Anxiety is an invisible tax on almost everything we do. We have a limited amount of working memory and cognitive function in any given moment. Anxiety taxes that and diminishes our capacity. We Begin…
We want to try something for a moment.
Think of the last time you were really worried about something.
Not a passing concern, but actually genuinely worried.
Something that kept returning throughout the day.
Okay, got it? Good.
Now, think about what else you were trying to do that day.
Work, study, have a conversation, make a good decision, think creatively.
So how did that go? So if we're honest, probably it didn't go as well as it should have.
We were there physically, but part of us was somewhere else entirely, running the worry loop, trying to solve the unsolvable, preparing for the worst.
We were paying without knowing it, what we like to call the invisible tax.
So here's what's actually happening.
This is where cognitive science gets us something genuinely important.
Our brain has a system called working memory.
Think of it as your mental desktop.
We're talking about that active workspace where thinking, reasoning, and learning actually occur.
It's where you hold information while you process it, make connections, solve problems, and construct new understandings.
It is, in the most direct sense, where learning happens.
Here's the critical thing.
Working memory has a strictly limited capacity.
It can hold and process only a small number of things at once.
Researchers generally put this at around four to seven chunks of information for most people, though the quality of those chunks matters enormously.
When your working memory is full, new information either displaces what's already there or fails to make it at all.
So now, inner anxiety.
When you're anxious, even mildly, even at a level that you might not consciously have identified as anxiety, your working memory is being harshly occupied by threat-related thoughts, the what-ifs, the mental rehearsal of negative outcomes, the background hum of worry about whether you're good enough, fast enough, smart enough, prepared enough, All of that is not idle background noise.
It is actively consuming cognitive resources that would otherwise be available for learning.
