Signals

As you sit and read this, your body is in motion.

Signals are being sent between cells, across systems, from one part of you to another. You’re not aware of them. You don’t need to be. Over the next few minutes, tens of thousands of these signals will pass quietly through your body. By the end of the day, there will have been billions.

Most will arrive exactly where they are needed. Some will not. A receptor may fail. A signal may be weakened, delayed, or misread. When that happens, other signals follow. Adjustments are made. Compensations begin.

Long before anything is felt, the body has already noticed and responds. This is how complex systems maintain themselves—not through constant intervention, but through continuous signaling, adjustment, evaluation and response.

The body is not the only system that works this way. Organizations function in much the same manner. A constant stream of messages, signals, and information is generated and disseminated at every level of the chain. From the reception desk on the ground floor, to the corner office at the top of the building, and of course the boardroom.

These might be small changes in behavior, a change in reporting lines, fluctuations in performance, market developments, changes in the way information moves through the system. Most are absorbed without consequence. But some are not.

A delay here. A hesitation there. A pattern that shifts slightly, almost imperceptibly. Nothing that demands immediate attention. Nothing that forces a response. And yet, these are often the first indications that something deeper has begun to change.

The human body is a signaling system of extraordinary complexity. At any given moment, countless messages are being exchanged—chemical, electrical, hormonal—coordinating functions across the whole. Over the course of a day, these interactions number in the billions. Most pass without notice. All are essential.

Notably, most systems failure does not begin with collapse. It begins with distortion. Signals that once moved cleanly begin to arrive late. Information that was once clear becomes ambiguous. Feedback loops tighten or fall silent. The system continues to function, often for a long time, but it is no longer operating with the same precision.

To an outside observer, nothing appears wrong. Output may even remain strong. Performance, on the surface, is maintained. But internally, the quality of communication has already shifted. And it is here, in these early distortions, that the future of the system is decided.

Healthy systems are not those that avoid disruption. They are those that detect it early, while the signal is still faint, while adjustment is still possible.

The body does this continuously. A slight change in glucose is met with a hormonal response. A minor strain in tissue triggers repair. An imbalance is sensed, and a cascade of signals is released—not to suppress the disturbance, but to restore coherence.

This is not a process of force. It is a process of communication. When the signals are clear, the system adapts. When they are not, the system compensates. And compensation, over time, becomes strain.

This is not abstract. It is familiar. A muscle tightens after exertion. Something has been stressed, repair is required. Left alone, the body responds, blood flow increases, tissue rebuilds, strength returns.

But the signal can be overridden. Pain might be reduced with some form of medication. The symptom is reduced, activity continues, but the underlying strain remains. The message was sent, but it was not acted upon.

Or something more subtle. A growing fatigue at the end of the day. Legs that feel heavier than they did a year ago. Recovery that takes slightly longer. Nothing dramatic. Nothing that demands attention. And so it is ignored.

But these, too, are signals. Not of failure, but of change. The system is adjusting. Or trying to. And whether that adjustment succeeds depends on whether the signal is recognized, or dismissed.

As we age, these signals begin to change—not only in how they are felt, but in how they are generated and processed within the body. Hormonal messages that once drove repair and adaptation become less pronounced. Cellular pulses that initiate recovery are slower, or less responsive. Inflammatory signals remain active for longer than they should. The body’s ability to generate energy, at a cellular level, becomes less efficient.

This is not simply decay. It is a change in responsiveness. A system that once reacted quickly and clearly now requires stronger, more consistent signals to produce the same effect. And that, in turn, requires something more of us.

Not intervention in the sense of control, but participation. A conscious recognition that the system will not maintain itself in the same way it once did, and that adaptation—deliberate, sustained—becomes part of the process. None of this is abrupt. None of it is dramatic. But it is cumulative.

The same pattern can be seen in organizations, but here the failure is often easier to overlook. Signals do not always travel freely. They are filtered, delayed, or stopped altogether.

Information may sit within a team, never reaching decision-makers. A concern may be softened as it moves upward, losing urgency at each level. A weak signal, visible on the ground, may never be recognized as significant until it has already become a problem.

In many cases, the system does not lack information. It lacks transmission. Or worse, it lacks permission. People see the signal. They hesitate to pass it on. Or they adjust it—subtly, unconsciously—so that it fits expectation instead of reality.

The same dynamics are present in relationships. Here, too, systems are sustained through signaling. A glance held a fraction too long. A hesitation before answering. A touch ignored. A shift in tone so slight it can be dismissed, even by the person who notices it.

In public life, where the same pattern appears, the consequences are more stark. At Enron, apparent profits were sustained through off-balance-sheet structures that concealed debt and inflated earnings. Internal concerns and external questions were present long before the company unraveled. The warning signs were embedded in the numbers themselves. Profits were reported without corresponding cash, debt was moved off the balance sheet through opaque structures, and even basic questions about how the business generated earnings were met with unclear answers. They did not alter the trajectory.

In the case of Bernie Madoff, who for years reported steady returns while no real underlying trades existed, positive returns appeared even when markets were falling, a pattern of relentless and consistent gains. The signals were not subtle. Implausible returns with an unverifiable strategy. Warnings were raised to regulators well before the collapse. Detailed. Specific. Repeated. Ignored.

In the abuse scandals within the Catholic Church, where allegations were reported,

documented, and often contained or reassigned over extended periods, the pattern extended across countries and decades. They weren’t unknown. They were simply deflected.

In each case, when the full scale became visible, the response was immediate and familiar: shock, disbelief, and the question: how could this have happened without anyone knowing?

But really, the more precise question is: how could it have happened when so many people, in different ways, already knew? The signals were not missed at all. They were seen, and then set aside. Not because they were invisible, but because following them would have required something else; attention, disruption, risk.

It is often easier to treat a signal as incidental than to accept what it might imply.

Easier to defer. Easier to wait. And so the signal is not denied. It is absorbed.

Normalized. Until it no longer feels like a signal at all.

For years, leaving aside legal constraints, women described experiences that were widely minimized or reframed. Comments dismissed as harmless. Behavior excused as normal. Patterns of discomfort explained away as misunderstanding or oversensitivity.

Individually, each instance perhaps was small enough to ignore. Or at least to reinterpret. But they accumulated. And when those accumulated signals eventually surfaced more visibly, in movements such as MeToo, they appeared, to many, as a sudden rupture.

They were not sudden. They were the consequence of signals, of evolving social understanding and the transforming zeitgeist that had been present, repeated, and largely unacknowledged for decades.

In the years leading up to the 2016 election of Donald Trump, the signals weren’t hidden, in fact they were repeated. A presidential candidate publicly mocking a disabled reporter and the moment passing without lasting consequence. A proposed ban on entire groups entering the country, first treated as rhetoric, then as policy. The phrase “fake news” entering common usage, not as critique, but as dismissal. Crowds chanting to imprison a political opponent and the language becoming normalized through repetition.

Each moment, taken alone, could be dismissed. An outlier. A tactic. A reaction.

But they accumulated. What changed was not a single event, but the threshold of what could be said without consequence. And as that threshold shifted, so did the range of what could be accepted.

The outcome did not arrive without warning. It arrived after a sequence of signals that were visible, repeated, and largely discounted in real time. The difficulty is not that signals are hidden. It is that they rarely arrive in a form that compels us to act. They arrive early, when there is still time to respond. And because of that, they are easy to dismiss.

A central theme of recent political messaging was a move away from further military entanglement. Yet the current conflict with Iran sits in stark tension with that position. Public response has been consistently negative, with polling reflecting broad opposition and uncertainty about direction. At the same time, economic pressure has intensified, shaping perception as much as policy. Yet none of these signals, on their own, appear decisive. Each can be explained within the moment. But taken together, they point to something more direct — a widening gap between what was promised and what is now visible.

The signal is present. It is recognized. But it is not permitted to take form.

As Daniel Kahneman perfectly observed, “what you see is all there is.”

What is immediately available, coherent, and consistent is accepted. What is not is set aside.

But the mechanism runs deeper. To follow a signal to its conclusion is rarely neutral.

It carries implication. A pattern, once acknowledged, may require a response. A concern, once voiced, may disrupt stability. A conclusion, once reached, may alter how things must be seen.

And so, the signal is not rejected. It is contained. Allowed to exist, but not to connect. Recognized, but not pursued. We act, not on the totality of what is available, but on what we are prepared to accept. The difficulty is more than detection. It is acknowledgement.

Across the body, in organizations and in relationships the pattern holds. The system is undeniably communicating. The question is not whether the signal is present, but whether we are prepared to follow it.
