, I immediately recognized portions of his opening remarks from the introduction and first chapter of his book, Essentialism: The Disciplined Pursuit of Less.

A few ideas and statements stayed with me after the lecture ended.

One of his early observations was simple but profound:

You don't wake up and say, "I would like my day to be full of unimportant things today."

And yet, how often does that happen?

McKeown began talking about the difference between noise and signal, and offered another statement that I found particularly memorable:

Every yes to something nonessential is a no to something essential.

He briefly brought Henry David Thoreau into the conversation, referencing Walden and Thoreau's desire to "drive life into a corner, and reduce it to its lowest terms." It is a reminder to strip away what is unnecessary so that we can recognize what actually matters.

The Constraint We Don't See

McKeown then posed a question:

What's the primary bottleneck in a world outside yourself?

His answer was a reminder that if you focus on everything except the constraints, you may actually make things significantly worse.

He illustrated this with a story about a group of hikers. The group's progress was limited by its slowest member. Rather than simply pushing everyone harder, the solution was to put the slowest hiker at the front and eventually redistribute the weight in that person's backpack.

The point? Identify the actual constraint.

But sometimes the constraint is invisible.

This led to a discussion of communication, including a story about Microsoft's leadership culture and Satya Nadella introducing Marshall Rosenberg's Nonviolent Communication to his senior leadership team.

And this is where McKeown spent a considerable amount of time on an equation that became the centerpiece of the lecture:

Clarity = Signal / Noise

He emphasized that noise is in the denominator.

As noise increases, clarity decreases. Eventually, we reach a threshold where the noise becomes too great for the signal to get through.

Without intentional and disciplined effort, communication becomes increasingly difficult. We have to learn not only how to speak with clarity but how to communicate in ways that allow others to hear and understand us.

McKeown introduced a term I particularly liked: signalist.

A signalist is someone who understands the equation. Someone who can recognize the signal in the noise, communicate with clarity, and help others do the same.

His observation was that there is high demand and low supply of signalists.

I suspect he is right.

Understanding and Being Understood

One of the most interesting parts of the lecture was his discussion of listening.

McKeown referenced the work of Carl Rogers and Richard Farson, who helped introduce and popularize the concept of active listening.

He challenged the idea that listening is simply about being empathetic or waiting for your turn to speak. It is a balance between understanding and being understood.

He offered a simple progression:

• Listen.

• Reflect.

• Speak.

• Confirm.

He also made a point that I think deserves more attention:

Being understood is just as important as understanding.

One suggestion was to resist making your point until the other person has satisfactorily made theirs. In other words, don't rush to respond. Make sure you have actually heard what the other person is saying.

There is a difference between hearing words and understanding meaning.

Communication in the Age of AI

When asked about companies downsizing, McKeown shifted the conversation toward artificial intelligence.

He described the AI age as an age of disorientation.

Importantly, he made it clear that he was not anti-AI. Rather, he emphasized the increasing importance of our ability to talk with real people about real things.

As technology continues to change how we work, communicate, and process information, the human ability to listen, understand, and be understood becomes even more important.

He offered an example of a high-performing signalist by referencing the film Arrival. Specifically, Dr. Louise Banks, the linguistics professor portrayed by Amy Adams.

It was an interesting choice, particularly given another idea he shared:

Life is limited by language.

The words we have available, the meanings we assign to them, and our ability to communicate those meanings shape how we experience the world and one another.

McKeown also brought Rumi into the conversation:

Out beyond ideas of wrongdoing and rightdoing, there is a field. I'll meet you there.

I found that particularly fitting within the larger discussion of communication. What might happen if we spent less time preparing to defend our position and more time trying to understand someone else's?

A More Personal Moment

Toward the end of the lecture, McKeown shared a deeply personal story involving the death of a close friend and, separately, the death of his mother. He reflected on the very different communication histories he had with the two of them. With his friend, communication had been frequent and open. His relationship with his mother had been quite different.
It was an emotional moment, and one that brought the larger discussion of communication into a very personal context. We don't always recognize the importance of the conversations we have, or the ones we don't have, until we no longer have the opportunity.

It also brought to my mind the Hawaiian practice of Ho'oponopono and its familiar prayer:

I'm sorry.
Please forgive me.
Thank you.
I love you.

It was a reminder that communication isn't always about having the right words or making the perfect argument. Sometimes it is about acknowledging, listening, forgiving, and making a connection.

Assume You Don't Understand

As the lecture wrapped up, McKeown was asked for practical tips.

His answer was wonderfully simple:

Assume you don't understand.

I keep coming back to that.

Assume there is something you haven't heard. Assume there is context you don't know. Assume the other person's perspective may be different from your own. And before you respond, make the effort to understand.

Perhaps that is where being a signalist begins.

In a world increasingly filled with noise, information, opinions, and competing demands for our attention, clarity is not accidental. It requires intention, discipline, and a willingness to listen.

And sometimes the most essential thing we can do is stop talking long enough to hear the signal.
