The cost of being interrupted

Sending a message takes a few seconds. Understanding it can take considerably longer.

The sender knows the background. The recipient may have to reconstruct it, decide whether a response is necessary, find the missing information and return to whatever they were doing before.

The cost of sending and the cost of receiving are different. A great deal of digital life is organised as though they were the same.

As communication becomes easier to produce, that difference deserves more attention.

A small cost multiplied

Consider an ordinary working morning. A person receives a vague request, a meeting invitation without an agenda and several updates whose relevance is unclear.

Each item appears minor. Together, they require a succession of decisions about what matters. Even ignoring them involves recognising that they can be ignored.

Now imagine that drafting messages becomes almost effortless. Someone can produce a longer update, contact more people or generate a personalised approach to every prospective customer.

That can improve communication when it helps the sender explain something clearly. It can also increase the volume of material that other people must assess.

The sender’s saved effort may reappear in the recipient’s day.

This is a possibility rather than an inevitable outcome. The same tools could summarise updates, improve routing or remove unnecessary messages. The important issue is which cost the system is designed to reduce.

Attention has an owner

We often discuss attention as a resource businesses compete to capture. That language makes it easy to forget that attention belongs to someone.

An interruption spends part of another person’s life. Sometimes that expenditure is justified. A warning, a thoughtful invitation or a necessary question can be worth far more than the time it takes.

But treating every opportunity to reach someone as an entitlement produces a peculiar economy. The reward goes to whoever can impose the smallest individual demands on the largest number of people.

The demands remain small enough to dismiss. Their total cost is borne elsewhere.

This also changes what people need from communication. An accurate summary can help, but a summary of an irrelevant message is still an irrelevant message. Reducing length does not necessarily reduce the need to make a decision.

Better permission

A useful response begins before the message is written.

Does this person need to receive it? Do they need to act? Is the timing important? Could the information wait until they choose to look for it?

A team can make these questions easier by agreeing where different kinds of communication belong. Routine updates can be available without demanding an immediate response. Urgent requests can carry enough context to justify the interruption. Meetings can have a purpose that requires people to be present together.

These arrangements are modest. Their value comes from making attention predictable.

The same principle applies beyond work. A publication that arrives when expected and consistently respects the reader’s time earns a different relationship from one that repeatedly manufactures urgency.

Time returned

Success in communication is often measured by what the recipient does: opens, clicks, replies or attends.

There is another useful measure. How much effort did the communication save them?

A clear instruction can prevent a second conversation. A complete request can remove an afternoon of clarification. A decision recorded in the right place can spare ten people from asking the same question.

That kind of communication may produce fewer visible interactions precisely because it works.

If messages become abundant, restraint becomes a form of service. The ability to reach people will remain useful. So will knowing when to leave them alone.
