People multitask because they believe they can get more done, but Nass has solid evidence that the opposite is usually the case.
Common belief among many individuals in the age of information, including many millennials, show the belief in the power of multitasking in daily life. As stated by Rhiengold, this is common practice for many young individuals. But contrary to popular belief, mental health takes a great toll as multitasking is utilized more. A study by Time Magazine recently describes how neuroscientist, Dr. Kubu, took time to research the mental activity required in multitasking. His results showed that when trying to utilize it to complete tasks, many were not only unable to complete either task, but are having a false sense of doing two things at once, but doing singular tasks in rapid succession. This does not help in trying to complete work or in becoming efficient.
