Certainty Volatility Theory (CVT): Maybe We Don't Fear Uncertainty. Maybe We Fear Unstable Certainty.
Certainty Volatality Theory: Maybe We Don't Fear Uncertainty. Maybe We Fear Unstable Certainty.
Certainty Volatility Theory
Maybe We Don't Fear Uncertainty. Maybe We Fear Unstable Certainty.
[ Author's Note : This article presents the conceptual framework of Certainty Volatility Theory, proposed by Piyush Gupta. The manuscript was developed with the assistance of a large language model (LLM) as a writing and editing tool. All original ideas, concepts, and theoretical propositions are attributed to the author. ]
For years, psychology has told us that humans dislike uncertainty.
We don't know if we'll get the job.
We don't know if our relationship will last.
We don't know what the economy will look like next year.
The common explanation is simple: uncertainty is uncomfortable.
But there's something this idea doesn't explain.
Some people live happily with enormous uncertainty. Freelancers,<br>entrepreneurs, explorers, researchers—they often have no idea what tomorrow<br>looks like, yet many thrive.
At the same time, someone with a stable office job can become overwhelmed after<br>a week of mixed signals from their manager, despite objectively facing much<br>less uncertainty.
Why?
Maybe uncertainty isn't the thing we're reacting to.
Maybe it's something else.
A Different Variable
Imagine two people.
Person A believes there's about a 60% chance they'll get promoted.
That estimate barely changes for six months.
They don't know the outcome, but they feel relatively calm.
Person B
Monday: "I'm definitely getting promoted." (95%)
Tuesday: "Actually, I think I'm in trouble." (20%)
Wednesday: "No, my boss smiled at me." (85%)
Thursday: "Maybe they're replacing me." (30%)
Friday: "Everything's fine." (90%)
On average, both people are equally uncertain.
But psychologically, they're living in completely different worlds.
The second person isn't just uncertain.
They're rebuilding their understanding of reality every few hours.
Certainty Volatility Theory (CVT)
The human mind may care less about how certain it is, and more about how stable<br>that certainty remains over time.
In other words, our brains may not optimize for certainty itself.
They may optimize for predictable confidence.
A stable 60% belief could be easier to live with than confidence that swings<br>wildly between 20% and 95%.
Why Constant Fluctuation Is Expensive
Every decision depends on our current model of the world.
Should I apply?
Should I invest?
Should I trust this person?
Should I prepare for bad news?
When confidence changes dramatically, those decisions have to be recalculated.
Plans are abandoned.
New plans are created.
Then abandoned again.
The cost isn't simply emotional.
It's computational.
The brain keeps rewriting its own operating manual.
Doomscrolling Is a Perfect Example
Imagine reading the news for an hour.
One article says the economy is booming.
Another predicts a recession.
A third says AI will create millions of jobs.
The next says it will eliminate them.
None of these articles completely convince you.
But each nudges your confidence in a different direction.
By the end, you may know no more than when you started.
Yet you're mentally exhausted.
Perhaps the exhaustion comes not from uncertainty itself, but from repeatedly<br>revising your internal model of reality.
Relationships Feel Hard for the Same Reason
Think about two relationships.
The first is uncertain.
Your partner is long-distance.
You don't know exactly where things are headed.
But they're consistent.
Their words match their actions.
Their affection remains steady.
Now consider another relationship.
Some days you're their priority.
Other days they disappear.
One week they talk about the future.
The next week they seem emotionally distant.
Both relationships contain uncertainty.
Only one forces your confidence to oscillate constantly.
That's often the one people describe as emotionally draining.
The Difference Between Uncertainty and Volatility
These ideas sound similar, but they're not.
Uncertainty asks:
How sure am I?
Volatility of certainty asks:
How often does my level of confidence change?
Someone can be permanently uncertain but psychologically stable.
Someone else can be highly confident most of the time but emotionally<br>exhausted because that confidence repeatedly collapses and rebuilds.
A Different Way to Measure Mental Load
Psychology often asks questions like:
How confident are you?
How optimistic are you?
How anxious are you?
CVT suggests another question:
How many times has your confidence changed dramatically this week?
A higher frequency translates to a higher level of effort and stress caused.
