#2 of 10 Digital Commandments

“2. Thou shalt not multitask
A study at The British Institute of Psychiatry showed that checking your email while performing another creative task decreases your IQ in the moment by 10 points. This decrease is the equivalent of the effects from not sleeping for 36 hours—and exhibits more than twice the impact of smoking marijuana. In a study of 1,000 of its employees, Basex, an information-technology research firm, found striking data showcasing inefficiency. It was determined that 2.1 hours per day is lost to interruptions. This figure indicates over 26 percent of the average workday is wasted due to multitasking and unwanted interruptions. Jordan Grafman, chief of the cognitive neuroscience section at the National Institute of Neurological Disorders and Stroke, explains, “There’s substantial literature on how the brain handles multitasking. And basically, it doesn’t …what’s really going on is a rapid toggling among tasks rather than simultaneous processing”  (250-257).

Multitasking is junk food for the brain (2582). [My favorite quote in the book!]”
