The exhaustion of vigilance

You’re reading part of The Collapse of Knowledge, a long-form series about what happens when certainty stops working.

Each chapter stands alone, but together they trace how trust in expertise fractures, why confident nonsense thrives, and what remains when you stop needing to be right. You can read this piece in isolation, or explore the full sequence from the beginning.

There is a particular kind of tiredness that comes from never quite trusting the ground beneath your feet.

It is not the fatigue of effort or overwork. It is the weariness of constant monitoring. Of scanning every claim, every recommendation, every confident voice for hidden assumptions and misaligned incentives.

Once trust becomes conditional, vigilance becomes permanent.

At first, this feels like intelligence doing its job. You are being careful. Responsible. You are no longer outsourcing your thinking to authority.

But vigilance has a cost.

Every decision takes longer. Every piece of information demands evaluation. Even simple choices begin to carry disproportionate cognitive weight.

Should I believe this?

Should I act on that?

What am I missing?

Who benefits if I accept this explanation?

The nervous system does not experience this as thoughtful engagement. It experiences it as threat detection.

Your body stays partially braced. Alert for error. Primed to correct. There is no true rest state, because certainty no longer provides one.

I noticed this most clearly in moments that should have been neutral.

Reading the news. Listening to conversations. Watching people argue online. My mind automatically generated counterpoints, caveats, alternative explanations.

Not because I wanted to argue.

Because I could no longer switch the process off.

This is where scepticism quietly turns from skill into burden.

Western culture frames vigilance as virtue. Stay informed. Stay critical. Stay alert. But sustained vigilance without recovery erodes resilience. You cannot live indefinitely in analytical mode without paying a physiological price.

Vietnam disrupted this pattern not by offering better information, but by modelling proportion.

People here are attentive without being hypervigilant. They notice what matters and let the rest pass. Not out of apathy, but out of calibration.

When systems are known to be flexible, vigilance can relax. You adapt in real time rather than pre-emptively guarding against every possible failure.

I learned to stop scanning for certainty and start scanning for cues.

Who is involved?

What is changing?

What can be adjusted if this does not work?

Vigilance narrowed. Energy returned.

The exhaustion I had attributed to complexity was actually the cost of permanent epistemological defence.

Once I let go of the idea that everything needed to be evaluated before it could be lived, my nervous system finally stood down.

Not because the world became safer.

But because I stopped treating it as something that had to be constantly audited.
