Consider these two hypothetical afternoons:
A program director spends three uninterrupted hours developing a strategy, with a clear objective and authority to make decisions.
Another program director spends three hours moving among staff questions, a funder request, a sensitive personnel issue, a shifting deadline, and an unresolved decision requiring someone else’s approval.
The calendar shows three hours in each case. But it tells us little about the fragmentation, uncertainty, or competing demands on attention. The second director may finish the afternoon exhausted, with little sense of progress on the work that matters most. When that becomes the daily pattern, it can contribute to burnout.
Managers and leaders need time to think through their work, support their teams, and determine direction. They need space to reflect before making consequential decisions. Yet many spend their days responding to whatever demands their attention next.
Understanding cognitive load helps explain why this is so draining—and what we can do about it.
The workload our calendars don’t show
In plain language, cognitive load refers to the demands placed on our limited capacity to hold and process information while doing something. It helps explain why having an available hour does not always mean having the capacity to use it well.
Think about what you might be carrying into that hour: an unresolved disagreement, a decision you cannot make without approval, several competing deadlines, and the awareness that someone on your team is struggling.
Even when you turn to another task, those concerns may follow you. Researcher Sophie Leroy calls this “attention residue”: some of our attention remains with previous work as we try to engage with what comes next.
Our working days can become mentally demanding in several overlapping ways:
Fragmentation: We repeatedly switch among tasks, conversations, and problems.
Uncertainty: We navigate changing circumstances or unclear expectations.
Competing priorities: We continually decide what deserves attention and what can wait.
Relationship demands: We manage sensitive interactions with colleagues, supervisors, and people we lead.
Information overload: We absorb, evaluate, and respond to more information than we can comfortably process.
These demands do not all appear on a task list. But they shape how much attention and judgment we can bring to the work.
When the mission adds to the load
For mission-driven professionals, the work can introduce additional pressures.
An expansive mission requires repeated decisions about which important needs will go unmet. Accountability extends in multiple directions—to funders, communities, boards, partners, and staff. Progress on issues such as climate change, education, poverty, and justice can be slow, uncertain, and difficult to measure.
The stakes can also make it harder to set work aside. There is always another need, another opportunity, or another problem that deserves attention. Yet the professionals I speak with yearn for something closer to that first afternoon: uninterrupted time to develop a strategy, think through a challenge, and identify a path toward meaningful change. That opportunity to contribute is often what brought them to the sector.
Creating those conditions requires us to ask: What makes this work mentally demanding, and which of those demands can we change?
Four leadership traps—and ways to address them
In my work with leaders, I’ve seen a few traps that managers fall into which increase cognitive load. The intentions behind these are good but they result in create complexity for themselves and the team.
1. Over-responsibility: carrying more than is reasonably yours to hold.
Leaders can begin to feel responsible for every unresolved problem, every staff member’s experience, and every outcome. They monitor work that belongs elsewhere, step in before others have a chance to act, or feel compelled to fill every organizational gap.
How to fix it: The first step is to distinguish what you are accountable for, what you can influence, and what belongs to someone else. Supporting a colleague does not always require assuming ownership of their problem. Some gaps require an explicit organizational decision about staffing, resources, or scope.
2. Overcommitment: adding work without deciding what will give.
Every new commitment introduces more than another task. It brings decisions, coordination, follow-up, and expectations. When leaders keep adding priorities, they leave staff to resolve the conflicts among them.
How to fix it: Limit active commitments and explicitly identify what will wait. When new work arrives, ask what will be postponed, reduced, reassigned, or stopped. Prioritization becomes useful when it changes what people are expected to do.
3. Failure to delegate: keeping too much thinking and decision-making at the top.
Delegation can fall short when leaders assign tasks but retain every meaningful decision. Staff must repeatedly seek approval, while the leader remains involved in the details of everything.
How to fix it: Effective delegation includes a clear outcome, appropriate authority, access to resources, and agreed points for checking in. It also requires allowing people room to use their judgment. Done well, delegation reduces bottlenecks and helps others develop.
4. Unclear commitments and decision-making: requiring people to keep figuring out how work moves forward.
Who owns this? Who needs to contribute? Has a decision been made? Can we proceed?
When those questions remain unresolved, people expend attention navigating the process.
Decisions may be revisited because their rationale was never recorded or because nobody knows what would justify reopening them.
How to fix it: Clarify roles and decision authority. Record consequential decisions, who will act on them, and the circumstances that would warrant reconsideration. Make it easy for people to find the current answer.
Protecting the capacity to think
These changes need to be accompanied by protected time for focused work. Strategic thinking cannot depend entirely on finding an unexpected gap between meetings.
At an individual level, it can help to record commitments and leave a brief note before switching tasks: where you stopped, what comes next, and when you will return.
At an organizational level, leaders can establish response expectations and protect blocks of time when people can concentrate. The goal is to preserve capacity for the judgment, creativity, and relationships the mission requires.
As you look at your week, consider what you are asking yourself—and your team—to keep holding in mind. What could be clarified? What could be delegated? Which commitment could wait? Which decision could finally be settled?
Those choices can create more room for the thoughtful work people came here to do.
