Have you noticed it?
Forgetting why you walked into a room.
Struggling to start tasks you know need to get done.
Feeling overwhelmed by simple decisions that used to feel automatic.
It’s not your imagination. Executive function, the brain’s ability to plan, organize, focus, and follow through, is under pressure.
And it’s happening across all ages.
The Data Tells the Story
Research shows executive functions begin declining as early as 30-40 years old, with working memory and inhibitory control taking the biggest hits. But some aspects actually improve with age including attentional focus and executive efficiency. These can increase until the mid-to-late 70s.
So, it’s not a simple story of across-the-board decline.
The bigger issue?
Younger adults are struggling too.
Nearly 70% of recent college graduates feel unprepared for real-world tasks like managing finances and securing health insurance. The complexity of adult life has escalated faster than our ability to develop these skills.
The demands on our executive function have simply outpaced our capacity.
The Modern Life Factor
Then there’s what we’re doing to ourselves daily.
Chronic stress impairs working memory and cognitive flexibility. It doesn’t just make us feel overwhelmed, it reduces our ability to use the cognitive control we have.
Technology compounds the problem. Smartphone use impairs inhibition and working memory, with excessive use linked to reduced brain connectivity in regions that control cognition.
Even more striking: just having your phone nearby can impair performance on attention tasks, even when it’s turned off.
We’re being interrupted every 3 minutes on average, and it takes nearly 30 minutes to fully refocus.
No wonder we feel scattered.
The Perfect Storm
What we’re experiencing is a collision of forces:
- Life has gotten more complex and adulting is harder than it used to be
- Chronic stress is eroding our cognitive control systems
- Digital technology is fragmenting our attention constantly
- The structures that used to provide scaffolding (office routines, clear schedules) have disappeared for many
- Even natural age-related changes in some executive functions are happening earlier
The result?
An entire population feeling like their brain isn’t working the way it should.
This isn’t about individual failure.
It’s about unprecedented demands on a cognitive system that wasn’t designed for this level of complexity and distraction.
My Perspective
The conversation around executive function often focuses on individual solutions.
Suggesting we need better habits, more organizational systems, or improved time management.
Those help. But they miss the bigger picture.
We need to acknowledge that modern life has created an environment that actively works against executive function.
The constant connectivity.
The information overload.
The expectation of instant responses.
The elimination of downtime.
Recovery starts with recognizing this isn’t a personal failing.
It’s a systemic challenge.
And maybe, just maybe, we need to redesign how we work and live.
Supporting our brains rather than constantly fighting against them.
