The Stage With Too Many Actors
Your brain has a finite stage. Every unread message, every open tab, every half-finished thought is waiting in the wings. Modern life keeps adding actors until the performance collapses.

Jordan is trying to help with homework. It is a Tuesday evening. The subject is maths, which they are reasonably good at, and the problem is one they can solve. But the solving keeps stopping. A message arrived twelve minutes ago — work, probably nothing urgent, possibly urgent — and they haven’t opened it. That unopened message is somehow still in the room. So is the earlier notification from a family group chat. So is the half-composed reply to a colleague that needs finishing before tomorrow.
The homework is taking twice as long as it should. The teenager has noticed. They haven’t said anything, but they’ve stopped asking for help as often, started guessing instead. Jordan thinks everything is being managed fine.
It isn’t. The stage is full.
There is an assumption built into the design of almost every digital tool we use: that the human mind can hold multiple things at once without cost. That background processing is free. That attention is divisible without loss. This assumption is not a design oversight. It is a commercial convenience. The notification that interrupted Jordan’s evening did not cost the platform that sent it anything. The cost was paid entirely by Jordan, paid in the currency of the cognitive load it added to a stage that was already crowded.
We have constructed our working lives around a belief that multitasking is a skill. Some people have it, some don’t. If you’re struggling, the diagnosis is personal. You need better focus, better discipline, better time management. The problem is framed as yours to solve, which is exactly the framing that benefits the systems creating it.
Mental exhaustion at the end of a day isn’t the cost of hard work, it’s the cost of a cluttered stage where no single thought could hold the floor.
The science on this is not contested. Working memory — the part of the mind actively holding and manipulating information in the present moment — is finite. The most widely cited research puts its capacity at somewhere between five and nine distinct items. When that capacity is exceeded, performance degrades: errors increase, reasoning slows, creativity diminishes, emotional regulation weakens. This is not a metaphor. It is a measurable neurological process.
What is less widely understood is that the stage fills even when you are not actively performing. An unread message, an unresolved task, a open browser tab, a conversation left unanswered, a decision deferred all consume cognitive resources. All of these are actors waiting in the wings, drawing on the same finite supply of working memory whether you are consciously attending to them or not. The stage does not empty when you look away from something. It remains cluttered.
Multitasking, as research has established for decades, does not exist. What exists is task-switching — rapid, costly, and largely invisible. Every switch between demands extracts a penalty. The penalty is paid in attention that does not return to the original task fully or immediately.
The person designing notification settings knows this. The product teams who decided that a message should arrive as an interruption rather than a summary, in real time rather than in a batch, with a sound rather than in silence. Those decisions were not made without awareness of their effect on the receiving mind. They were made with full awareness, and they were made because interruption serves the platform’s interest in ways that quiet does not.
The cost arrives in ways that are easy to misattribute. The teenager interprets the distraction as disinterest. Jordan interprets the exhaustion as a sign of a demanding day. The colleague who receives the half-composed reply interprets the clipped tone as brusqueness. None of these interpretations are entirely wrong, and none of them identify the actual cause.
This is the damage of cognitive overload: it does not announce itself. There is no moment where the stage declares itself full. The performance simply gets worse, slower, less considered, more reactive, less kind. The people closest to you pay the highest price, because the exchanges with them happen in the margins of a mind that has already spent its careful attention elsewhere.
Multiply Jordan by the working population of any developed country, and the scale of what is being quietly extracted, not stolen exactly, but spent at a rate and in a direction that nobody consciously chose becomes difficult to look at directly.
The three questions I bring to any technology are whether it is Assistive, Augmentive, and Adaptive. A notification system that delivers interruptions during Jordan’s evening homework fails all three with some consistency.
It is not assistive. They did not need that message in the moment it arrived. The task already underway, helping a child think through a problem, being present, being useful, was the thing that needed assistance. The notification interrupted it. Assistive technology helps people do what they are trying to do. This did the opposite.
It is not augmentive. Nothing was added to Jordan’s evening that could not have been received in a batch at a time of their choosing. The message was not urgent. Its value did not depend on immediacy. What the interruption added was noise, cognitive load that displaced something of genuine worth.
It is not adaptive. An adaptive system would recognise that Jordan is engaged in something, the phone knows there is homework happening, knows the hour, knows the pattern, and would ask whether now is the right moment. No notification system currently on the market defaults to asking this question, because asking it would reduce engagement metrics, and reduced engagement metrics are a problem for the platform, not for Jordan.
NOW WHAT?
Ask yourself some real questions, you might be surprised by your answers:
Think about the last time you felt genuinely focused, not busy, but actually thinking clearly, at full capacity. What conditions made that possible? How often do those conditions exist in your normal day?
Has anyone in your life — a partner, a child, a colleague — given you the impression that they don’t feel they have your full attention? What would it take to change that, beyond intending to?
What would you remove from your daily information environment if you could? A platform, a channel, a notification category. And if the answer is clear, what is stopping you from removing it now?
If your attention is genuinely finite, if every interruption costs something that doesn’t fully come back, is the way you are currently spending it a deliberate choice, or something that has simply accumulated?
The finite mind isn’t a flaw. It’s a feature that modern systems were not designed to respect.
If you know someone who has been told they need to be better at managing distraction — a colleague, a teenager, a partner — this piece is worth sending to them. The problem is not theirs.
The previous essay in this series looked at what we’ve lost by replacing shared attention with individual feeds — The Campfire Problem. The next looks at what we’re missing in plain sight when our focus is elsewhere.
A note on Jordan
Jordan is a fictional character. Their story is drawn from a combination of professional observation and personal proximity to real events. The experiences described are real. The person is not.
