Two blue ticks. No reply. A meeting invite disappears from your calendar. Someone’s tone changes slightly on a call. A colleague glances at another person after you speak. A friend goes quiet after a message that mattered to you.
And almost instantly, your mind begins to write a story. The human brain is designed to close gaps. For most of human history, uncertainty was dangerous.
If our ancestors didn’t know where the threat was coming from, they didn’t get to casually “wait and see.” Ambiguity could mean exclusion from the tribe, loss of protection, or physical danger.
So the brain evolved to do something extraordinary: It became a meaning-making machine.
When information is missing, the nervous system fills in the blanks.
Usually through three unconscious questions:
- What’s happening?
- What does it mean?
- What should I do?
That sequence is essentially a story structure.
Situation.
Interpretation.
Response.
Your nervous system prioritises certainty over accuracy. Which means the story that appears first is not necessarily the truest story. It’s the story most likely to restore a sense of safety.
That’s why silence can feel so emotionally loud. A delayed response becomes: “They’re annoyed with me.” Or a serious facial expression becomes: “I’ve done something wrong.” Someone else succeeding becomes: “I’m falling behind.”
The brain would often rather invent certainty than tolerate ambiguity. What fascinates me is how modern life constantly activates this ancient wiring. We no longer spend our days scanning forests for predators.
Instead, we scan: unread messages, email tone, Slack punctuation, meeting dynamics, social media comparisons, group chat silence, delayed responses and digital visibility metrics.
Ancient humans feared what was hiding in the dark. Modern humans often fear what’s hiding in other people’s minds.
And because digital communication contains so many informational gaps, our nervous systems are now filling in blanks all day long.
Most people assume overthinking is a flaw in personality. I think it’s more accurate to view it as unfinished pattern recognition. The mind is just trying to complete the picture.
The challenge is that survival wiring doesn’t produce objective reporting but instead protective interpretation. Which is huge. Because many of the stories people live inside are not facts. They are nervous-system-generated predictions designed to avoid pain.
Repeated often enough, these narratives stop feeling like thoughts and like identity. And this is where things become costly. People begin shrinking in rooms they were meant to contribute to.
They over-explain to avoid rejection. They become hyper-attuned to approval or abandon ideas halfway through expressing them. They optimise for belonging over honesty.
What’s powerful is that awareness creates separation.
The moment you can say:
“The story I’m telling myself is…”
…you interrupt the automatic nature of the script. That single sentence creates psychological distance between: the event, the interpretation and the identity attached to it.
One of the simplest exercises I’ve started using is to ask:
“What story am I treating as fact that is actually just my nervous system trying to feel safe?”
A gap is not a verdict, and the stories we tell ourselves are not always true. Sometimes they are ancient protection mechanisms wearing modern clothes.
The goal isn’t to stop the brain from writing stories. Humans are storytelling creatures by nature. The goal is to notice the script before it quietly becomes identity.

It’s about how humans turn uncertainty into meaning, and why the nervous system writes scripts we didn’t consciously choose.
And because this is something I think affects almost all of us in modern life, I also created a companion guide to help people catch the script before it becomes identity.
If you’d like the free guide just send me an email hello@helenpackham.com with STORY and I’ll send it to you, no opt in needed.
We tell ourselves stories ALL day every day, but we can also choose how they affect our lives, for the better.
PS: Doors to The Story Room are still open for a limited time. Some of the most important things you have to say are the hardest to put into words. Because they carry so much weight.
If you’re sitting on something that isn’t quite working yet,
I hold a space in The Story Room. We take the messy version and shape it into something you can actually use. Bring one story, idea or message and leave with the words.
