Finding the true signal: Learn to read the water, and ride the waves.

A few years back, I was shopping for a property and narrowed it down to two neighboring cities. Both of the locations fit my criteria, were within my budget, and after careful consideration, I picked the one that was most recommended and selling fast.

Over the years, the other location quietly grew with new malls, communities, parks, and headquarters. Their prices started to climb while mine stayed flat. My purchase decision was based on solid data, including how fast homes were selling, the city’s projected growth rates, and pricing trends.

What I didn’t look at was the city council’s long-term vision, the mayor’s public commitments, and the vast stretches of vacant land with fewer zoning restrictions. This combination of factors led to the growth of the other location, and the future was being quietly assembled there. In my decision, the louder location won my attention but the quieter one built the future.

I eventually sold, moved over, and paid a higher premium in the other city for what I could have bought at a discount. Most of us are trained to trust the visible, the measurable, and the hot, fast-moving information, which I later understood as noise.

Signal vs Noise:

A signal is information that helps you change your understanding, make better decisions, or improve outcomes. Noise is everything else, it distracts, misleads, and makes you emotional. A signal is quiet, irreversible, infrequent, and often boring. Noise is quite the opposite, it is louder, common, and ultimately useless. Once you learn how to differentiate signal from noise, the application becomes easier and more natural across all aspects of life.

In cybersecurity, an employee account that usually doesn’t have access suddenly connects to a sensitive database it has never accessed before. This is a very strong, high-fidelity signal. Responding to every single scan by bots that constantly scan your public firewall ports is a waste of resources. Noise expends your valuable resources and lets the signal go unnoticed.

At the workplace, the best employees choosing to stay and the improving quality of work is a strong signal of a healthy culture. On the other hand, if high-performing employees quietly leave every six months, this is a strong signal that you need to make changes. Most workplace gossip and people looking busy just for show are noise that can be discarded. Leaning into signals helps leaders organize better and deliver results.

Missing signals in geopolitics is costly and dangerous. A country builds a high-quality transportation network connecting landlocked resources and isolated towns, which could be used for both civilian and military purposes. A good leader will hide this signal within the noise of handshakes and non-binding cooperation agreements signed at highly public events that lack specific budgets or timelines.

The setting changes, the plot doesn’t. Signal is quiet, consequential, and always competing with noise for your attention. The most dangerous players know exactly how to tip that competition in their favor.

How to Find the Fixed Star Among Moving Ones?

Finding a signal is less about technique and more about what you’re willing to stop doing. It starts with subtraction and letting go of what you already know. Approach each decision and data point with a fresh set of eyes, without any preconceived notions or formulas. Most people look for supporting data for the decision that was already made. Data is always available, don’t rush to understand it before observing it. As you develop this skill, you will miss signals, and the goal is to miss fewer over time.

A signal is rarely an isolated thing, and a single data point is rarely a signal. Instead, look at the entire system that creates them, and pay attention to the currents carried by unrelated sources. City council announcements, the mayor signing deals with Fortune 500 companies, vacant lands taking shape,  these are the quiet data points created by an efficient system assembling the future. But those go unnoticed against your friends’ recommendations, sales growth, and price movements. No single data told me anything but all together gave a strong signal to buy which I missed. Systems thinking helps you identify a fidelity signal.

Finally, a signal rarely proves anything definitively. It only increases or decreases the likelihood of something being true or happening. Asking “Is this true or false?” is not useful; instead, ask “If I ignore this entirely, would my decision change in six months?” If not, it’s noise, let it go.

Finding the signal is not the hardest part. The hard part is acting on a quiet truth that demands a radical, often unpopular change. The true test of leadership is not in finding the signal, but in having the conviction to move your entire ship based on the whisper of the tide.
