The Myths and Risks of Multitasking

Updated: Jun 11

In a world that prizes efficiency and productivity, multitasking has often been heralded as a desirable skill. However, recent research suggests that the reality of multitasking is far from its glorified perception. Studies from prestigious institutions like Stanford University, the University of London, and the University of Sussex have shed light on the significant drawbacks of multitasking, particularly its impact on memory, focus, and even our IQ levels.

1. Memory and Focus: The Stanford Study

A study from Stanford University found startling evidence regarding the effects of multitasking on memory and attention. Contrary to the belief that multitasking enhances our ability to handle various tasks simultaneously, the study revealed that those who engage in multitasking struggle more with remembering information compared to those who focus on one task at a time. This finding is particularly concerning in our daily lives, where retaining information is crucial.

Moreover, the ability to focus, an essential aspect of productivity, was also found to deteriorate in multitaskers. Additionally, it can hinder one's ability to learn effectively. The need to focus is essential for learning, and the constant shift in attention that comes with multitasking can impede this process. This decline in concentration can lead to a decrease in the quality of work and engagement as the mind is constantly diverted by various tasks, preventing deep engagement with any single activity.

2. IQ Levels and Multitasking: Insights from the University of London

Another surprising revelation comes from the University of London, where researchers discovered that multitasking could lead to a temporary decline in IQ. The study showed that participants who multitasked experienced a drop in their IQ comparable to what one might experience after a night without sleep. This decline in cognitive capacity is a serious blow to the idea that multitasking makes us smarter or more capable.

3. Anxiety, Chronic Stress, and Feeling Impatience

The mental toll of multitasking extends beyond cognitive decline. It has been found to increase anxiety and negative emotions, making individuals feel more irritable and impatient and even leading to chronic stress. This is partly because the brain is naturally more comfortable focusing on one task at a time, and multitasking forces it to juggle multiple things simultaneously.

4. Emotional Intelligence and Decision Making:

The cognitive load of multitasking can affect emotional intelligence. It hinders the ability to read emotional cues and respond appropriately, leading to misinterpretations and inappropriate responses. Decision-making capabilities are also impaired due to divided attention and reduced ability to concentrate.

5. Cognitive Flexibility and Strategic Thinking: Constant task-switching associated with multitasking can lead to rigid thought processes, hampering ability to adapt and strategize effectively.

Behavioral Change Strategies

Embracing a more focused approach to tasks can enhance cognitive health and work quality. Based on the theory of behavioral change, here are some strategies to shift away from multitasking:

  1. Setting Specific Times for Email Checking: Reduces the habit of constant checking and the associated distractions.

  2. Allocating Social Media Time: Reserve social media usage for breaks to minimize work disruptions.

  3. Avoiding TV During Work/Studies: Helps maintain focus and enhances information retention.

  4. Mindful Eating During Meetings: Focus on the meeting content rather than eating, to enhance engagement and reduce distractions.

  5. Prioritizing Tasks: Focus on one task at a time to improve efficiency and task performance.


The evidence suggests that the downsides of multitasking, such as impaired memory and reduced focus, outweigh its perceived benefits. Leaders and professionals can benefit from adopting a more singular focus in their tasks, potentially enhancing their emotional intelligence, decision-making, and strategic planning capabilities. By implementing behavior change strategies, individuals can gradually shift away from multitasking habits towards more focused and effective work practices.
