When Signals Become Noise

Signals are supposed to help you see what’s happening.

To reduce uncertainty.
To guide decisions.
To show what’s working.
To elicit action or reaction.

That’s the idea.

A fire alarm is a signal. You don’t question it. You act.

➡️ Until it goes off too often. Then you stop reacting.

A car horn is a signal. It jolts you to attention. You survey. You decide.

➡️ Until it’s constant (traffic). Then it becomes background. (And you turn up the radio.)

The notification chimes of your smartphone are signals. At some point, frequency turns signal into something else.

Signals offer safety.

Signals offer direction.

Signals provide clarity.

Metrics Don’t Just Measure. They Signal.

Many metrics operate the same way. They don’t just measure.
They signal.

• What to notice.
• When to act.
• What matters.

NPS scores signal customer sentiment. Until they’re optimized… and stop reflecting it.

Annual performance ratings signal contribution. Until they become theater… and stop guiding it.

Once the system starts optimizing the metric… the signal stops being reliable.

Not all at once.

At first, it’s subtle.

• The numbers still move.
• The dashboards still update.
• The reports still look consistent.

Nothing appears broken.

That’s what makes it dangerous.

Because now the system is no longer showing reality. It’s showing a version of reality that satisfies the system.

The signal hasn’t disappeared.

It’s been reshaped.

What used to indicate progress… now indicates alignment with the metric.

☝️ Those are not the same thing.

You start seeing improvement where there isn’t any. Stability where there’s drift. Success where there’s substitution.

And because everything still looks coherent… you trust it.

That’s the trap.

The system isn’t just producing outcomes anymore. It’s producing belief.

Belief in the number.

If the signal says things are working… you assume they are.

Even when something feels off.
Even when the experience doesn’t match.
Even when the results don’t hold up outside the system.

Because the system is consistent. And consistency feels like truth.

But consistency is easy to manufacture… when the system controls what gets measured.

Over time, this creates a new problem.

Not bad decisions. Confidently wrong decisions.

• Decisions made with clean data.
• Clear dashboards.
• Strong signals.

And none of it pointing to what actually matters.

This is where trust in the people starts to break. Not because the system fails. Because the metric has become more believable.

And once something is believable… it’s much harder to question.

Even when you should.

The distortion to hang with

A signal is only useful if it reflects reality.

Once it starts reflecting the system instead… clarity becomes confidence without truth.

And that’s when the system stops helping you see… and starts helping you believe.
