Why Do We Doodle While Talking on the Phone Even When We Know Better?

The Cognitive Science of Doodling: Why Your Brain Craves the Pen

When you pick up a pen and start tracing loops or geometric patterns during a long-winded phone call, you aren't just killing time—you are actively managing your brain’s cognitive resources. The human brain is a high-energy engine that hates stagnation. When we engage in passive listening, such as sitting through a monotonous conference call or a lengthy update from a friend, our brain’s Default Mode Network (DMN) begins to assert itself. This network is responsible for daydreaming, mind-wandering, and internal reflection. Left unchecked, the DMN will pull your focus away from the conversation and toward your own personal worries or future plans, effectively putting your processing power on 'autopilot.'

This is where doodling acts as a cognitive anchor. By engaging in a low-effort, repetitive motor task, you provide your brain with just enough stimulation to keep the DMN from hijacking your focus. In a seminal study published by Professor Jackie Andrade at the University of Plymouth, participants were asked to listen to a dull, two-and-a-half-minute voicemail while either doodling or sitting quietly. The results were striking: the doodling group recalled 29% more information than the non-doodlers. The act of drawing provides a 'cognitive buffer.' It occupies the idle capacity of the brain without requiring the high-level executive function needed for complex tasks like writing an essay or solving a math problem. Consequently, the listener remains in a 'Goldilocks' zone of arousal—not so bored that they drift off, but not so challenged that they lose track of the speaker’s words.

Furthermore, the tactile nature of doodling creates a multisensory bridge. When you draw, you are incorporating motor feedback into your auditory processing. This dual-channel engagement strengthens the neural encoding of the conversation. Think of it as adding a 'tag' to the information you are receiving; by tethering the auditory data to the physical act of moving your hand, you create a more robust memory trace. It is an unconscious form of self-regulation that allows your brain to stay alert in environments that would otherwise induce fatigue or mental 'zoning out.' Rather than a sign of distraction, your scribbles are evidence of a brain working hard to maintain its connection to reality.

Turning Doodling into a Productivity Tool

If you find yourself doodling during meetings, don't feel the need to stop. Instead, lean into it as a legitimate productivity hack. To maximize the benefits, keep your doodling 'mindless.' The goal is to reach a state of flow where you aren't thinking about what you are drawing—if you find yourself carefully sketching a realistic portrait, you are likely using too much cognitive bandwidth, which will detract from your listening. Stick to repetitive patterns like swirls, geometric shapes, or abstract shading.

In a professional setting, if you are worried about appearances, keep your doodles small and contained within the margins of your notes. This frames the activity as a component of your note-taking process rather than a distraction. If you are a manager or educator, consider providing paper and pens during long, information-heavy sessions. By normalizing the practice, you create an environment where participants are more likely to stay engaged. When you view doodling as a tool for focus rather than a habit of the disengaged, you can use it intentionally to power through your most tedious calls and meetings with total clarity.

Why It Matters

The science of doodling challenges our fundamental assumptions about how we learn and pay attention. In an age of constant digital distraction, we are often told that 'multitasking' is the enemy of focus. However, the study of doodling reveals that not all secondary tasks are created equal. By understanding that our brains thrive on a certain level of sensory input, we can design better work environments and educational systems that account for the human need for movement. This research is particularly vital for those with ADHD or other attention-related challenges, for whom fidgeting and doodling are not just preferences but necessary mechanisms for regulating arousal levels. Recognizing the value of these 'mindless' movements allows us to be kinder to ourselves and more effective in our cognitive output, turning a common office habit into a scientifically backed strategy for sharper, more attentive communication.

Common Misconceptions

A major myth is that doodling is a symptom of boredom or a lack of interest in the speaker. While you might doodle when bored, the action itself is an attempt to reverse that boredom and stay engaged. It is a proactive, not reactive, behavior. Another common misconception is that doodling is a 'distraction' that splits your focus. Many people believe that if you aren't looking directly at the speaker or sitting perfectly still, you aren't listening. This ignores the fact that human attention is not a zero-sum game; our brains can often process more efficiently when we allow a secondary, low-demand task to run in the background. Finally, people often assume that 'doodling' implies an artistic endeavor. There is a fear that drawing makes you 'look' like you are working on a project rather than listening. In reality, the most effective doodling is often the least artistic. The cognitive benefit comes from the repetition, not the final aesthetic result, which is why simple shapes are far more effective for focus than complex sketches.

Fun Facts

• Doodling activates the brain's Default Mode Network, which is the same network involved in daydreaming and creative problem-solving.
• The word 'doodle' likely derives from the German 'Dudeltopf' or 'Dudeldop,' meaning a simpleton or fool, but today it represents a sophisticated cognitive tool.
• Famous historical figures known for their prolific doodling include Leonardo da Vinci, Sylvia Plath, and several U.S. Presidents, including John F. Kennedy.
• Studies suggest that doodling can also help reduce stress by lowering cortisol levels through repetitive, soothing motor activity.
