Humans cannot multitask

Multicosts of Multitasking.
Cerebrum
This article explores the cognitive and neurological implications of multitasking, emphasizing that true multitasking—handling multiple tasks simultaneously—is largely a misnomer, as the brain switches between tasks rather than performing them concurrently. Key brain networks, such as the frontoparietal control, dorsal attention, and ventral attention networks, are involved in managing task-switching demands, but their capacity is limited. Task-switching results in performance costs, including slower response times and reduced accuracy. Media multitasking, prevalent in today's attention economy, exacerbates cognitive challenges, with heavy media multitaskers often underperforming on tasks requiring sustained attention, working memory, and impulse control. Despite potential benefits in creative problem-solving, multitasking generally imposes cognitive trade-offs. Future research aims to address causality, brain mechanisms, and potential contexts where multitasking might yield advantages, offering insights into optimizing cognitive performance in a media-saturated world.

Here’s practical advice from a neuroscientist: Don’t try to multitask. It ruins productivity, causes mistakes, and impedes creative thought. Many of you are probably thinking, “But I’m good at it!” Sadly, that’s an illusion. As humans, we have a very limited capacity for simultaneous thought -- we can only hold a little bit of information in the mind at any single moment. You don’t actually multitask, you task-switch. This wastes time, makes you error-prone and decreases your ability to be creative. I am going to tell you why and what you can do about that.

Don't believe the multitasking hype, scientists say. New research shows that we humans aren't as good as we think we are at doing several things at once. But it also highlights a human skill that gave us an evolutionary edge.
