Multitasking is debunked as a myth by Josh Clark and Chuck Bryant, pointing out that attempts at multitasking lead to inefficient work and higher error rates. Instead of performing multiple tasks simultaneously, humans engage in rapid task switching, which incurs a "switching cost" in terms of time and productivity. No progress is made during the brain's transition period between tasks, leading to a significant loss in productivity. This inefficiency is particularly magnified in individuals with ADHD, who face even longer switching costs. Task switching can cause up to a 40% loss in productivity, especially in workplace situations where employees divide their attention between tasks like checking social media or email, ultimately resulting in decreased work quality and an increase in mistakes.
Josh Clark introduces the concept of a 'processing bottleneck' conveying the brain's restricted capacity to handle tasks concurrently. The brain can manage, to some extent, two tasks at once before performance drops. Any further, and performance suffers greatly due to what is known as the "response selection bottleneck," this occurs when the brain must prioritize tasks, emphasizing the inefficiency of multitasking. Although there is some evidence to suggest that women may be slightly better at multitasking than men, Clark and Bryant stress the research is inconsistent and inconclusive. Contrasting brain connection patterns in men and women may point to different cognitive strengths, but not necessarily to enhanced multitasking abilities.
Discussing the dangers of distracted driving, Josh Clark and Chuck Bryant underscore how activities like eating or drinking while driving increase the risk of accidents. For example, eating while driving, particularly complicated foods, increases the risk of an accident by 80%, according to the National Highway Traffic Safety Administration (NHTSA). Smartphones have contributed to an increase in distracted driving crashes; however, despite being a serious issue, there is insufficient data to suggest that smartphone use is more dangerous than other distractions, such as eating or drinking while driving.
The need to minimize notifications and distractions to maintain focus is highlighted by Clark and Bryant. They promote techniques, like the Pomodoro method, which encourage sustained concentration by limiting interruptions. By turning off notifications and managing outside communications, individuals can better concentrate on tasks at hand. The Pomodoro Technique, which consists of 25 minutes of focused work followed by a short break, is presented as an effective strategy to enhance attention and productivity in a world rife with potential diversions.
1-Page Summary
Josh Clark and Chuck Bryant dissect the notion of multitasking, revealing that it is, in fact, a myth and that human attempts to multitask lead to less efficient work with more errors.
The hosts delve into the mechanics of what multitasking really entails and why it's a flawed practice.
Josh Clark explains that what is often considered multitasking is actually just rapid task switching, similar to how single CPU computers operate by quickly jumping back and forth between tasks. This requires a pause as the brain stops one task and starts another, with no progress being made on either task during this refractory period.
Chuck Bryant mentions the "switching cost" when you leave a task to do something else, like sending an email, and then return to the original task. Although it may seem seamless, there's a cost in the time it takes for your brain to refocus on the original task. Clark and Bryant emphasize that, when switching from one task to another, especially when attempting two tasks at once, there is a loss of productivity known as switching cost.
The psychological refractory period effect describes how the response to a second task is delayed because the brain is still processing the first task. Chuck Bryant explains that while it seems like you’re multitasking, you're actually doubling the time it takes to complete tasks due to this switching cost. The hosts agree that during the time the brain is switching tasks, there's no progress made on either task.

Multitasking is impossible for humans and makes tasks take longer and have more errors
Clark introduces the concept of a 'processing bottleneck', indicating that the brain has a finite capacity to handle multiple tasks at once. This capacity is pushed to its limit when we attempt to multitask.
The conversation revolves around the brain's limitations when it comes to multitasking. Clark and Bryant explore how multitasking can overload the brain's core functions such as attention and working memory, which is particularly apparent in individuals with ADHD. Bryant suggests that while managing one task is ideal, two tasks can be handled to some extent, but trying to accomplish three tasks concurrently is ill-advised.
A study from Vanderbilt University points to a phenomenon known as the "response selection bottleneck," where the brain must choose which task is more critical when faced with several actions. During task-switching moments, Clark explains, the brain doesn't make progress on any task, illustrating the inefficiency of multitasking.
It's also mentioned that the brain may favor tasks based on the pleasure they provide or their potential to accomplish a sub-goal. Clark emphasizes that such multitasking, especially involving various media screens, is associated with lower density of gray matter in certain brain regions, but the implications of this are not fully understood.
Bryant dives into research regarding gender differences in multitasking abilities, noting the inconsistent and sometimes questionable quality of many studies. Clark acknowledges that definitive conclusions are elusive, and the research isn't clear on whether women may possess slightly ...
Trying to multitask overloads the brain's limited processing ability
Josh Clark and Chuck Bryant discuss the hazards of distracted driving, expressing particular concern about common but dangerous behaviors like eating or drinking while in control of a vehicle.
Bryant cites alarming statistics from the National Highway Traffic Safety Administration (NHTSA), noting that 65% of near-miss accidents are caused by drivers who are eating or drinking. He also mentions that doing so increases the risk of being involved in an accident by 80%. Coffee is singled out as an especially perilous beverage to consume while driving.
Eating while driving presents a particular danger because it often involves foods that can divert the driver's attention, such as jelly-filled donuts, which can drip, or fried chicken, due to the necessity of licking fingers or its typically two-handed consumption. Consuming fried chicken with bones requires even more attention and hands, which further compounds the risk.
Despite these dangers, Clark points out the lack of comprehensive data regarding crashes caused specifically by smart ...
Driving while performing another task is very dangerous
Podcast hosts Chuck Bryant and Josh Clark discuss how limiting notifications and distractions is crucial for maintaining focus and productivity, proposing techniques to aid in this process.
The hosts touch upon the loss of productivity due to distractions, which can severely impact activities that require concentration, such as schoolwork. This discussion points to a broader understanding that effectively managing interruptions and outside communication is vital to sustaining attention on a given task.
Chuck Bryant specifically recommends turning off notifications on one’s phone, arguing against the need to be notified of every social media interaction, such as comments on posts. Meanwhile, Josh Clark agrees and suggests that turning off ringtones and other notifications can be fundamental steps toward enhancing one’s ability ...
