Your brain is not broken. It's just running old code

Ever wonder why your brain scans for threats before coffee? It's not a flaw, it's evolution. Discover how naming your negativity bias can help you reclaim your focus and calm.

Text 'Your brain is not broken... It's just running old code' over a blurred audience watching a presentation.

You wake up, and before you've made coffee, your brain has already scanned for threats, replayed yesterday's awkward conversation, and reminded you of three things you haven't done yet.

This is not a character flaw. It's a feature — one that kept your ancestors alive on the savannah but is somewhat less useful in a Tuesday morning meeting.

The brain has a negativity bias. It is wired, by evolution, to prioritise threat over opportunity, problem over progress, loss over gain. And it does this automatically, efficiently, and without asking your permission. Here's what the neuroscience tells us: awareness of the bias is the first step to loosening its grip. You can't think your way out of a pattern you can't see. But once you can see it — once you notice the loop running — you have a choice about whether to follow it.

That pause between stimulus and response is not a small thing. It is, neurologically speaking, where change begins. One thing to try today: the next time you catch your brain catastrophising, name it out loud — even just in your head. "There's the negativity bias." Naming it activates the prefrontal cortex and creates just enough distance to choose a different response.
