In a compelling examination by "Stuff You Should Know," hosts Josh Clark and Chuck Bryant dissect the pervasive concept of multitasking. They challenge the conventional wisdom that multitasking is efficient, exposing it as a common productivity pitfall and debunking it instead as rapid task-switching, which can hamper performance and elevate stress. Drawing upon the scientific underpinnings of cognitive function, the duo delves into the brain's executive controls and how the productivity myth of multitasking can result in a measurable "switching cost"—the lag time and decreased accuracy that follow when juggling multiple tasks.
The episode extends beyond mere critique, offering practical advice on how to keep our task management in check. With the increase in digital distractions, the discussion provides actionable strategies such as limiting notifications and reducing social media usage to bolster concentration. Notably, the conversation touches on the phenomenon of media multitasking in the age of multi-screen interactions, while recognizing the exceptional few who can handle such cognitive demands effectively. With a slight speculative nod to gender differences in multitasking abilities, Clark and Bryant conclude by arguing in favor of focused, singular task engagement as a means to maximize productivity and sharpen focus, suggesting techniques like the Pomodoro Technique as valuable tools for the modern professional.

Clark and Bryant debunk the idea of multitasking, clarifying that what we regard as multitasking is actually rapid task-switching, which is inefficient and undermines performance. They highlight the brain's adaptive executive control, which prioritizes tasks, underlining that while managing simple tasks might be possible, complex tasks pose a challenge. The notion of a "switching cost" is introduced, detailing the resulting lag in productivity due to time taken to transition between tasks. Clark emphasizes that multitasking deteriorates task performance and can lead to a significant loss in productivity, increased stress, a higher likelihood of errors, and is particularly detrimental for individuals with ADHD.
The brain's information processing capabilities are limited, especially when multitasking. The prefrontal cortex, essential in focusing on tasks, has to divide its attention to manage multiple activities, which is challenging. Overloading the prefrontal cortex with complex tasks can quickly become overwhelming and impair productivity.
Clark and Bryant address how multitasking is often confused with the distractions that accompany it, especially in educational contexts, where the negative impacts on grades are noticeable. To minimize these distractions, they recommend limiting notifications on digital devices. Bryant himself practices turning off notifications to maintain focus, and both hosts advocate for minimizing social media to manage tasks more efficiently.
The surge in media multitasking with multiple screens is a significant trend. However, the ability to manage multiple tasks effectively is rare, with about 2.5 percent of the population known as "supertaskers" who can maintain performance. Josh Clark speculates that women may have a higher capacity for this than men. This ongoing rise in multi-screen interactions underscores the importance of understanding the impact of technology on cognitive abilities.
Clark stresses that multitasking is not the productivity booster it's assumed to be. It's a harmful practice that often leads to inefficiencies and diminished productivity and focus. The discussion suggests avoiding excessive multitasking and exploring alternative methods, such as the Pomodoro Technique, to boost productivity and focus more effectively by working on one task at a time before taking a break.
1-Page Summary
Clark and Bryant address the common misunderstanding related to multitasking, explaining that humans are not actually multitasking but quickly switching between tasks, which is less efficient and degrades performance.
Clark clarifies that what many people consider multitasking is, in fact, the brain flipping back and forth between tasks, not performing them simultaneously. This requires the brain to decide which activity is a priority, engaging in what is known as adaptive executive control. Bryant and Clark emphasize that while the brain might manage simple tasks at once, it struggles to multitask with more complex or numerous activities.
They discuss the concept of a "switching cost"—a lag or loss of productivity due to the time spent transitioning from one task to another. Clark explains that the brain requires a moment to switch between activities, and it's effectively inactive during that time. Every switch incurs inefficiencies, with this cost being notably higher for people with ADHD, who have a deficit in reducing the switching cost compared to those without ADHD.
Attempting to multitask is not only futile but also detracts from performance, as noted by Clark. When people try to perform multiple tasks, ne ...
Multitasking is a myth
The brain's capacity for handling information is finite, and multitasking poses significant challenges, particularly to the prefrontal cortex, which plays a crucial role in coordinating our activities.
The prefrontal cortex, which is active when we pay attention, spans the left and right sides of the brain and coordinates activity when we focus on a single task. However, when we attempt to multitask, this area of the brain has to divide its resources.
The ineffectivene ...
The brain has limits on information processing abilities
The hosts discuss the various ways in which multitasking and distractions impact performance and focus, particularly in the academic context. They note the negative effects of high levels of multitasking on grades and emphasize the need to distinguish between multitasking and the distractions that often accompany it.
Chuck Bryant and Josh Clark acknowledge that modern communications like email, texting, and push notifications are frequent sources of distractions, which can contribute to multitasking and harm concentration. To combat these interruptions, the hosts suggest that notifications on devices should be limited.
Chuck Bryant personally recommends turning off notifications to reduce d ...
Distractions and interruptions are related to multitasking
The landscape of media consumption is continually evolving, and recent trends indicate a significant rise in media multitasking, where individuals engage with multiple forms of technology simultaneously. Studies have illuminated this shift, revealing how the simultaneous use of media devices has increased over the years.
While multitasking across various screens has become a common aspect of daily life, it’s crucial to recognize that only a tiny fraction of the population may truly excel at this practice. Bryant mentioned the concept of "supertaskers," a term referring to those rare individuals who can effectively manage multiple tasks without a decline in performance.
Research from the University of Utah highlights the existence of "supertaskers," who represent a small subset of the population. In an observational study including 400 people, they found that only about 2.5 percent could be considered supertaskers, hinting that for the vast majority, multitasking could lead to a drop in productivity or effectiveness.
The discussion also touched on the possibility that the ability to juggle multiple tasks effectively might be ...
Media multitasking using multiple screens is increasingly common
Clark addresses a common but often counterproductive strategy utilized by many in today’s fast-paced world: multitasking. He suggests that multitasking may not be as effective as people believe and implies that reducing multitasking could be beneficial for enhancing productivity and focus.
Clark notes that multitasking has become ingrained in modern life. Yet, he implies that these simultaneous activities might not yield efficiency in our professional and personal tasks. Instead, he points out that the frequent switching between tasks can actually lead to inefficiencies and a notable loss in productivity.
The transcript suggests that because of the drawbacks associated with task switching, strategies to avoid excessive multitasking should be considered. It implies that doing so could help individuals maximize their productivity and narrow their focus ...
Excessive multitasking should be avoided for productivity and focus
