The Multitasking Myth: Why Doing Less Helps You Lead More

You've just stepped into your first leadership role. Your inbox is overflowing, your calendar is stacked, and three people need answers before lunch. So, you do what feels natural — you try to do everything at once. You answer emails during meetings, draft reports while fielding questions, and convince yourself that juggling it all is what good leaders do.

It isn't. And the sooner you understand why, the sooner you'll become the kind of leader your team actually needs.

The Illusion of Productivity

Do you pride yourself on being a master multitasker? Many of us believe that juggling multiple tasks at once makes us more productive. We wear it like a badge of honor, especially early in our careers when we feel pressure to prove ourselves. In reality, multitasking is a myth — one of the most persistent and harmful productivity myths in the modern workplace.

The human brain is not wired to focus on two cognitive tasks simultaneously. What we call multitasking is actually task switching — moving rapidly from one task to another, often with reduced efficiency and accuracy. Multitasking can look like trying to perform two tasks simultaneously, switching from one task to another, or performing two or more tasks in rapid succession. Regardless of the form it takes, the result is the same: divided attention, diminished output, and mounting frustration.

What Happens Inside Your Brain

When you switch between tasks, your brain must halt processing of the current rule set and load a new one for the next task. That halting, unloading, and restarting process takes a measurable toll on your cognitive resources and slows you down considerably. Research suggests that attempting to complete two or more tasks at once can take fifty percent more time or longer, depending on the complexity of the tasks involved.

Think about the last time you talked on the phone while checking email or tried to listen in a meeting while drafting a message on your laptop. You probably missed something important in both activities. The extent of this problem might come as a shock, but the science is clear: we are working harder while accomplishing less.

Multitasking triggers conflict in the brain, increasing stress hormones and reducing the quality of our thinking. For emerging leaders, this is especially dangerous. Your early decisions set the tone for your team's culture. If you are constantly scattered, your team will mirror that energy. If you are focused and intentional, they will follow that example instead.

The Real Cost for New Leaders

As a first-time supervisor, you are not just managing tasks — you are managing people, expectations, and your own credibility. Every time you half-listen to a team member because you are scanning your inbox, you send a message that they are not your priority. Every time you rush through a decision because you are juggling three other things, you increase the likelihood of errors that erode trust.

The truth is that we are not multitasking when we think we are. We are toggling back and forth between activities, giving each one a fraction of our attention. In many cases, we would be far more efficient if we single-tasked instead, creating a conscious start and stop for each activity. 

Task switching — the ability to shift focus among tasks, focusing on one at a time — sounds less impressive than multitasking, but it is honest about what the brain can actually do. And honesty with yourself is where strong leadership begins.

Reclaiming Your Focus

The good news is that you can retrain your brain to prioritize single-tasking, embrace deep work, and achieve more in less time. This is not about doing less. It is about doing what matters with your full attention.

Start with time-blocking. Dedicate specific windows in your day to specific types of work. Reserve your morning energy for strategic thinking and complex decisions. Batch similar tasks together — respond to all emails in one focused session rather than scattering replies throughout the day. When you are in a conversation with a team member, close your laptop and be fully present. These small shifts communicate respect and build the trust that new leaders desperately need.

Consider building transition rituals between tasks. Take thirty seconds to close one mental file before opening another. Write down where you left off so your brain can release it. These micro-habits reduce the cognitive cost of switching and help you arrive at each new task with clarity rather than residual mental clutter.

Leading by Example

Here is what many new supervisors miss: your team is watching how you work, not just what you assign. If you model frantic multitasking, you implicitly give your team permission to operate the same way. If you model focused, intentional work, you create a culture where depth is valued over the appearance of busyness.

This is a leadership choice, not just a productivity hack. When you protect your own focus, you give yourself the mental space to think strategically, respond thoughtfully, and show up as the leader your team deserves.

Moving Forward

If you are ready to reclaim your focus and boost your productivity, start small. Choose one meeting tomorrow where you will not check your phone. Pick one hour where you will close every tab except the one that matters. Notice how it feels to give something your complete attention. That feeling — of presence, of competence, of calm — is what effective leadership is built on.

Tools like time-blocking, task batching, and executive function coaching provide clear pathways to break free from the multitasking trap. You do not have to figure this out alone. Consider working with a coach or mentor who can help you develop the focus habits that will serve you throughout your leadership journey.

The multitasking myth told you that doing everything at once made you valuable. The truth is simpler and more powerful: the leader who is fully present for one thing at a time will always outperform the one who is half-present for everything.
